Congestion on the roads has a variety of sources. These include accidents of course, reductions in road capacity, irrational human driving behaviours and others, but most of all you get congestion when more cars are trying to use a road than it has capacity for.
That’s why the two main success stories in congestion today are metering lights and downtown congestion charging. Metering lights limit how fast cars can enter the highway, so that you don’t overload it and traffic flows smoothly. By waiting a bit at the metering light you get a fast ride once on the highway. Sometimes though, especially when the other factors like accidents come into play, things still gum up.
Now that more and more cars are connected (by virtue just of the smartphone the driver carries if nothing else) the potential will open up for something else in congestion — finding ways to encourage drivers to leave a congested road. read more »
I’m just back from the “ITS World Congress” an annual meeting of people working on “Intelligent Transportation Systems” which means all sorts of applications of computers and networking to transportation, particularly cars. A whole bunch of stuff gets covered there, including traffic monitoring and management, toll collection, transit operations etc. but what’s of interest to robocar enthusiasts is what goes into cars and streets. People started networking cars with systems like OnStar, now known in the generic sense as “telematics” but things have grown since then.
The big effort involves putting digital radios into cars. The radio system, known by names like 802.11p, WAVE and DSRC involves an 802.11 derived protocol in a new dedicated band at 5.9ghz. The goal is a protocol suitable for safety applications, with super-fast connections and reliable data. Once the radios in the car, the car will be able to use it to talk to other cars (known as V2V) or to infrastructure facilities such as traffic lights (known as V2I.) The initial planned figured that the V2I services would give you internet in your car, but the reality is that 4G cellular networks have taken over that part of the value chain.
Coming up with value for V2V is a tricky proposition. Since you can only talk to cars very close to you, it’s not a reliable way to talk with any particular car. Relaying through the wide area network is best for that unless you need lots of bandwidth or really low latency. There’s not much that needs lots of bandwidth, but safety applications do demand both low latency and a robust system that doesn’t depend on infrastructure.
The current approach to safety applications is to have equipped cars transmit status information. Formerly called a “here I am” this is a broadcast of location, direction, speed and signals like brake lights, turn signals etc. If somebody else’s car is transmitting that, your car can detect their presence, even if you can’t see them. This lets your car detect and warn about things like:
The car 2 or 3 in front of you, hidden by the truck in front of you, that has hit the brakes or stalled
People in your blind spot, or who are coming up on you really fast when your’re about to change lanes
Hidden cars coming up when you want to turn left, or want to pass on a rural highway
Cars about to run red lights or blow stop signs at an intersection you’re about to go through
Privacy is a big issue. The boxes change their ID every minute so you can’t track a car over a long distance unless you can follow it over every segment, but is that enough? They say a law is needed so the police don’t use the speed broadcast to ticket you, but will it stay that way?
It turns out that intersection collisions are a large fraction of crashes, so there’s a big win there, if you can do it. The problem is one of critical mass. Installed in just a few cars, such a system is extremely unlikely to provide aid. For things like blindspot detection, existing systems that use cameras or radars are far better because they see all cars, not just those with radios. Even with 10% penetration, there’s only a 1% chance any given collision could be prevented with the system, though it’s a 10% chance for the people who seek out the system. (Sadly, those who seek out fancy safety systems are probably less likely to be the ones blowing through red lights, and indeed another feature of the system — getting data from traffic lights — already can do a lot to stop an equipped car from going through a red light by mistake.) read more »
Since getting involved with Google’s self-driving-car team, I’ve had to keep silent about its internals, but for those who are interested in the project, a recent presentation at the intelligent robotics conference in San Francisco is now up on youtube. The talk is by Sebastian Thrun (overall project leader) and Chris Urmson, lead developer. Sebastian led the Stanley and Junior teams in the Darpa Grand Challenge and Chris led CMU teams, including BOSS which won the urban challenge.
The talk begins in part one with the story of the grand challenges. If you read this blog you probably know most of that story.
Part two (above) shows video that’s been seen before in Sebastian’s TED talk and my own talks, and maps of some of the routes the car has driven. Then you get Chris showing some hard technical details about mapping and sensors.
Part three shows the never before revealed story of a different project called “Caddy”: self-driving, self-delivering golf carts for use in campus transportation. The golf carts are an example of what I’ve dubbed a WhistleCar — a car that delivers itself and then you drive it in any complex situations.
If you want to see what’s inside the project, these videos are a must-watch, particularly part 2 (embedded above) and the start of part 3.
There’s lots of other robocar news after the Intelligent Transportation Systems conference, which I attended this week in Orlando FL. The ITS community is paying only minimal attention to robocars, which is an error on their part, but a lot of the technology there will eventually affect how robocars develop — though a surprising amount of it will become obsolete because it focuses on the problems caused by lots of human driving.
The list of robocar teams grows again with a new project from Oxford university, led by Paul Newman. Nissan is also involved, though the base vehicle is a Bowler Wildcat off-road vehicle.
The project sports a LIDAR design I have not yet seen, with 4 laser units on a mount spinning at what looks like 1-2hz, but they claim a 40hz sampling rate and do have very nice mapping results. They claim their localizer is very good, and demos show it working on rough off-road terrain. Some videos also see it doing waypoint driving without the LIDAR but they talk about why GPS is not adequate.
The claims about the vehicle have a British understatement. They say it will be 10-15 years before it’s ready for the roads, and talk mostly about simple problems like handling traffic jams — something Audi, BWM and VW have all claimed they will release in the middle of this decade, using simpler sensor systems. He also envisions a future arms-race where a car that can do 10 minutes/day of self-driving competes with one that can do 15.
Congestion is their main message it seems, citing the Dept. for Transport’s figures of a 25 billion pound cost for congestion in 2025 in the UK.
Boston Dynamics has gone even further with their latest model, AlphaDog
The AlphaDog’s legs are hydraulic, and so adding legs like this to a car which has a motor and compressor is not so far fetched. In this design they could easily fold up into the sides of a single person wheeled vehicle. In the video, the robot is shown carrying 400lbs of weights, and a range of 20km is claimed. You might not quite want to ride it yet, but that’s coming.
Let’s look at some of the consequences for transportation and cities:
Houses need not be on streets to have full access by small vehicles and cargo delivery robots. They can be on the side of hills and up stairs. Neighbourhoods can be built with just small lightly paved or graded paths so that the robot’s legs don’t disturb the terrain.
The robots may well, in a controlled environment, be able to place their feet with good precision. As such the path for a walking robot might look like just a series of stone pads dotting the grass — the way some paths for people look. In reality they would be more sturdy, but that’s what they could look like.
In developing countries which do not have infrastructure, they may never have to put in that much infrastructure. Combined with flying robots, delivery of goods can become possible to any location, and at high speed.
The world’s tourist destinations may become swamped with people who can ride a walking robot to remote locations where before the daunting hike kept the crowds down. There will be efforts to ban walking chairs, but the elderly and disabled will be able to fight such bans as discriminatory.
Indeed, for the disabled and aged, the walking chair robot might well open up lots of the world that is now closed. The main issue would be power and noise. The motors that power BigDog are very noisy. AlphaDog in the video is using external power.
Robotic cargo delivery (deliverbots) need no longer be limited to places you can roll up to. That can include places inside buildings, even up stairs.
Some Robocar updates, since with Burning Man and Singularity U my posting volume has been down:
BMW Highly Automated Driving
BMW has announced a prototype car with a “Highly Automated Driving” feature on the 5 series. The vehicle, which has logged 3,000 miles of minimal driver involvement, uses a vision system from the lane departure camera, maps, the ACC radar and high-accuracy GPS. It is claimed to handle allowing and doing highway merges. The system is not meant to allow the driver to take their eyes off the road, though, and his highway-only. The system was also called “ConnectedDrive Connect (CDC)” which strikes me as a somewhat awkward name.
BMW also recently demonstrated some other self-driving technology on test tracks and has a very active lab. With Volkswagen’s Temporary Auto Pilot, Mercedes and Audi all promoting concept cars with autonomous modes, German companies seem to be the most engaged in the field. BMW has also shown a “traffic jam assistant” similar to the Audi system below.
Audi EV A2 has traffic jam autopilot
Another concept car (An earlier Audi was used in the Pikes Peak challenge) from Audi will feature an autopilot for stop and go traffic. Here they combine lane-keeping and automatic cruise control, except at lower speeds where the risk is low. The driver still has to pay some attention, and when traffic gets moving again they must take full control. Still, it’s aimed at one of the greatest annoyances of commuting.
Made in Germany continues on the roads
The AutoNOMOS team reports success with their vehicle on the streets of Berlin, though so far only 80km of operation. They have 6 laser sensors, and claim that they believe the vehicles will soon be ready to deploy on private roads, but will need a decade of legal work to be used on the public streets.
Autonomous tractor out working the fields
For some time the concept of “precision agriculture” has been the high-tech hotspot in farming. Here, tractors equipped with GPS and other location technologies take detailed maps of the fields and the crops and custom control spray of fertilizers, pesticides and other substances according to data about what’s right for each small square. However, farmers are still at the controls. Some day, tractors may drive themselves and engage in many farm activities. In the fields, there is not usually much to run into and you don’t go very fast. On the other hand, most family farmers today farm as a lifestyle and aren’t looking to automate it, but agribusiness operators are.
A report from China Daily details a successful 286km trip by a vehicle from the National University of Defense Technology.
According to the report the vehicle did fully autonomous highway driving, and did not use GPS, just LIDAR, radar and vision systems. Modern robocars do not rely exclusively on GPS, as it is both inaccurate and goes out in certain regions, but they do like to use it to help them localize, so not using it at all suggests a good localizer. They also report handling fog, thunderstorms and poor lane markers, all good acheivements.
There is what appears to be a machine translated article with some photos. The external photo seems to show an unmodified car, the internal one shows what appear to be two stereo cameras left and right, though the article talks mostly about LIDAR and radar, not vision systems. Dai Bin, spokesman for the team has published papers on both LIDAR based obstacle avoidance and vision systems similar to the one used by Stanley in the Darpa desert challenge for off-road use.
It will be interesting to hear more about the work of this team.
In other news, BMW has announced that its 2014 i3 battery-electric car will also offer a combination of lane-keeping and adaptive cruise control](http://www.greencarreports.com/news/1064191_2014-bmw-i3-moves-us-closer-to-autonomous-driving-in-cities) while under 25mph, effectively being a “stop and go traffic autopilot.” This is an interesting early offering, since it’s easier to put this together at low speeds in the controlled highway environment.
Also included will be a detection system for impeding collisions which can apply the brakes, and a fully automatic parallel parking system (most earlier systems still needed human control of the brake, causing amusing-if-it’s-not-you accidents for people who didn’t think they had to do anything.)
A wrapup of robocar news from the past couple of weeks:
Nevada governor Brian Sandoval rides in Google Car
After Nevada’s recent legislation directing their DOT to explore legal operations for robocars in the state, the governor “took the wheel” of a Google car. Very positive impressions from the governor and DMV head.
A new student robocar team has sprung up in India. They’re still early but their goal of driving in the crazy Indian traffic is a daunting one. Robocars have many advantages at low speed, where the 360 degree vision of LIDARS makes them see more than a human will. Harder is modeling the behaviour of other vehicles and playing games of chicken.
More mainstream press articles
Mainstream press articles of the robocar future and the intermediate technologies are growing in number. Here’s Smartmoney on near-term technologies and a Slate piece that, like almost all mainstream press pieces, asks whether people are really willing to give up the freedom of driving. Perhaps I’m too immersed, but in my immersed perspective I have simply stopped wondering about this. There will be a few who think like the dodge ad but huge numbers of people keep asking me when they can get one.
IEEE conference at Stanford paints alternating views with optimism vs. long roadmaps
Last Saturday a small IEEE conference at Stanford covered car automation technologies, including a morning on autonomous vehicles with mixed views. Steven Shladover, for example has a decades long history in important projects like cars guided by embedded road magnets, ITS, cooperative cruise control and platooning, but he is highly skeptical of autonomous cars which drive with regular cars, insisting instead that dedicated lanes are the answer. He believes this will start by building dedicated lanes for express buses (BRT) — which is something there is political will to do in many cities — and then automating the buses in those lanes. Once this is done, cars can enter the lanes if they communicate properly with the other vehicles in the lane and the lane itself.
This infrastructure approach is simpler from a technical standpoint, but the building of new infrastructure is such a hard problem and point of slow progress that my bet, as readers know, is on robocars on ordinary streets. Without the BRT component, I view proposals for new robot-only lanes to be dead in the water. Still, it’s worth paying attention when somebody with lots of experience disagrees so fundamentally with your views.
Volkswagen, while having recently promoted their Temporary Auto Pilot, displayed a roadmap that was much slower, suggesting that having a car that could pick you up at the airport or park itself on streets was something we might see in 2028.
Another lesson from the conference was the extreme difficulty of introducing radical innovation through big automakers. Cars are perhaps the most complex product sold, as well as the most expensive consumer product for most. As a result the industry has created huge amounts of “process” to how it plans and innovates, and that process is not ready to accept much in the way of disruptive technology. As I wrote earlier about the radio as the potential place for innovation in cars, car makers are now considering the central console where the radio and other controls are found the “golden stack” and they want to be the provider of it. Especially because the stuff they sell there sells for a huge margin; people often pay $2000 for an in-car GPS that’s worse than what they get free in their phone or for $250 in the aftermarket.
German team gets permission for their robocar tests on city streets
The AutoNOMOS team at Freie Universität Berlin reports they have been approved to test on city streets. This testing will be similar to the testing Google has reported doing in California, with a safety driver and copilot in the car to monitor and take control in any situation that presents a safety risk. According to the New York Times, Google didn’t seek a specific permission but state officials did agree, when asked by the times, with the interpretation that a vehicle with a licenced driver responsible for vehicle operations was legal.
Porsche trying to make a very smart cruise control
While not up to Volswagen’s temporary auto pilot, which combines ACC with lane-following, Porsche is developing a learning automatic cruise control that will come to understand road curves and speed and drive better as it learns.
Lots of exciting news, even in the slow summer season. Disclaimer note: The Google car project is a consulting client of mine.
I often see people say they would like to see solar panels on electric cars, inspired by the solar-electric cars in the challenge races, and by the idea that the solar panel will provide some recharging for the car while it is running and without need to plug it in.
It turns out this isn’t a tremendously good idea for a variety of reasons:
You’re probably not going to get more than a couple hundred watts of PV peak power on a car with typical cells. Even properly mounted on a roof in a sunny place like California, each peak watt delivers an average of about 5 watt-hours in a day, so 200 watts gives you 1kw-h. That’s good for around 4 to 6 miles on today’s electric cars. Not a huge range boost.
While thin film panels don’t weigh a lot the power they provide during actual driving would normally be only a minor boost. My math suggests they weigh more than the battery for the power they will provide while operating.
Panels on a car will instead be mounted flat, cutting about 30% of their output. Normally you want to tilt to the angle of the sun.
Cars are often in the shade, even parked indoors. Unless you work to pick your parking to have sun all day, you’ll only get a fraction of the power.
If you do leave your car in the sun, in many places that means it will get quite hot, you’ll burn up some of the solar energy cooling it down. (Indeed, the solar panels sometimes found on today’s hybrids and EVs don’t charge the battery, they just run a cooling fan.)
The worst one: If your battery is not somewhat discharged, it doesn’t have any place to put the solar energy, and so it is just thrown away. But due to range anxiety, people prefer their electric cars be kept full. It takes careful planning to use that energy.
A car is a very bumpy place, so you need more rugged panels than what you might put on a roof.
It is possible to get more than 200w on a car — some of the solar challenge cars that exist to be nothing but panels have gotten around a kw by using high price, high-efficiency panels. But it’s still generally much better to just put the panels on a roof where they will realize their full potential, and feed the grid, and charge from the grid.
However, on Friday I was teaching a class on the future of Robocars to my students at Singularity University and in the exercises some students wondered if they might do something for solar powered cars. (I was impressed since the students, having had only a short time to think about the issue, have to work to bring up something new.)
Robocars might solve some of the problems above, and thus possibly make sense as a place to put panels.
A robocar parks itself and can move. So one with a solar panel can move around to make sure it’s always in the sun, and that the sun is striking it from the right angle. It can’t move too far or too often without wasting some of the power, but it can do something.
When the batteries get so full that they are not making proper use of the solar energy, a robocar can find a charging station, not to charge but rather to sell excess power back to the grid and other cars. (This presumes charging stations are set up this way.)
Robocars could dock with other robocars that are more discharged and offer them the extra solar power, no charging stations involved — though fancy robotics are needed on the charging interface, or human beings who can do the connections.
If a robocar has an actuator that can tilt the panels, it can do even better. While an ordinary car could have this, an ordinary car would not have the ability to rotate in the plane of the ground to track the sun without another actuator.
It’s still not great, but it might improve things. Generally it still may be better to have the panels on rooftops and get the most from them. However, when we start thinking about super lightweight cars, cars that travel for under 100 watt-hours/mile, as well as higher efficiency panels, we might get some value if the panels are light.
It’s also expensive to install panels on top of existing facilities. Turns out that while panels are dropping below 1$/watt next year thanks to cheap Chinese capital and manufacturing, the cost of install is still over $2/watt. Cost of install on newly manufactured buildings — or cars — can be cheaper because it’s designed in from the start. The car already has the complex electrical system, while houses need to add them if they go solar.
People really are in love with the idea of a solar powered car. It’s not really possible to go green this way right now, but the future might bring something interesting.
The latest JD Power survey on car satisfaction has a very new complaint that has now the second most annoying item to new car owners namely problems with the voice recognition system in their hands-free interface. This is not too surprising, since voice recognition, especially in cars, is often dreadful. It also reveals that most new tech has lots of UI problems — not every product is the iPod, lauded from the start for its UI.
But one interesting realization in the study is that users have become frustrated at having too many devices with too many UIs. Their car (which now has a touchpad and lots of computer features) uses a different UI from their phone and computer and tablet and whatever. Even if the car has a superb UI, the problem is that it is different, something new to learn and remember.
One might fix this by having the same platform, be it iOS or Android on several of the devices, but that’s a tall order. Car vendors do not want to make a phone one one platform and tick off people used to the other platform.
The answer lies in something the car makers don’t like: Don’t put much of their own smarts in the car at all, and expect the user to slot their own mobile phone or tablet into the car. This might be done with something like Nokia’s “Terminal Mode” where the car’s screen and buttons can be taken over by the phone, or by not having a screen in the car at all, just a standard mounting place.
Some time ago I wrote that cars should stop coming with included radios as they used to 30 years ago, and let the slot in the dashboard where the radio and electronics go become a center for innovation. In particular innovation at the speed of consumer and mobile devices, not innovation at the speed of car companies. But there are too many pressures to stop this from happening. Car companies get to charge a lot for fancy radio and electronics systems in the cars, and they like this. And they like the control over the whole experience. But as they get more complaints they may realize that it’s not the right thing for them to be building. Especially not when the car (and the in-dash system) last for 10 to 15 years, while most consumer electronic devices are obsolete in 1-2 years.
There aren’t that many makes of cars, nor so many mobile platforms, so making custom apps for the car and the mobile platform isn’t that hard. In fact, I would expect you would see lots of competing aftermarket ones if they opened up the market to it. And open source ones too, built by fans of the particular cars.
An update on the backlog of robocar related news caused by my recent travel and projects:
Many people have noticed the new law recently passed in Nevada which directs the Dept. of Transportation to create guidelines for the introduction of self-driving cars on Nevada roads. Here is the text of the law. Because Google, whom I consult for on robocars, helped instigate this law, I will refrain from comment, other than to repeat what I’ve said before: I predict that most transportation innovation will take place in robocars because they will be built from the ground up and bought by early adopters. The government need merely get out of the way and do very basic facilitation. This is very different from things like PRT and new transit lines, which require the government’s active participation and funding.
You’ll find lots of commentary on the story in major news media. read more »
A new paper on trusted traveler programs from RAND Corp goes into some detailed math analysis of various approaches to a trusted traveler program. In such a program, you pre-screen some people, and those who pass go into a trusted line where they receive a lesser security check. The resources saved in the lesser check are applied to give all other passengers a better security check. This was the eventual goal of the failed CLEAR card — though while it operated it just got you to the front of the line, it didn’t reduce your security check.
The analysis shows that with a “spherical horse” there are situations where the TT program could reduce the number of terrorists making it through security with some weapon, though it concludes the benefit is often minor, and sometimes negative. I say spherical horse because they have to idealize the security checks in their model, just declaring that an approach has an X% chance of catching a weapon, and that this chance increases when you spend more money and decreases when you spend less, though it has diminishing returns since you can’t get better than 100% no matter what you spend.
The authors know this assumption is risky. Turns out there is a form of security check which does match this model, which is random intense checking. There the percentage of weapons caught is pretty closely tied with the frequency of the random check. The TTs would just get a lower probability of random check. However, very few people seem to be proposing this model. The real approaches you see involve things like the TTs not having to take their shoes off, or somehow bypassing or reducing one of the specific elements of the security process compared to the public. I believe these approaches negate the positive results in the Rand study.
This is important because while the paper puts a focus on whether TT programs can get better security for the same dollar, the reality is I think a big motive for the TT approach is not more security, but placation of the wealthy and the frequent flyer. We all hate security and the TSA, and the airlines want to give better service and even the TSA wants to be hated a bit less. When a grandmother or 10 year old girl gets a security pat down, it is politically bad, even though it is the right security procedure. Letting important passengers get a less intrusive search has value to the airlines and the powerful, and not doing intrusive searches that seem stupid to the public has political value to the TSA as well.
We already have such a program, and it’s not just the bypass of the nudatrons (X ray scanners) that has been won by members of congress and airline pilots. It’s called private air travel. People with their own planes can board without security at all for them or their guests. They could fly their planes into buildings if they wished, though most are not as big as the airliners from 9/11. Fortunately, the chance that the captains of industry who fly these planes would do this is tiny, so they fly without the TSA. The bypass for pilots seems to make a lot of sense at first blush — why search a pilot for a weapon she might use to take control of the plane? The reality is that giving a pass to the pilots means the bad guy’s problem changes from getting a weapon through the X-ray to creating fake pilot ID. It seems the latter might actually be easier than the former. read more »
Dodge has released a few interesting commercials for its Charger muscle car, somewhat prematurely pushing it as the antithesis of a robocar. Most amusing is the second ad which features an ugly car with a literal robot in the driver’s seat (something also seen in the Total Recall and I, Robot movies.) The first ad just has visuals of the car but actually mentions the Google car as one of the signs of increasing robot control. For some reason, the car, rather than the people behind it, is named the “leader of the human resistance.”
It’s easy to understand the sentiment behind these ads, particularly when you are trying to market a car as a powerful “man’s car” oriented to the thrill of driving. The people who want the car to drive itself are not like you, you want an exciting drive and this is the car for you, it says. (Other ads decry an online test drive, and cars that get lots of “boring” miles per gallon.)
The ad does pose an interesting question. When I talk, I often get people who say that they have no interest in a robocar (and that Americans won’t have interest in them) because they love to drive and would not give it up. I often ask back, “so do you love to commute?” It’s also clear from the example of New York City that Americans will certainly give up driving if it’s the right choice for their locale. People who grew up in L.A. don’t try to keep their car if they move to Manhattan, they do what makes sense for their new area.
Driving is fun, of course, particularly on an interesting road with a powerful car. Indeed, many find driving a stickshift even more fun in such circumstances, though they are almost gone from U.S. cars. (I’ve mostly owned stickshift cars though when I bought my most recent I ended up with an automatic where you can manually change the gears. But I find I don’t use the manual mode.) Being a passenger on windy roads is not nearly so much fun, and even makes many people a bit queasy, though this almost never happens to the driver even with the same moves.
Obviously I suspect the Dodge ad is wrong when it says that “robots will never take our cars.” But human driven cars will also exist for a long time, and not just in the muscle car market. Many people will enjoy — or even need — a car they can take control of when the road gets “interesting.” But in our ordinary driving, the road itself is rarely interesting. We may well take special trips where the software drives us to the fun road and we take over after that, though with a better safety system. On the other hand, when it comes to scenic drives, people will want to go slowly and be passengers, getting a chance to look out the windows and enjoy the view rather than concentrate on the road. We may see “tourist cars” in popular tourist spots which are either convertibles or have nearly transparent tops — reminding us perhaps of the bubble roof cars from the Jetsons — for those whose focus is on the view.
There will be a sector of the market that wholly buys into Dodge’s tongue-in-cheek message. I’m pretty confident in predicting that the opposite segment that embraces the technology will be more than large enough for it to find all the early adopters it needs. As people get used to the idea, it will then go mainstream, even if it never captures everybody.
Of course, I’m almost certain the Dodge Charger, like all other cars, is full of processors with tons of code. The fuel mixing system that gives it its power is computerized in a typical car. One technology “leading the resistance” against another.
This does mean a lot of changes for the automobile industry, as I wrote in my article on car design changes. Today a car’s price is remarkably correlated with its horsepower, which is part of the reason Dodge wants to advertise this way. Even when luxury is the real product, you will still find extra horsepower. This may change as people want comfort in their ordinary car, and only want horsepower in the vehicle they rent for the weekend.
It’s very common to use mobile phones for driving activities today. Many people even put in cell phone holders in their cars when they want to use the phones as navigation systems as well as make calls over a bluetooth. There’s even evidence that dashboard mounting reduces the distracted driving phenomenon associated with phones in cars.
Nokia and others are pushing one alternative for the cars that have dashboard screens. This is called “Terminal Mode” and is a protocol so the phone can make use of the display, buttons and touchscreens in the car. Putting the smarts in the phone and making the dash be the dumb peripheral is the right idea, since people upgrade phones frequently and cars not nearly so much. The terminal mode interface can be wireless so the phone does not have to be plugged in, though of course most people like to recharge phones while driving.
Terminal mode will be great if it comes, but it would be good to also push for a standard port on dashboards for mounting mobile phones. Today, most mobile phone holders either stick to the windshield with a suction cup, or clamp onto the vents of the air conditioner. A small port or perhaps flip out lever arm would be handy if standardized on dashboards. The lever arm would offer a standard interface for connecting a specific holder for the specific device. In addition, the port would offer USB wiring so that the holder could offer it to the phone. This would offer power at the very least but could also do data for terminal mode and some interfacing with other elements of the car, including the stereo system, or the onboard-diagnostics bus. Access to other screens in the back (for playing video) and to superior antennas might make sense. While many phones use their USB port to be a peripheral to a PC, some have “USB to go” which allows a device to be either master or peripheral, allowing more interesting functions.
Even with terminal mode, there could be value in having two screens, and more buttons, though of course apps would have to be developed to understand that. However, one simple thing is that a phone could run two apps at once on two screens (or even two apps at once on the larger screen of the car) which would actually be pretty handy.
While I believe airlines could sell the empty middle for somewhere in the range of 30-40% of a regular ticket, this still has issues. In particular, are they really going to bump a poor standby passenger who had a cancelled flight and make them stay another night so that people can get a more comfortable seat?
One idea is to allow the sale of empty middles by dutch auction. In effect this would say, “If there are going to be empty middles on this plane, those who bid the most will get to sit next to them.” If this can be done, it’s a goldmine of extra revenue for the airline. What they sell costs them nothing — they are just selling the distribution of passengers on the plane. If the plane fills up, however, they sell it all and nobody is charged.
The dutch auction approach would let each passenger make an offer. If there are 5 empty middles, then the 10 people who sit next to them win, but they all pay the 10th highest bid price. If only 9 passengers bid, the 10th highest price is zero, and everybody pays zero — which is what happens today, except it’s semi-random. While this may seem like a loss for the airline, many game theory tests suggest that dutch auctions often bring the best result, as they make both sides happy, and people bid more, knowing they will actually pay the fair price if they win.
(On the other hand, airlines are masters at having two people pay vastly different prices for exactly the same thing and have managed to avoid too much resentment over it.)
There is one huge problem to solve: How do you arrange that matched bidders are sitting together to share the empty middle? Each empty middle benefits two passengers. read more »
First of all, the TED talk given by Sebastian Thrun, leader of the Google self-driving car team (disclaimer: they are a consulting client) is up on the TED web site. This is one of the short TED talks, so he does not get to go into a lot of depth, but notable is one of the first public showings of video of the Google car in action on ordinary city streets. (The first was at PodCarCity, but video was not made available on the web.)
At TED the team also set up a demonstration course on the roof of a parking lot, and allowed some attendees to ride and shoot videos, many of which are up on the web. While the car does perform well zooming a slalom course, and people have a lot of fun, the real accomplishment is what you see video during the talk.
Another “City of the future” video has appeared featuring robocars prominently. This Shanghai 2030 video plays out a number of interesting robocar aspects, though their immense elevated road network reminds me more of retro futurism. A few things I think will be different:
The people in the car sit side-by-side. I think face-to-face is much more useful. It’s more pleasant for conversation, and it allows for a narrower car which has huge advantages in road footprint and drag. Some people can’t stand facing backwards, and so there will still be side-by-side cars if you have two people like that, but I think a large fraction of cars will move to face-to-face, either narrow (for 2) or wide (for 3 or more.)
The video shows cool displays projected onto the windscreen. This “heads up” sort of display makes sense if you have to keep your eyes on the road while using the screen, but in these cars, the people don’t. On the other hand it’s true that some people get motion sick looking down while riding, but you can also put an opaque screen in the middle of the window in a robocar.
It’s National Robotics Week with lots of robot related events. In the Bay Area on Thursday, an all-day robotics demo day for kids and adults will take place at Stanford’s robotic car lab, so people will get a chance to see Junior and other Stanford robocars there.
The trend continues — last year U.S. road fatalities dropped again to 32,788. That’s a steady decline since over 43,000 5 years ago. And this is in spite of total vehicle miles going up. As a result, the death rate per 100 million miles is now 1.09, the lowest it has been in 60 years.
That’s very good news, though many forces fight for the credit. The leading contender seems to simply be that cars are getting safer in crashes, with better crumple zones and air bags, and more people wearing seatbelts. Medicine has also gotten better. Some will also be coming from better cars with safety systems like anti-lock brakes, crash-warnings and lane-departure warnings — precursors to robocar technology — but it would be wrong to assume these are a big component. Also worth noting that this happens in spite of the rise of people talking and texting while driving, though the secretary gives some credit to the recent laws banning this. But that doesn’t explain why the drop began in 2005.
It’s also odd that while fatalities drop almost everywhere, they’re actually up in New England by 18% and by 4% around the midwestern Great Lakes, and generally up around the north-east.
Google took its car down to the TED conference in Long Beach and did a few demo drives for people. In this mashable story you can catch some videos, inside and outside, of the car driving around a cone-based course on top of a parking lot near TED.
Toyota recently released a video with a vision of future transportation, including lots of self-driving cars in a city of the future. This short animated video has trucks in platoons and call-on-demand cars that come to your location and drive you around the city, or let you disengage and self-drive outside the automatic lane. In Toyota’s city there are special lanes which have guide markers and also inductive powering of the electric cars. While the powering may be valuable, I believe that the special infrastructure vision is an old one, and there are already several demonstrations of driving on existing roads without modification.
Once such demonstration comes from the “Made in Germany” team which certainly likes to come up with demos to attract attention. In this case they combined a headband that reads EEG/EMG signals with the controls of their robocar for what they call Brain Driver. The car does most of the driving, but signals from the headband can be used to tell it to go left or right at intersections, or accelerate and brake. My general experience of such EEG headbands has indicated that getting 5 unambiguous signals like that quickly is a tough job from pure EEG, so I am curious if they added some EMG (muscle) to it.
The brain driver is just a demo, but it does show one interesting technology, which is the ability for robocar technology to allow a vehicle to be driven through a very, very simple user interface — ie. just a few buttons or a joystick. I suspect that for people so disabled that they can only communicate via EEG — that’s majorly disabled — it will be better to wait for a full robocar technology that doesn’t require any human input for the driving part.

I learned a while ago about one approach to this plan, a new “cuddle class” from Air New Zealand also known as the skycouch. It’s a row of 3 coach seats that folds down into a very narrow and short bed for two. The idea is that couples can book the whole row for 2.5x the cost of one seat, ie. the empty middle is being sold at a pretty reasonable half-price, or 1/4 price per person.
As I noted earlier, that alone would be worthwhile. Many people would gladly pay 25% more for an aisle or window with a guarantee that nobody was in the middle, and would get together with other solo voyagers to do this. Air New Zealand has for some time offered what it calls the “Twinseat” which is the ability to buy (for a fairly low price around $60) an assured empty adjacent seat “subject to availability.” This is something different — it’s simply saying that, if there are going to be empty middles on the plane anyway, the people who pay more at the gate will get those next to them. You can’t assure it on a flight unless you make sure you take a flight that won’t fill up.
This skycouch seat however has armrests that really go all the way up, and a footrest that comes up to make the whole thing a platform. Frankly, since 3 seats is only 4.5’ long and the bed is narrower than a twin bed, you need a couple that sleeps together very comfortably while spooning. While everybody likes doing that for a little while, it’s fewer who can do that for a whole night. One person could buy the whole row, I guess, but at 2.5x it starts to approach a nice business class seat, many of which now lie flat. (Mind you I’m picky enough that I don’t sleep that well in the business class flat seats, and I have yet to want to pay for the 1st class ones.)
It’s nice to the see the innovation, though. I mean some airlines even have coach armrests that don’t go up all the way when reclined, and that’s a real pain for couples who want to relax together even in the old seating designs.
What would be more interesting, if less romantic, would be a way to have a portable platform that could be installed on top of this row to turn it into two bunkbeds. From a physical standpoint, you could have 4 slots for poles, some reinforcing straps to form X braces on the poles, and a board with inflatable mattress on the top, such boards packed somewhere compactly in the ceiling when not in use. The poles would have to go up and hold a net and bars to stop the top bunkmate from falling out. But the hard part would be making this strong enough to qualify as safe in an emergency landing, since an emergency might arise while these are still assembled, though they would all be dismantled well before landing and they would only be used on flights 10 hours and up. If there were a section of these you could help it along by having no recline in these seats so the seat backs are solid and able to support the upper berth.
In this case, you could have strangers happily paying 125% of the base ticket price for one of these bunks. Lot of work to set up and tear down, though. Probably need a weight limit in the upper bunk. If you can do it at all.
A release from the National Federation for the Blind reports a blind person driving and avoiding obstacles on the Daytona speedway. They used a car from the TORC team at Virginia Tech, one of the competitors in the Darpa Grand Challenges. In effect, the blind driver replaced the “drive by wire” component of a robocar with a more intelligent and thinking human also able to feel acceleration and make some judgements. As the laser and other sensors in the car detected obstacles and turns, the computer sent audio and vibratory signals to the driver to turn, speed up or slow down.
While this demo is pretty simple, it was part of a larger project the NFB has to encourage computer and robotic technologies to let the blind do what the sighted can do. In my robocar roadmap I outlined a number of bodies who might promote and lobby for robocar technology, in particular the blind, so it’s good to see that step underway. They did it as well in 2009 with a simpler dune buggy.
This car did not use the fancy and expensive 64 line Velodyne LIDAR sensor that has become the norm on most other working robocars. The Virginia Tech team (Victor Tango) was the only one of the 6 teams to complete the urban challenge not to use that LIDAR. The car shown isn’t nearly as decorated with sensors as Victor Tango was, at least from looking at it visually, indicating good improvements in their system.
Last year I wrote about an interesting but simple pedal powered monorail/PRT system called Shweeb which had won a prize/investment from Google. Recent announcements show they are not alone in this concept. Scott Olson, the original developer of the Rollerblade, has founded a company called Skyride Technologies to build their own version of a pedal powered suspended monorail.
You will find much that is similar between the two concepts, though they were developed independently. I will have to give Skyride the nod of picking names, though. Skyride offers both pedaling and a rowing-machine style interface, the latter aimed both at the disabled and those seeking a different kind of workout.
At present, the Skyride car is also open to the air, which has both advantages and disadvantages when it comes to cooling, drag, and exposure to the elements. Skyride does not also seem to offer the “bumper” system in the wheel cartridge which Shweeb claims will allow vehicles to safely hit one another and then push one another in trains.
Both are confined to prototype tracks for now, though the Schweeb one is an amusement ride that is open to the public. Both have plans to solve the most important problem in turning this into a real transportation system for campuses or urban areas, namely a switch that lets the vehicle smoothly and safely change tracks. Switching has always been an issue in monorails — not that it can’t be solved, but it’s just a little harder than changing lanes in a car. Rail systems sometimes put the switching in the track (that’s what regular heavy rail does) but that’s not very practical if you are going to have very frequent small vehicles. You want in-vehicle switching but with no risk of derailing.
While this concept is interesting, and even more fun if they can prove it works and then add some automation, I am not sure it will ever become a really big space. Still, having 2 companies will not doubt spur a bit more innovation.
