Lights that indicate free parking stalls
Submitted by brad on Mon, 2012-03-26 23:33Sometimes when I travel I see a great idea that hasn't yet spread everywhere yet. A parking garage I parked at in Tel Aviv had LEDs visible on the roof above every stall. These were red and green if the stall was full or empty. So it was quick to find an empty stall. This probably makes the garage more efficient because people don't have to circle hunting for a spot, and this justifies the cost. (The main cost of these is probably wiring the power for them.)
I've seen studies claiming that in busy areas, up to 30% of the traffic is cars circling looking for parking. Mostly they are looking for free parking or convenient on-street parking, since parking garages, though expensive can usually be found and entered quickly. Indeed, while on-street parking is often much more convenient, in many cases this is an artifact of parking being subsidized (because it's free, or free to people who live in an area) or cheaper than commercial parking markets. But we don't seem ready to fix that, though many cities put restrictions on street and metered parking, limiting the number of hours so that it is in theory only for visitors rather than all-day parkers.
There are many companies trying to see if they can improve parking using mobile devices and the internet. There are companies with sensors that manage parking spaces, companies that let you find spaces on a mobile device and even enter a garage with your mobile device. In some cases you can even extend your parking (if you prepaid) over the phone. Cities have been moving away from traditional meters to things like block meters (where you get a ticket and then put it on your dash) or fancy enforcement vehicles with licence plate cameras that spot not only if you are in a spot too long, but if you move within the busy zone to another spot.
As a user of parking, I would like to know I've got a good spot lined up before I get to my destination, and just pull right into it. I want a competitive market but I don't want to waste time and gas hunting. There are companies trying to address this, though mostly in commercial lots. It's mostly pretty basic right now -- it's considered fancy to even have sites like parkopedia or bestparking with a database of the parking in a city with the prices so you can comparison shop the parking lots.
So now for some rambling on what might be done on street.
