I recently read it costs about $150,000 to put in traffic lights here in California. That's a heavy duty pole, the lights, the power, the connection to other lights and the vehicle sensors. Seems to me modern technology should be able to make that a lot cheaper. New lights are all LED (the energy savings pay for themselves quickly) but that should also mean smaller safer power lines with special digging under the road. (Wonder if they could do it with light pipes and have no electricity up there.)

This is an "ideas" blog rather than a "cool thing I saw today" blog. Many of the items are not topical. If you like what you read, I recommend you also browse back in the archives, starting with the best of blog section. It also has various "topic" and "tag" sections (see menu on right) and some are sub blogs like Robocars, photography and Going Green. Try my home page for more info and contact data.
