Software Speeds Response To Road Accidents

Posted by kdawson on from the fluid-like-no-other dept.

coondoggie alerts us to research out of Ohio State University that could help authorities respond to car accidents more quickly and ease traffic back-ups at lower cost, particularly in rural areas. The software improves the efficiency of communications from in-road vehicle detection loops to transportation engineers monitoring conditions in order to improve traffic flow. Faster response to accidents and traffic jams could have huge payoffs: a 2002 study estimated that traffic jams cost the average city almost a billion dollars a year.

Based on the real speed of the traffic (as detected by this software), subtract 20 mph- and light up the variable minimum speed limit signs with that speed limit. This would then allow the police to actually enforce a minimum speed limit; you could even have radar detectors in the signs that take a digital picture and transmit to cops waiting down the road for the "slower".

      Your second comment shows the problem with changing the maximum speed limit to slow traffic in changing conditions: nobody follows it anyway.

      To be effective, you would want to lower the limit some distance *before* the bottleneck to lessen the rate that new cars came in to the affected area. This means that you would be changing limits on areas that don't appear to most drivers to have a traffic problem. In my experience, most people don't slow down until they absolutely have to - even when they can see stopped traffic up ahead. Since they are probably speeding in the first place and can't see why they have to slow down, they probably won't, and the problem doesn't go away.

Unfortunately, no one pays attention to the sign and keeps on speeding ahead in the left lane. When they get to where the lane ends, there's a huge jam as everyone has to merge over at the last minute.
