How much of a green light do you need?

We've known for a couple of decades that optimizing street light systems can made a significant difference in congestion levels, and also reduce emissions and other side effects of congestion. But a new report from Institute of Transportation Engineers shows that of the nation's traffic agencies surveyed: 68% said they have either no documented management plan for their traffic signal operation, or their plan is to simply respond to problem intersections as they happen. 71% don't have staff to monitor traffic before and after normal working hours. 57% said they don't conduct routine reviews of traffic signals within three years. A USA Today article on the report here. The full report is supposed to be available here today.
