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.
