Improving use of technology to reduce traffic congestion
Crashes, lost loads, and other unanticipated highway obstructions quickly can lead to traffic congestion and reduced safety. Technologies such as variable message signs and radio traffic reports can help to notify drivers of problems ahead of them.
In Michigan, the Department of Transportation wants to find out how well residents understand these messages. The Department also wants to know whether these messages help drivers comply with state traffic incident management laws, such as a law requiring drivers to move their vehicles away from a lane with a stopped emergency vehicle.
