Rapid Response: Swiftly Tackling Unexpected Events is Crucial to Keep Traffic Moving

This article examines the benefits of efficient incident management schemes to keep traffic moving when crashes or other incidents occur. It describes several new technologies aimed at spotting incidents more quickly and responding faster. In the United Kingdom, trials are underway to learn whether automated incident detection (AID) systems based on processing CCTV images can more quickly identify stopped vehicles. The author also reports on a program called San Mateo Smart Corridors, located in the San Francisco Bay Area along a 20-mile section of the US 101 where local networks tend to get swamped by vehicles searching for alternatives to the freeway. The program involves signs that guide drivers to alternate routes when there has been an incident. In Des Moines, Iowa, a macroscopic model was used to test a scenario for an incident on a freeway section that caused one or more lanes or just the shoulder to be closed to see the impact traffic would have on nearby arterials. That study led to the development of signal timings that move traffic along more quickly. Finally, the author describes the Southern Traffic Exchange program (STIX) aimed at improving traffic flow following an incident along the I-95 corridor through Georgia, Florida and the Carolinas. It requires the four states to alert one another for lane-closing incidents, special events or major emergencies in order to alert longer distance travelers.
