Wireless system that reduces traffic congestion wins best paper award

At the Intelligent Transportation Systems World Congress last week, CSAIL researchers received one of the best-paper awards for a new system, dubbed RoadRunner, that uses GPS-style turn-by-turn directions to route drivers around congested roadways.

In a comparison with a system developed by Singapore’s Land Transit Authority, RoadRunner yielded an 8 percent increase in average car speed during periods of peak congestion.

“With our system, you can draw a polygon on the map and say, ‘I want this entire region to be controlled,’” says Jason Gao, a CSAIL graduate student who developed the new system with his advisor, Professor Li-Shiuan Peh. “You could do one thing for a month and test it out and then change it without having to dig up roads or rebuild gantries.”
