Surtrac is an innovative approach to real-time traffic signal control, combining research from artificial intelligence and traffic theory. Surtrac optimizes the performance of signals for the traffic that is actually on the road, improving traffic flow for both urban grids and corridors and leading to less waiting, reduced congestion, shorter trips, less pollution, and happier drivers.

Measuring Cruising for Parking

Drivers searching extensively for parking, a behavior known as cruising, leads to excess congestion and pollution. Many recent smart parking interventions have attempted to address this issue, though the problem of effectively detecting and measuring cruising remains largely unsolved. We are developing solutions to detect and measure the frequency of cruising for parking and its effects on congestion.

Measuring Performance of Urban Traffic Signal Networks

We are building technologies to measure system performance of surface road networks, particularly dense urban networks. This technology could be used for performance measurement of traffic signal systems or roadway infrastructure improvements, congestion detection for traffic management systems, discovery of OD pairs for planning purposes, and other applications.
