Chong improves system for timing of urban lights to minimize commute times


July 17, 2014

A new optimization process developed by Carolina Osorio, an assistant professor of civil and environmental engineering at MIT, and graduate student Linsen Chong can time traffic lights in large urban areas while accounting for the complex and diverse reactions of individual drivers. Their approach uses high-resolution traffic simulators that describe, in detail, the behavior of drivers in response to changes in travel conditions. In detailed simulations of Lausanne’s traffic, they found that the timings produced by their approach reduced the average travel time for commuters by 22 percent, compared with timings generated by commercial traffic-light timing software.
