Real-Time Traffic Control for Urban Environments: Expanding the Surtrac Testbed Network
Abstract
Surtrac is an intelligent, real-time, adaptive traffic signal control system designed specifically for operation in urban (grid) road networks. It has been deployed on a 9 intersection pilot site in Pittsburgh, Pennsylvania since June 2012, and an evaluation study has confirmed substantial reductions in travel times, number of stops and emissions reduction. Based on the success of this pilot, the initial deployment has now been expanded to incorporate 9 additional intersections, with plans in place to expand incrementally to 49 intersections by early 2015. This paper describes the ongoing expansion of the Surtrac pilot test deployment and summarizes the results of a recently completed study to assess Surtrac performance on these 9 new intersections. The evaluation shows substantial reductions in travel times and emissions over pre-existing conventional signal control (essentially mirroring the results achieved on the original 9 intersections), providing further evidence of the positive impact that adaptive traffic signal control can have in complex urban settings.
