RTA logo Regional Traffic Simulation with Transit Signal Priority

Study Description

This project will develop and apply a traffic simulation tool to evaluate the regional impacts of deploying transit signal priority (TSP) strategies on multiple bus routes. Phase I of this project wil consist of the development of a regional traffic simulation application that simulates certain street corridors micro-scopically (with user-specified traffic signal timing and bus transit movements for the transit signal priority corridors), while the rest of the road network is simulated meso-scopically. This application will be based upon a micro/meso-scopic simulation/assignment model developed by researchers at Northwestern University and other institutions, called VISTA (Visual Interactive System for Transportation Algorithms). Phase II will consist of the development, simulation, and evaluation of a set of study scenarios that represent various combinations of routes equipped with TSP, congestion levels, and control strategies. The results of this simulation will be used to assess the costs and benefits of various transit signal priority deployment scenarios for both transit and general traffic.
