PACE Bus Transit Signal Priority Plan for Chicagoland and Suburbs

Pace Suburban Service is pursuing Transit Signal Priority (TSP) as traffic control strategy to modify the existing infrastructure and traffic signal control system to provide priority to Pace buses at much lower costs. This paper discusses the process by which TSP deployment is prioritized for Pace’s Fixed Route Network. The project included analyzing approximately 850 miles of roadway along 27 potential TSP corridors to allow the Pace to identify the areas of greatest need for future TSP funding and deployment. The methodology used to prioritize TSP Corridors follows three main steps: 1) The collection of traffic and transit data, 2) the assembly of all data in GIS and Microsoft Excel to visually display and analyze the information, and 3) the prioritization of TSP Corridors based on all the transit and traffic data collected. Since these conditions vary along the length of each TSP Corridor, the TSP Corridors were divided into one-mile segments. The second step involved the assembly of the data into a GIS database and a Microsoft Excel database for further analysis in the prioritization of the 27 TSP Corridors. The prioritization of segments of TSP Corridors was the final step in the methodology. Three different scenarios were presented that account for changing conditions with respect to funding and levels of transit service. The prioritization results provide the transit agency with a mile-by-mile analysis of where the greatest need exists for TSP deployment along each of the 27 TSP Corridors.
