CDOT Chicago Centralized Transit Signal Priority (CCTSP)

Description

This project will implement a centralized Transit Signal Priority (TSP) system that will serve CTA buses with signal priority requests that are sent through the CDOT Traffic Management Center (TMC) and transmitted to traffic signals in real time. This will include installation of new hardware and software for both the CTA and CDOT that will require integration to deliver timely responses at corresponding traffic signals for centralized TSP requests made by CTA buses along the following corridors: Roosevelt Road from DuSable Lake Shore Drive to Western Avenue; Stony Island Avenue from 57th Drive to 95th Street; and Broadway–Sheridan Road between Hollywood Avenue and Devon Avenue.
