Traffic signal management systems have been proven to demonstrate significant benefits from the coordination of traffic signal operations. However, with the continued growth of the various urban areas in the Metro Vancouver area and the installation of an increasing number of signalized intersections, there is a growing need to coordinate the traffic signal operations between adjacent municipalities and agencies. The goal of the Integrated Regional Signal System (IRSS) program is to make better use of available information and communications technologies to provide a 'system of systems' that facilitates coordinated operation between individual municipalities and jurisdictional agencies, while also allowing the individual agencies to maintain their autonomy with respect to signal control equipment selection and signal timing plan implementation. This paper will present an overview of the IRSS operations and summarize the results of the 'before and after' studies with a focus on the benefits including the estimated GHG reductions attributed to improved signal coordination.
