Real-Time Traffic Signal System Performance Measurement

Real Time Signal Performance Measurement DiagramTransportation professionals measure traffic signal system to improve efficiency and reliability of roadway network. Traffic signal performance measurement and visualization provide insights as operational tools to help traffic management center get more benefits from infrastructure investment. The primary objective of the research is to identify and develop metrics, guidelines, and deployment strategies necessary to conduct real-time monitoring of traffic signal performance based on existing and planned infrastructure resources and the New Jersey Department of Transportation (NJDOT) needs. This research is especially important for New Jersey (NJ) with the deployment of Adaptive Traffic Signal Performance Measurement (ATSPM) and the establishment of the Arterial Management Center (AMC). This study’s primary objective is twofold: 1) how to utilize existing field data and equipment to establish Signal Performance Measures (SPMs) for real-time monitoring, and 2) what additional data and equipment may be employed to generate additional SPMs while automating the real-time traffic signal monitoring process. The study included a review of the literature and best practices, several stakeholder meetings, recommendation and development of performance metrics, system architectures, data management, and strategies for deploying RT-SPM systems using existing and planned NJDOT arterial infrastructure and technologies.
