Abstract:Agencies that operate traffic signals now have an emerging tool to help them succeed in their day-to-day operations. The availability of high-resolution traffic signal data along with analysis tools has enabled these agencies to troubleshoot problems very quickly before they escalate into bigger issues and to maintain and update signal timings in a proactive manner. This methodology is achieved by using tools called automated traffic signal performance measures (ATSPMs) or signal performance metrics. Currently, signal maintenance and operational issues are reactively identified through public feedback, and there could be a significant lag between problem occurrence, troubleshooting, and implementation of a corrective measure, causing public dissatisfaction. Agencies wanting to implement ATSPM systems need to have a good understanding of the requirements of the system. This report also provides detailed functional and technical requirements to support the development of formal specifications to procure an ATSPM system. These requirements are then coupled with guidelines for the local agencies. These guidelines start with identifying champions in the agency that will encourage the use of the system, assess the available resources, which include infrastructure, personnel, and financial resources, suggest prioritization of available resources to maximize the benefits of an ATSPM system, and finally recommend a step-by-step strategy to implement and operate the system.
