Advanced Signal Hardware and Timing Using Automated Traffic Signal Performance Measures In Reserve

Automated Traffic Signal Performance Measures (ATSPM) are an emerging technology promoted by the FHWA in the fourth round of their Every Day Counts (EDC-4) initiative. The technology and its benefits are described by the FHWA as "a high-resolution data-logging capability added to existing traffic signal infrastructure and data analysis techniques. This provides agency professionals with the information needed to proactively identify and correct deficiencies." Additionally, the technology once implemented can reduce agency costs on software modelling and manually collected data currently used for signal retiming.

 

Two leaders in integrating the technology are Utah UDOT and Georgia GDOT, with Utah developing a software that is used by both agencies, along with others in the US in the process of implementing.

Why is this a priority and what are the benefits for the State/County/City?

As of the EDC-4 Progress Report #3 released in summer 2018, NJDOT is in the demonstration phase of ATSPMs, installing the technology on Route 202 and evaluating the performance measures it can provide. According to the report, the agency is looking to institutionalize the system throughout the state, with a goal of local agencies developing traffic signal management plans.

With this goal in mind, a study of the agencies that have pioneered the technology can be of use to NJDOT. By conducting an analysis in coordination with UDOT, GDOT, and other early adopters, a report can be developed in order to streamline the integration of the technology statewide. Ideal outcomes of a report would include practical guidance on using the technology day-to-day to identify hardware and timing issues, best practices for wider adoption, and potential roadblocks to implementation and how to mitigate them.
