Performance-Based Management of Traffic Signals

The objective of the research is to develop guidance for agencies across the spectrum of resource levels to implement a performance measurement approach to traffic signal management. The guidance should describe how traffic signal performance metrics could be beneficially incorporated into agency processes and, to the extent practical, the benefits and cost savings that result, such as: (1) Organizational. Reporting on system performance and agency accountability to executives, governing bodies, and the public. (2) Planning. Identifying and prioritizing locations for geometric and signal improvements (including those for pedestrians, bicycles, transit, and freight); providing complete intersection approach volumes and turning movement counts throughout the year; using safety surrogates (e.g., reducing red light running, reducing arrivals on red) to estimate safety benefits; and using performance data to estimate benefits to traveler delay, travel time, and travel time reliability. (3) Design and Construction. Determining the impacts on travelers of various maintenance-of-traffic alternatives. (4) Operations. Reducing complaint calls due to the public perceiving improved operations, providing readily accessible information to address the remaining complaint calls, reducing the need to model signal operations, validating microscopic simulation models for analyzing alternatives, and managing agency tort liability due to better data on signal operation. (5) Maintenance. Identifying failed hardware and estimating resources needed for repair and reducing call outs.
