Measuring Performance of Traffic Signal Systems Using Existing Detector Technology

Project Description

In this project, TTI examined the issues related to measuring the effectiveness and efficiency of the performance of the signal timing at individual intersections. As part of the project, TTI first identified the measures that TxDOT traffic signal engineers and technicians need to assess the performance of the traffic signals under their jurisdiction. TTI then examined the capabilities and features of the various detection and control systems that TxDOT commonly used at signalized intersections to determine 1) if the performance measures (or a close surrogate) are currently available with the technology, and 2) if not available, how they can be generated using features in the technology.
