Automated Traffic Signal Performance Measures (ATSPM) are a series of visual aids that display the high-resolution data from signal controllers. They are a valuable asset management tool, aiding personnel in the control of both signal hardware and signal timing and coordination. They allow analysis of data collected 24 hours a day, 7 days a week, improving the accuracy, flexibility, and performance of signal equipment and the system as a whole. ATSPM are used to optimize mobility, manage traffic signal timing and maintenance, reduce congestion, save fuel costs and improve safety.

This is the repo for ATSPM v4.3 and below which has now been depricated. The repo for ATSPM v5 and future development can be found here: https://github.com/OpenSourceTransportation/Atspm

ATSPM

Starting in 2002, Purdue University and Indiana DOT developed a partnership to evaluate the effectiveness of various vehicle detection devices. The result was a published standard in 2012 that defined traffic signal controller event codes, several key metrics, and charts that established the fundamental traffic signal performance measures. From this, Utah DOT developed this open source (Apache V. 2.0) software to automatically visualize these metrics and charts to show traffic engineers how their signals are performing in real-time and thus ATSPM was born. Data metrics include vehicle volumes, arrivals on red, pedestrian delay, split failures, and many more.

It's possible this software can be configured for other agencies to use.
