Using Big Data and Machine Learning to Evaluate and Optimize the Performance of Traffic Signals in Tennessee

In the state of Tennessee, thousands of traffic signals covering major metropolitan areas and dotting smaller cities and major arterials are an integral part of the State’s transportation mobility system. Most traffic signals utilize fixed-cycle scheduling and there are no continuing, systematic, and standardized approaches to evaluating and improving their performance; instead, a very small number of traffic signal timing plans are reviewed by consultants only after repeated complaints or unusual crash numbers. This is highly undesirable and has not been addressed so far due to cost, manpower, jurisdiction, and technology issues. This project will address this problem by finding an economical way to evaluate the performance of the traffic signals in Tennessee and identify the most deficient ones that need immediate attention.
