Operations-oriented traffic signal performance measures are important for identifying retiming needs and improving traffic signal operations. Currently, most traffic signal performance measures are obtained from high-resolution traffic signal controller event data, which provides information on an intersection-by-intersection basis and requires significant initial capital investment. However, connected vehicles generate over 400 billion vehicle trajectory points each month in the United States. Through several case studies, explore how high-fidelity vehicle trajectory data can be used to produce traffic signal performance measures such as split-failure, downstream blockage, and quality of progression.
