Session Title
Measuring Performance of Traffic Signal Operations and Signalized Arterial Corridors
Track Title
Traffic Operations
Event Description/Abstract
Automated traffic signal performance measures (ATSPMs) are being deployed with increasing frequency. This session presents a method of evaluating corridor performance at the system level using high-resolution data. This method develops five subscores for the areas of communication, detection, safety, capacity allocation, and progression; these are given a letter grade based on quantitative performance measures, with context-appropriate scales. An aggregate score for each corridor is determined using the lowest subscore of each of the five areas.
