The purpose of this research is to study how pedestrian crossing timing should be considered in coordinated signal operations. A practical guideline needs to be developed to determine when accommodation (A) of pedestrian timing into coordination is preferable over non-accommodating (NA). With this guideline, practitioners input cycle length (C), volume (v), required pedestrian timing (RPT), and other signal parameters. The guideline will lead to a recommendation on whether A or NA should be used based on arterial vehicle delay. As part of the guideline development, a mathematical model was developed and validated by simulating 3,456 scenarios in VISSIM traffic simulation. Then, a software tool was created based on the mathematical model, named PeTASC (Pedestrian Timing Accommodation into Signal Coordination). A link is provided to download this free software. PeTASC can be used as a reference for an appropriate pedestrian timing design. This software can help practitioners design a better coordination plan and as a result, reduce arterial delay.
