A Stop Based Approach for Determining When to Run Signal Coordination Plans

This paper presents a stop based approach for determining when to run signal coordination plans based on the traffic volume. A stop based model is developed to predict the probability of making more than a certain number of stops while vehicles travel along an arterial during the actuated operation of signals. To determine when signals should go into coordination, two thresholds need to be established: the desired number of stops and the probability of desired number of stops. Through establishing the aforementioned thresholds, the level of traffic volumes in which coordination plans should be on are obtained. The application of the proposed model is showcased through a real case example study. Finally, a survey is conducted on when U.S. traffic agencies implement signal coordination plans. The results of the survey reveal that agencies use 250 vphpl up to 500 vphpl as a minimum level of traffic volume to trigger signal coordination plans. Considering the stop based model and the traffic volumes that these agencies use, it is revealed that the traffic agencies tend to establish a relatively low threshold for the desired number of stops.
