A Behavioral Modeling Framework of Driver Behavior at Onset of Yellow a Indication at Signalized Intersections

This paper introduces a state-of-the-art Behavioral Model (BM) that can be used as a tool to simulate driver behavior after the onset of a yellow indication until he/she reaches the intersection stop line. The paper presents the proposed general framework of the BM, its components, and discusses its ability to track Dilemma Zone (DZ) drivers and update the information available to them every time step until they reach a final decision. However, for the BM to be able to simulate the driver behavior accurately, information on many variables is needed. This makes it a good tool for testing new signal timings and the DZ mitigation strategies before actual implementation. Also, the BM could be implemented in any traffic simulation software to enhance its modeling capability. The paper attempts to characterize the components involved in the BM framework using data collected form a controlled field driving experiment. However, the model did not show a high success rate which is attributed to the components characterization which would need further effort in order to fine-tune each step in the model. In addition, the paper calibrates a Statistical Model (SM) simulating the driver stop-run decision, which shows a high success rate (82%). It is anticipated, further fine-tuning of the BM components would yield higher success rates.
