Abstract
It is of great importance to analyze right-turning behavior at signalized intersection given high accident records related to right-turn vehicles, which also helps provide valuable insights into safety assessment of signalized intersection. This study aims to analyze the right-turn vehicle behavior in protected right-turn phase by considering the influencing factors of geometric characteristics and signal operation. It was found based on empirical modeling results that the right-turn vehicle behavior is closely related to geometric characteristics such as intersection angle and setback distance of stop bar. Furthermore, in order to make a balance of both positive and negative impact, the potential strategies may bring upon safety performance of signalized intersection, all the influencing factors related to right-turn behavior were summarized and evaluated. Finally, the necessity of employing microscopic simulation to enable a comprehensive evaluation of surrogate safety meausure (SSM) at signalized intersection was examined.
