Abstract:

The main focus of this paper is to develop gap acceptance probabilistic models for two-wheelers at three-legged unsignalized intersections in India. Unsignalized intersections are controlled with the help of stop or yield sign in developing countries, but in India, sign do not work. The processing of vehicles at unsignalized intersection is complex and very interactive, whereby each driver makes individual decisions about when, where, and how to complete the required maneuver. Such intersections cannot be analyzed based on the finding of the unsignalized intersections in other countries (HCM 2000, for example). This paper systematically analyzes the behavior of right turning two-wheelers at uncontrolled intersections. Data on gap acceptance behavior is obtained with Video. The various parameters that are collected include vehicle arrival rate, gap accepted/rejected, time to cross the intersection, driver's gender and approximate age, type of vehicle, and vehicle occupancy. The critical gap by Raff method for two-wheelers is found to be 2.5 second. This is value is smaller than the critical gaps reported in other studies. Probit and Logit models are developed using NLOGIT 4.0 that estimate the probability of accepting a given gap based on various drivers and traffic attributes. For model calibration, 80% of the extracted data is used and remaining is used for model validation. The percent correction prediction by both models for validation data is greater than 80%.
