It is urgent to understand the traffic performance by modelling traffic streams under mixed traffic conditions, in which motorcycles contribute to a dominant rate of the total traffic composition. This study aims to analyze the interactions between the left-turn and the opposite straight-through vehicles and estimate the capacity of both flows. An attempt is made to develop a social force model for the vehicles. The result indicates that the social force model is an appropriate approach to model the mixed traffic flow at signalized intersections. The study also outlines various aspects of integrating such a model into the existing methods for microscopic traffic flow simulation and capacity analysis.
