MODELLING PRIORITY SHARING AT UNSIGNALISED INTERSECTIONS

The traditional gap acceptance theory of unsignalised intersections is based on the assumption of absolute priority to major stream vehicles. However, it has been found that priority sharing exists in reality. Priority sharing at unsignalised intersections was modelled microscopically using four different merging strategies to describe the gap acceptance process. Simulation studies were carried out to identify the most likely case among the four possible strategies. It was found that only the limited priority system could well represent the merging process which was observed in the field during congested periods. (a)
