Micro-simulation study of the effect of median bus lanes with midblock stop on capacity of urban signalized intersection

This paper presents a micro-simulation approach on improving the capacity analysis of an urban signalized intersection impacted by median bus lanes with midblock stop. Four factors that influence the capacity are analyzed. Based on the data from a traffic survey, VISSIM simulation is used to analyze the relationship between capacity influencing factors and the capacity. The Capacity Reduction Factor is calibrated. Then, an improved calculation model on the capacity of the signalized intersection with median bus lanes is proposed. Finally, the result is compared with results obtained from other analytical methods, and validated against field data, which shows that the result obtained by the proposed model is closer to the field capacity with the smallest relative error.
