Study on the Relationship between Tram Stop Location Layout and Intersection Delay Time

［Objective］ In order to improve the operating service efficiency and reliability of trams, it is necessary to study the relationship between the layout of tram stop location and the intersection delay time. ［Method］ By distinguishing the driving characteristics of different vehicles based on the tram operation trajectory data, an average vehicle delay calculation model is constructed when tram stations are set up upstream and downstream at the intersection. Based on the operation trajectory data, the tram arrival time distribution at the intersection is calculated. Then, the expected delays of different types of intersections (traffic flow characteristics, size and scale) are calculated when stations are set up upstream and downstream. ［Result & Conclusion］ A general conclusion is that under certain conditions, it is proper to locate the tram stop upstream at the intersection. In this scenario, the influence of intersection signal timing on tram delay should be considered. It is suggested that the green light on time in the direction of tram travel should be reasonably set according to the time distribution of tram arrival at the intersection area within the signal cycle, so as to reduce the proportion of vehicles long time waiting in front of the stop line, so thus reducing the expected delay. If it is really necessary to locate the stop downstream at the intersection, it is recommended to give priority to the smaller intersections with a relatively high green signal in the direction of tram travel, so as to reduce the increase of tram delay when the stop is located downstream at the intersection.
