The level of service (LOS) of the non-motorized vehicle at signalized intersection is an important indicator to measure the efficiency and safety of non-motorized vehicles crossing the signalized intersection. The objectives of this study were to identify the factors affecting the LOS of the non-motorized vehicle when crossing the signalized intersection and to develop a suitable method for estimating the LOS of the non-motorized vehicle .The important factors influencing the LOS of the non-motorized vehicle were summarized :turning traffic,through traffic,number of the non-motorized vehicles,and delay. The data collected by video and a questionnaire survey include information on participants’ sense of comfort and safety when crossing the signalized intersection.Delay is the most important parameter,and estimating it accurately is complex because of bicycle and e-bike crossing behavior and mixed traffic condition at signalized intersection.Thus,the delay is the key performance indicator with which to evaluate a signalized intersection’s level of service for the non-motorized vehicles.To evaluate the non-motorized vehicle facilities at intersections for further improvement and better design and construction of further work,LOS is an effective method.
