Abstract: In order to balance the saturation of straight and turn left traffic flow within the same import, and to improve the passable and space-time resource utilization efficiency under single import release mode, the design of the straight-left shared lanes based on utility theory and traffic flow critical model was expounded. According to the field survey of intersection at Wuying Shan road and Huanggang road in Ji’nan of Shandong province, Webster delay model was used to solve the total delay with and without setting straight-left shared lanes under single import release mode. The results show that: the release effect after setting straight-left shared lanes under single import release mode is better.
