Signal Control Method of Misaligned Intersection Considering Turning Radius
In view of the characteristics of the geometric alignment and traffic organization of the urban misaligned intersection,considering the influence of the turning radius on the vehicle operation at the intersection,the relationship model between the geometric parameters and the operating parameters of the misaligned intersection is established through the VISSIM simulation software,and two signal control schemes are proposed.After that this paper takes the misaligned intersection formed by Shuguang South Road-Labor Middle Road-Shuguang Middle Road in Changsha as a case study,and the simulation verification and comparative analysis are carried out by VISSIM software.The research results show that:the driving speed and saturation flow rate will increase with the increase of the turning radius;the driving delay will decrease with the increase of the turning radius;for the misaligned intersection,the coordinated control after reducing the saturation flow rate can reduce the average vehicle delay and improve the capacity and service level of the intersection.
