Abstract
In order to optimize the coordinated control of the urban expressway exit ramp and the adjacent intersection, this research analyzes the causes for congestion at the adjacent area between the expressway exit ramp and conventional road. Combining with a relatively common form of elevated road with parallel roads, a coordinated control optimization scheme of expressway exit ramp and adjacent intersection have been put forward. This paper simultaneously analyzes the theory of single point control of intersections, which is based on regular traffic management and control, and an optimization method is offered, The integrated control of expressway and the ground connection area is realized. Finally, a contrast test scheme is designed through VISSIM, and the results show that signal conditioning based on the conventional control can promote expressway exit ramp traffic entering the intersection and travelling more smoothly, which proves the feasibility of the method.
