Traffic Optimization Countermeasures of Intersection Near Urban Expressway Ramp-Taking the Intersection of Zhaojun Road and Nanerhuan Road in Hohhot as an Example

Urban traffic can be improved a lot when expressways are constructed. However, congestion may be a problem for the intersections near expressway ramps. The intersection of Zhaojun Road and Nanerhuan Road in Hohhot was taken as an example, and traffic optimization countermeasures of intersections near expressway ramps was investigated in this paper. Firstly, traffic volume and signal timing of this intersection were surveyed and the existing problems were analyzed. Then, some optimization countermeasures about traffic management and intersection design were proposed. Finally, the optimization scheme was evaluated through VISSIM simulation. Traffic at intersections near expressway ramps can be improved through ramp exit management, parking line design, pedestrian safety island and bus-only approaches.
