Recently, traffic jams are becoming more and more frequent in many big cities of China in the joint section of the freeway on/off-ramp and its adjacent intersection with the increase of vehicles. Even more serious, the traffic jam at traffic nodes will spread towards larger areas. This paper discusses some traffic problems of a typical on-ramp of an elevated expressway with an adjacent intersection. On these bases,asignal control scheme of the intersection and some traffic management measures are proposed to ensure that the on-ramp is unblocked and to increase the capacity of the on-ramp joint. By simulation of Vissim, the improvement measures proposed are proved to be effective. The research results can provide reference for construction of freeways and the urban intelligent traffic management system.
