【Abstract】 Based on the macroscopical stable continuous-flow traffic mode and the occupancy adjustment strategy,this paper proposes a coordinated control system of ramp on freeway by using Visual Basic software.The proposed system is then used to simulate the dynamic operation mode of freeway,and the corresponding operation and calculation effectiveness are finally verified by data simulation.The results show that the proposed control system is of good dynamic performance,and possesses the advantages of eliminating traffic jams,maintaining traffic-flow stability and ensuring efficient and safe drive.更多还原
