Taking the Zhongshanmen Street-Southern Polytechnic Intersection as the research object, based on microscopic simulation technology and traffic conflict technology, the operation efficiency and safety status of the intersection are studied. A VISSIM micro-simulation model for conflict simulation is established, and SSAM software is used to analyze the simulation conflict of the simulation model to verify the rationality of the optimization scheme. The simulation results show that the road service level of the intersection has increased from C to B, and the TTC has also increased from 0.29 to 0.58.
