Traffic Safety in Interchange Intertwined Area Based on Traffic Conflict
The expressway interchanges have functions of rapid,large flow,and multi-directional traffic conversion,which is the key to expressway operation efficiency and safety.This paper collected traffic volume,speed,and other basic investigation data in the interchange intertwined area via UVA to calibrate the parameters of the VISSIM simulation model and simulate the traffic volume trajectory data in the intertwined area.The traffic conflict data were extracted by SSAM software.Finally,the traffic simulation data were analyzed,so as to propose the interchange safety upgrading and transformation measures.
