Research on Sub-Area Division and State Identification of Urban High-Density Road Network

At this stage, urban high-density road networks have become one of the main modes of urban road network planning and construction. Large-scale traffic congestion may occur within the high-density road network, which leads to the decrease of vehicle operation efficiency within the road network. Taking urban high-density road network as the research object, and considering structural characteristics of urban high-density road network, we built a high-density road network simulation model based on VISSIM; analyzed the road network sub-area dividing and evaluation methods; proposed traffic state-level classification and identification method of road network. The results could provide reference for the development of traffic control strategies at the road network boundary.
