[Abstract]:Urban road network zoning refers to the selection of one or more paths to divide the whole urban network into several traffic areas according to the road network structure and traffic flow characteristics. In order to improve the operational efficiency of the road network, scholars at home and abroad have done a lot of research on the problem of road network zoning and achieved a lot of results. The existing research does not discuss the problem of road network partition based on congestion. Therefore, this paper considers that any section of road is likely to be blocked. From the two angles of network topology anti-blocking ability and road network traffic equilibrium distribution anti-blocking ability, this paper puts forward the measurement index of road network zoning effect, and takes the optimal zoning effect as the goal. The optimal partition path selection model and the optimal partition path combination model are established and solved. The main work and results of this paper are as follows. An optimal partition path selection model and an optimal partition path selection model based on the anti-blocking ability of road network topology are established. Combine the model and solve it. In the case where any section of the road network is likely to be blocked, The ratio of the shortest alternative path length to the shortest path length before blocking is used to measure the anti-blocking ability of the road network topology structure, and then from the point of view of the change of the anti-blocking ability of the road network topology structure before and after the partition. The index of the effect of road network zoning is proposed, which is the variation factor of the anti-blocking ability of the area based on the network topology, that is, the ratio of the average anti-blocking ability of the k sub-region to the anti-blocking ability of the whole road network under the topological structure. Aiming at the optimal partition effect, the optimal partitioning path selection model and the optimal partitioning path combination model are established to divide the urban road network into two and k sub-regions, and an effective algorithm is designed to solve the problem. In this paper, the optimal route selection scheme and the optimal partition path combination scheme are given. The model and algorithm are used to analyze the local road network in Yuzhong District of Chongqing City. The optimal anti-jam ability based on the traffic equilibrium distribution of the road network is established. The partition path selection model and the optimal partition path combination model are solved. The ratio of the total travel time of the road network to the total travel time of the road network before blocking is used to measure the anti-jam ability of the road network based on the traffic equilibrium allocation. Then, from the point of view of the change of anti-blocking ability of road network traffic equilibrium allocation before and after the partition, the paper designs the measure index of road network zoning effect, which is based on road network traffic equilibrium allocation. That is, the ratio of the average anti-blocking ability of k sub-region to the anti-blocking ability of the whole road network before the partition is given under the traffic equilibrium distribution of the road network, and the objective is to optimize the effect of the area. An optimal partitioning path selection model and an optimal partitioning path combination model are established to divide the urban road network into two and k sub-regions, and an effective algorithm is designed to solve the problem. The optimal route selection scheme and the optimal partition path combination scheme are given, and the model and algorithm are used to analyze the local road network in Yuzhong District of Chongqing.
