[0042] Such as figure 1 As shown, a highway VMS layout optimization method based on road network classification, the method includes the following steps:
[0043] (1) Classify the road network to be laid out, including national-level road network and inter-provincial road network. The road network uses toll stations as network nodes to connect various expressways in the province;
[0044] (2) Analyze the national-level road network and the inter-provincial road network separately, and use the road between network nodes in each road network as a road section to obtain the traffic data of each road section and the criticality of the road section, and design the traffic data in this process (OD data) processing, manage OD data in different levels of road networks: national OD management, inter-provincial OD management, line OD matrix extraction. Such as figure 2 Shown is the flow chart of specific OD data processing. The inter-provincial OD matrix is obtained from the data ...
