Embodiment
[0035] This embodiment provides a method for laying out sites for investigation of traffic conditions on ordinary highways considering regional boundary control. The flow chart of the method is as follows figure 1 As shown, the following is a detailed description of the layout method of the above-mentioned ordinary road traffic survey site considering the regional boundary control in combination with the ordinary road network of Guangdong Province, including the following steps:
[0036] 1) Simplify the road network layer in ArcGIS software to obtain the basic road map;
[0037] In actual roads, a section of national and provincial highways is generally two-lane parallel, and the field attributes are uplink and downlink respectively. Some special road sections only have one side, and the field attributes are two-way driving sections. According to the concept of graph theory, the graph formed at this time is a directed graph, most of the adjacent nodes are connected to each oth...
