Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the prior art, using ArcGIS software and graph theory knowledge, based on regional boundary control, firstly provides a specific plan for border distribution, on this basis, combined with actual intermodulation requirements, planning other Point location, a method of laying out traffic survey sites on ordinary roads considering regional boundary control is proposed, which can be used to arrange traffic survey sites on ordinary roads and obtain traffic volume data, so as to overcome the theoretical basis of traffic surveys on traditional ordinary roads Insufficient, data cannot be considered as a whole

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...

Abstract

The invention discloses a method for laying out ordinary highway traffic situation survey sites considering regional boundary control, which includes the following steps: 1) Simplifying the road network layer in ArcGIS software to obtain a basic route map; 2) According to the road network and Establish boundary control traffic survey points at the intersections of regional boundaries; 3) Based on the distribution of boundary control traffic survey points, add new survey points at specified distances for internal highways in the region to achieve density enhancement; 4) Combine the planned location of points With the existing locations, the planned locations are deduplicated and those within a certain distance from the existing sites are removed; 5) Based on the geographic information system software, the geographical information and road information of the planned locations are generated, and the specific locations of the locations are determined and Adjust according to actual situation. The method described enables the overall site coverage to reach a high level on the basis of regional boundary control and enables the acquisition of comprehensive traffic volume data.

Description

technical field [0001] The invention relates to the field of acquisition of traffic parameter data of common roads, in particular to a method for laying out survey stations of traffic conditions of common roads in consideration of regional boundary control. Background technique [0002] With the continuous increase of traffic infrastructure construction, the construction of my country's ordinary road network is becoming more and more perfect. With the expansion of the general road network coverage, the traffic management and control of the large and complex general road system is becoming more and more important. In order to fully understand and control the operation of ordinary road traffic, all provinces across the country will carry out ordinary road traffic investigations within their respective jurisdictions. [0003] However, at present, from the perspective of the practice of interrogation work, there are many problems in the survey of ordinary road traffic in my cou...
