Problems solved by technology

[0007] 1. The relative relationship of the ground features in the road base map is inaccurate;
[0008] 2. On the same road section, the road base maps drawn by different personnel are not uniform, which brings certain difficulties to the judgment of the party responsible for the accident;
[0009] 3. Paper road base maps are not easy to save, archive, and transmit and share information;
[0010] 4. Limited by the on-site drawing time, the road base map is relatively random and incomplete;
However, due to the complex road conditions on site, it is difficult to find a directly corresponding road model, and the road base map still needs to be drawn on site

Embodiment 1

[0200] A road base map information processing method suitable for rapid traffic accident processing, comprising the following steps:

[0201] 1) collect the basic road coordinate information through the total station, and send it to the computer;

[0202] 2) The computer generates the basic road base map symbol information according to the road base map generation method, and performs connection drawing to generate the road base map.

[0203] The method for generating the road base map is specifically as follows:

[0204] 1) Establish a road base map symbol information database;

[0205] 2) Set the corresponding attribute value for each base map symbol in the road base map symbol information database, and store the attribute value information;

[0206] 3) Set the positioning method for each road base map symbol;

[0207] 4) Determining the exchange data for each road base map symbol, the exchange data includes the code of the symbol, the location information of the symbol a...

example 2

[0227] Take the intersection of Siping Road and Zhangwu Road in Shanghai as an example. The intersection is small, and the observation elements include street lights, signal lights, trash cans, markings, etc. The observation data are as follows:

[0228]

[0229]

[0230] Plotting results like Figure 10 shown

example 3

[0232] Take the intersection of Beijiang Road and Bridge on Zhenjiang Road in Shaoguan City, Guangdong Province as an example. Since there are no traffic lights installed at this intersection and there are many vehicles passing through it, it is a traffic accident-prone area. A total of 275 field measurement points at the intersection were collected, mainly including: road sidelines, lane lines, pedestrian crossings, isolation belts, diversion belts, etc. The observation data are as follows:

[0233]

[0234] Plotting results like Figure 11 shown.

Abstract

The invention relates to a road base map information processing method applicable to rapid traffic accident disposing. The road base map information processing method comprises the steps of: 1) collecting coordinate information of a base road through a total station, and sending the coordinate information to a computer; and 2) generating base road base map symbol information according to a road base map generating method by the computer; and connecting by drawing, thereby generating a road base map. Compared with prior art, the road base map information processing method applicable to rapid traffic accident disposing has the advantages of being beneficial to shortening traffic accident disposing time, high in mapping accuracy, complete in data coverage and the like.

Description

technical field [0001] The invention relates to a road base map information processing method, in particular to a road base map information processing method suitable for rapid traffic accident processing. Background technique [0002] According to the national standard "GBT11797-2005 Road Traffic Accident Scene Graphical Symbols", the graphic symbols of the traffic accident scene diagram are shown in Table 1. It can be seen from the table that traffic accident scene diagrams are divided into six categories: graphic symbols of traffic elements, graphic symbols of dynamic traces, graphic symbols of traffic scenes, graphic symbols of roads and road safety facilities, graphic symbols of land use, vegetation and features and other graphic symbols. According to different drawing stages, these symbols are divided into on-site element graphic symbols and road base map graphic symbols. The road base map graphic symbols are relatively fixed and do not change according to the occurre...
