The present invention relates to a kind of road base map information processing method being applicable to rapid transit accident treatment, comprise the following steps: 1) gather basic path coordinate information by total powerstation, and send it to computing machine; 2) computing machine is according to road base map generation method formation base road base map symbolic information, and carries out connection drafting, generates road base map.Compared with prior art, the present invention has and is conducive to shortening that traffic accident treatment time, mapping precision are high, data contain congruent advantage.
Description
Technical field
The present invention relates to a kind of road base map information processing method, especially relate to a kind of road base map information processing method being applicable to rapid transit accident treatment.
Background technology
According to GB " GBT11797-2005 traffic accident situ map pictograph number ", the graphical symbol of traffic accident scene diagram is as shown in table 1.As seen from the table, traffic accident scene diagram is divided into 6 large classes: traffic element graphical symbol, moving state tracks graphical symbol, traffic scene graphical symbol, road and road safety facility graphical symbol, Land_use change, vegetation and atural object graphical symbol and other graphical symbols.According to the difference in the stage of drafting, these symbols are divided into live element graphical symbol and road base map graphical symbol, wherein road base map graphical symbol is relatively-stationary, and disobey the generation of accident and change, the figure comprising road base map graphical symbol is called road base map by us.
Table 1
Road base map is the important component part of traffic accident scene diagram, and road content is many, the time of drawing is long.In traffic accident treatment process, the drafting of road base map mainly contains three kinds of modes: 1, schematic diagram is directly drawn in scene, the apparatus measures such as general employing tape measure or stadimeter, specify the position relationship of point-to-point transmission by the mode of dimensioning, such drawing is difficult to the requirement of the measuring accuracy meeting scene of the accident confirmation of responsibility; 2, on-the-spot draw scale map, this operating type speed is excessively slow, particularly its roads of crossing of some Frequent Accidents and affiliated facility, identifier marking all more complicated, so direct speed affecting traffic recovery; 3, draw scale map in advance, preset road base map is called at scene, and the advantage of this mode is that speed is fast, and mapping accurately.
At present, in scene of a traffic accident process, the on-the-spot mode of directly drawing schematic diagram of employing usually, adopts the instruments such as tape measure to carry out measurement by traffic police personnel on site and on-the-spot drafting road base map.The defect that the road base map that this mode is drawn exists is:
1, in road base map, the relativeness of atural object is inaccurate;
2, same section, the road base map disunity that different personnel draw, brings certain difficulty to the judgement of accident responsibility side;
3, the road base map of papery not easily preserve, file and information transmission and share;
4, by the restriction of on-the-spot drafting time, road base map randomness is comparatively large, contains uncomplete content;
For the problems referred to above, companies have studied many moneys traffic accident scene diagram drawing system both at home and abroad at present, as the Easy Street Draw system that Tianjin TECOM400 traffic accident scene diagram drawing system and A-T Solutions Easy company of the U.S. develop.These systems are focused on, from the drawing skill of solving road base map drawing practice, reducing the drafting time of road base map as far as possible, and the even embedded model of conventional intersections, in the hope of reducing the drafting problem of road base map.But because site road situation is complicated, be difficult to find directly corresponding road model, road base map still needs on-the-spot drafting.
Summary of the invention
Object of the present invention is exactly provide a kind of to be conducive to shortening that traffic accident treatment time, mapping precision are high, data contain the full road base map information processing method being applicable to rapid transit accident treatment to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
Be applicable to a road base map information processing method for rapid transit accident treatment, it is characterized in that, comprise the following steps:
1) gather basic path coordinate information by total powerstation, and send it to computing machine;
2) computing machine is according to road base map generation method formation base road base map symbolic information, and carries out connection drafting, generates road base map.
Described road base map generation method is specific as follows:
1) road base map symbolic information database is set up;
2) corresponding property value is set to each base map symbol in road base map symbolic information database, and store this attribute value information;
3) to each road base map symbol setting locator meams;
4) determine to exchange data to each road base map symbol, this exchange data packets draws together the coding of symbol, the locating information of symbol and uniquely determine all data of symbol.
Described road base map symbol comprises symbol 76, according to the drafting mode of symbol, be divided into: the large classification of A, B, C, D, E, F, G and H eight, wherein category-A contains symbol 39, category-B contains symbol 3, and C class contains symbol 11, and D class contains symbol 3, E class contains symbol 17, and F, G, H class comprises 1 symbol respectively; Specifically in table 2
