Embodiment
The road traffic accident analytical approach, its unusual part is: by Geographic Information System (GIS Geographic Information System),, with road data typing server, set up the geographic information database with map.Simultaneously,, by acquisition terminal, gather scene of a traffic accident data typing server, generate the traffic hazard point, set up the traffic hazard database.Afterwards, the traffic hazard database is imported geographic information database, demonstration scene of a traffic accident data, accident black-spot, escape accident are tracked down and arrest content on map, namely as shown in Figure 1.
With regard to the better embodiment of the present invention one, map subscript of the present invention is marked with place name information, and described map includes graphical map, the map of taking photo by plane.Like this, can be convenient to the accident point situation monitoring in later stage, also be convenient to command centre and call, and in conjunction with the information such as relevant enterprises and institutions, residential quarter and commercial location around the incident road, carry out crash analysis.
Further, for the ease of scene, deal with emergencies and dangerous situations, the place where the accident occurred point of employing includes guideboard numbering, road segments, lamp post serial number and coordinate.Be convenient to like this personnel of dealing with emergencies and dangerous situations and know the reporter position.For example: usually encounter in daily contact is alert, the litigant does not understand the road of garden, can't clearly explain the accurate location that accidents happened occurs, at this moment our person of receiving a crime report just can allow the litigant inform near the lamp post serial number that incident point is, and input system inquiry, system is this light pole of location rapidly, and the person of receiving a crime report just can be dispatched near the rapid responding of policeman accordingly, has reduced the time that a large amount of policemen delay because finding spot.
Simultaneously, according to the accident spot information zone occurred frequently of gathering that accidents happened, and the mode by spatial clustering, form accident black-spot and be mapped out.Like this, coordinate effectively investigation accident highway section occurred frequently of Geographic Information System.Show that through data the accident occur in crossing and the accident that occurs in highway section are quantitatively, almost equate on the order of severity.Before not enabling the present invention, analysis in the past usually is only limited to the crossing accident, does not refine to highway section and place accident.Simultaneously, rely on the existence by Geographic Information System, can adopt the mode of polymerization that scene of a traffic accident data are presented in system.Thus, can reach the engineer's scale according to map, adjacent accident be carried out polymerization show, let us is found out accident point occurred frequently easily, and in the process of further contraction scale, extent of polymerization can diminish, finally will carry out polymerization with the scope of 10M and show, as shown in Figure 2.And, accident black-spot can be gathered and carries out rank, the black section of formation accident is also carried out rank, both as shown in Figure 3.
Consider that can play certain escape accident tracks down and arrest, escape accident in the present invention is tracked down and arrest content, according to scene of a traffic accident data, estimate the speed of a motor vehicle according to road travel time or escape vehicle,, in conjunction with road data, calculate suspected vehicles within certain time period by space and estimate the position that arrives.Specifically, its interface can be as shown in Figure 4.
In conjunction with actual service condition of the present invention, scene of a traffic accident data comprise, place where the accident occurred point, accident time of origin, accident personal information, accident vehicle information, causes of incident, vehicle heading.Follow-up, can supplement on-the-spot audiovisual materials, the relevant law document of this accident.And, do not limit above content, can carry out at any time the expansion of related data.Reason is, traffic hazard is an event that space-time characterisation is very strong, different time, and the traffic hazard that different location occurs, the order of severity is different, and frequency is different, and car type is different, and crash type is also different., so binding time and spatial data go to analyze the data of traffic hazard, become inevitable.After software is combined, can carry out very easily the analysis of major accident, improve prevention, both as shown in Figure 5, can effectively show the road traffic accident of death toll 1-3 people.Simultaneously, can further generate Fig. 6 content, be presented at that the school doorway occurs because not guaranteeing the traffic hazard stain rank of hurting sb.'s feelings of motor vehicle that the safe opening car door causes and bicycle collision.We just can find from Fig. 6, and school's doorway machine motor-car on-board and off-board are breakneck behaviors, and crossing and greening step arrange unreasonable.
Like this, can incorporate all information of relevant road traffic accident wherein.For example: in specific region, Accident has occurred, click this accident icon, we just can see the scene photograph of this accident, and on-the-spot audiovisual materials even comprise the relevant law documents such as accident protocol, make us can omnibearing understanding traffic hazard.
And after being attached to method of the present invention in the road traffic accident analytic system, this system closely combines with the whole flow process of group's Traffic Accident Disposing, makes each accident people's police's routine work to complete in this system.Be in particular in: the accident file number is generated automatically by system, can not artificially change; After the case registration is complete, automatically distribute case to the accident treatment people's police by system, can not be selected by people's police oneself. system log (SYSLOG) each people's police's operational data, comprise workload, wind-up-case rate, the case of exceeding the time limit, drunk, without the case disposal number of the special cars such as the disposal number of the felony such as card and factory's hired car, bus, engineering truck, school bus, group has also formulated corresponding evaluation method for this reason, makes the especially careful and responsible often traffic hazard data of typing of each people's police.
The another one aspect, this system also provides a lot of facilities for people's police, and easy left-hand seat.In other words: this system is provided convenience for people's police search case, and system provides the accident inquiry mode of various conditions, and reflection rapidly; System provides the case warning function of exceeding the time limit, and prevents that people's police from violating dilatio legalis and settling a case; System provides much information typing port, and in the accident typing phase, the processing phase, the phase of winding up the case can be improved data for accident, has alleviated the working pressure of logging data for people's police.All these are all for obtaining complete, comprehensive, a real road traffic accident database.
The system that combines with the present invention hands over garden group of patrol police detachment to use in Suzhou City public security bureau at present, uses to contrast so far fatal accident in 2011 and fall rate on a year-on-year basis and reach 33.3%, and common accident rate of growth descends 43.6%.Main transformation point: the black section of modern main road impression city commercial center doorway accident, data analysis shows that between business term festivals or holidays, accident is occurred frequently.Measure: separately open the gateway, southern side, reduce modern main road traffic pressure, thus the reduction accident.Simultaneously, by loop intersection, east, main road, golden pheasant lake accident black-spot, data analysis shows that the traffic hazard that change lane causes accounts for 67%.Measure: thus forbid that overpass turns left to avoid to form low-angle with ground craspedodrome wagon flow and conflicts, thus the reduction accident.
