Embodiment
Road traffic accident analytical approach, its unusual part is: by Geographic Information System (GISGeographicInformationSystem) by road data typing server, set up the geographic information database with map.Meanwhile, by acquisition terminal, gather scene of a traffic accident data inputting server, generate traffic hazard point, set up traffic hazard database.Afterwards, traffic hazard database is imported geographic information database, map shows scene of a traffic accident data, accident black-spot, escape accident track down and arrest content, namely as shown in Figure 1.
With regard to the present invention one preferably embodiment, map subscript of the present invention is marked with location name information, and described map includes graphical map, map of taking photo by plane.Like this, the accident point situation monitoring in later stage can be convenient to, also be convenient to command centre and call, and carry out crash analysis in conjunction with information such as enterprises and institutions relevant around incident road, community and commercial locations.
Further, deal with emergencies and dangerous situations for the ease of scene, the place where the accident occurred point of employing includes guideboard numbering, road segments, lamp post serial number and coordinate.Be convenient to the personnel of dealing with emergencies and dangerous situations like this and know reporter position.Such as: usually encounter in everyday exposure is alert, litigant does not understand the road of garden, clearly cannot state the accurate location that accidents happened occurs, at this moment our person of receiving a crime report just can allow litigant inform lamp post serial number near incident point, and input system inquiry, system can locate this light pole rapidly, and the person of receiving a crime report just can dispatch the rapid responding of neighbouring policeman accordingly, decreases the time that a large amount of policeman delays because finding spot.
Meanwhile, according to the accident spot information region that to gather that accidents happened occurred frequently, and by the mode of spatial clustering, form accident black-spot and be mapped out.Like this, coordinate Geographic Information System can section that effectively investigation accident is occurred frequently.The accident occurring in crossing through data display with occur in the accident in section quantitatively, the order of severity is almost equal.Before not enabling the present invention, analysis in the past is usually only limited to crossing accident, does not refine to section and place accident.Meanwhile, rely on the existence by Geographic Information System, the mode of polymerization can be adopted scene of a traffic accident data to be presented in systems in which.Thereby, it is possible to and according to the engineer's scale of map, adjacent accident is carried out polymerization and shows, let us finds out accident point occurred frequently easily, and in the process of further contraction scale, extent of polymerization can diminish, finally will carry out polymerization display with the scope of 10M, as shown in Figure 2.Further, accident black-spot can be carried out gathering and carry out rank, black section of formation accident also carries 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 tracks down and arrest content, according to scene of a traffic accident data, the speed of a motor vehicle is estimated 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 of arrival.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, traffic injury time, accident personal information, accident vehicle information, causes of incident, vehicle heading.Follow-up, the on-the-spot audiovisual materials of this accident, relevant law document can be supplemented.Further, do not limit above content, the expansion of related data can be carried out at any time.Reason is, traffic hazard is the event that a space-time characterisation is very strong, different time, the traffic hazard that different location occurs, and 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 the data analyzing traffic hazard, become inevitable.After being combined with software, the analysis of major accident can be carried out very easily, improve prevention, both as shown in Figure 5, effectively can show the road traffic accident of death toll 1-3 people.Meanwhile, Fig. 6 content can be generated further, be presented at that school doorway occurs because not guaranteeing the traffic accident black-spots rank of hurting sb.'s feelings that the motor vehicle that safe opening car door causes and bicycle bump against.From Fig. 6, we just can find, school's doorway machine motor-car on-board and off-board are breakneck behaviors, and crossing and greening step arrange unreasonable.
Like this, all information of related roads traffic hazard can be incorporated wherein.Such as: there occurs Accident in specific region, 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.
Further, after in methods combining of the present invention to road traffic accident analytic system, this system closely combines with the whole flow process of group's Traffic Accident Disposing, and the routine work of each accident people's police must be completed in such a system.Be in particular in: accident file number is generated automatically by system, can not artificially change; After case registration, automatically case is distributed to accident treatment people's police by system, can not to be selected by people's police oneself. the system log (SYSLOG) operational data of each people's police, comprise workload, wind-up-case rate, 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, the every Accident data of the typing making each people's police especially careful and responsible for this reason.
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, system provides the accident inquiry mode of various condition, and reflection rapidly; System provides case to exceed the time limit warning function, prevents people's police from violating dilatio legalis and settles a case; System provides much information typing port, and in the accident typing phase, the process phase, the phase of winding up the case can improve data for accident, for people's police alleviate the working pressure of logging data.All these are all for obtaining complete, comprehensive, a real road traffic accident database.
The system combined with the present invention hands over garden group of patrol police detachment to use in public security bureau of Suzhou City at present, and use contrast fatal accident in 2011 so far to fall rate on a year-on-year basis and reach 33.3%, common occurrences rate of growth declines 43.6%.Major alterations point: black section of modern main road impression city commercial center doorway accident, between data analysis display business term festivals or holidays, accident is occurred frequently.Measure: separately open gateway, southern side, reduces modern main road traffic pressure, thus reduction accident.Meanwhile, by loop intersection, east, main road, golden pheasant lake accident black-spot, the traffic hazard that data analysis display change lane causes accounts for 67%.Measure: forbid that overpass turns left thus avoids forming low-angle with ground craspedodrome wagon flow and conflict, thus reduction accident.
Can be found out by above-mentioned character express, adopt after the present invention, the combination between geographic information database, traffic hazard database can be passed through, map shows scene of a traffic accident data, accident black-spot, escape accident track down and arrest content.Thus, methods combining of the present invention is entered system, can by the existence of accident black-spot, the rule that analysis accident occurs, appearance of preventing accident.
