[0019] 若当前车速大于安全车速阈值 V0 (即 V〉V0) ， 则生成危险指数 X， 并预警。 [0019] If the current vehicle speed is greater than the safe vehicle speed threshold V0 (ie, V>V0), a risk index X is generated and an early warning is issued.
[0020] 具体实施吋， 需要生成高危路段网格列表； 其中网格列表是把地图平均划分出 的网格， 比如把福州划分成 10000*15000个网格， 网格内包含有路段， 所以可根 据这些路段网格选出发生事故较多的路段网格， 列表中可以包括网格编号以及 对应的路段编号、 路段等级、 事故发生量、 路段限速及路段长度等信息。 具体 为： [0020] In the specific implementation, a high-risk road segment grid list needs to be generated; wherein the grid list is a grid that divides the map into an average, for example, dividing Fuzhou into 10000*15000 grids, and the grid includes road segments, so According to the grid of these road sections, the grid of the road segment with more accidents is selected. The list may include the grid number and the corresponding road segment number, link grade, accident occurrence amount, link speed limit and link length. Specifically:
[0021] 获取特定区段的地图数据； [0021] acquiring map data of a specific section;
[0022] 选取地图中限定不同车速的路段区域； 如地图中的快速路、 高速路、 国道、 省 道等车辆速度较快的道路区域； [0022] selecting a road segment area in the map that defines different vehicle speeds; for example, a fast road, a highway, a national highway, a provincial highway, and the like, where the vehicle speed is faster;
[0023] 网格化所述区域， 并编号；
[0024] 读取第一特定吋间段， 例如最近一年内的事故处理记录信息， 并与网格化的区 域匹配， 更新事故处理记录信息， 获取事故发生量， 并保存； 其中事故发生量 S =S'+L， S'为实际事故发生量， L为事故严重等级， L取值范围例如为 0-10， 例如 实际事故发生量为 20， 其中两件事故严重等级为 5， 三件为 3， 其余均为 0， 则该 路段的事故发生量 S为 20+5*2+3*3=39。 [0023] meshing the regions, and numbering; [0024] reading the first specific inter-segment, for example, the accident processing record information in the last year, and matching with the gridded area, updating the accident processing record information, obtaining the accident occurrence amount, and saving; wherein the accident occurrence amount S =S'+L, S' is the actual accident occurrence, L is the accident severity level, L is for example 0-10, for example, the actual accident occurrence is 20, and the two accident severity levels are 5, three 3, the rest are 0, then the accident occurrence S of the road section is 20+5*2+3*3=39.
[0025] 依次判断各个路段区域事故发生量 S是否大于事故发生量阈值 SO; [0025] sequentially determining whether the accident occurrence amount S in each road section is greater than the accident occurrence threshold S;
[0026] 对所有网格路段按上述方式统计事故发生量， 将事故发生量大于事故发生量阈 值的路段区域加入高危路段事故处理记录列表， 并存储； 其中， 高危路段事故 处理记录列表可从交警部门或者保险公司中获取事故处理清单， 其保存有原始 数据， 并在这些记录清单来计算出同等情况下的事故发生量。 [0026] The accident occurrence amount is calculated for all the mesh road sections in the above manner, and the road section area where the accident occurrence amount is larger than the accident occurrence amount threshold value is added to the high-risk road section accident processing record list, and stored; wherein, the high-risk road section accident processing record list can be obtained from the traffic police The department or insurance company obtains an accident handling list, which holds the original data, and calculates the amount of accidents under the same circumstances in these records.
[0027] 然后读取每个网格路段近期的第二特定吋间段， 例如最近三个月内 （如 [tl， t2] ) 的事故处理记录信息， 根据上述事故处理记录信息获取第二吋间段内的事故 发生量 Sl， 修改相应网格路段的数据发生量， 并更新事故处理记录信息， 具体 的， 若在该第二特定吋间段内该路段事故发生量减少了， 说明该路段可能已经 过改造， 或已设置一些提醒功能等， 则事故发生量 S可相应减去减少值 Sn0， 所 述减少值 SnO取值范围例如 5-10， 具体可根据第二特定吋间段的事故发生量的减 少量来确定， 减少量越大， 则 SnO取值越大。 若在该第二特定吋间段内仍然没有 减少， 则更新该路段的事故发生量 S为 Sl。 [0027] then reading the second specific inter-section of each grid segment, such as the accident processing record information in the last three months (such as [tl, t2]), and obtaining the second defect according to the above-mentioned accident processing record information. The accident occurrence amount S1 in the interval, modifying the data occurrence amount of the corresponding grid section, and updating the accident processing record information. Specifically, if the accident amount of the road section is reduced in the second specific section, the section is indicated If the modification has been made, or some reminder function has been set, the accident occurrence amount S may be correspondingly reduced by the reduction value Sn0, and the reduction value SnO may be in the range of 5-10, for example, according to the second specific interval. The amount of reduction in the amount of occurrence is determined, and the larger the amount of reduction, the larger the value of SnO. If there is still no decrease in the second specific interval, the incident occurrence amount S of the updated section is Sl.
[0028] 对每个网格路段都进行上述的是否存在减少值的判断后， 将更新后的事故发生 量进行记录， 并存储至高危路段网格列表； [0028] After performing the above determination of whether there is a decrease value for each of the mesh segments, the updated accident occurrence amount is recorded and stored in the high-risk road segment grid list;
[0029] 按照事故发生量对所有网格进行排序， 并对每个高危路段设置相应的车速阈值 vo， 将该阈值与网格路段关联保存至高危路段网格列表。 优选的， 所述高危路 段网格列表还包括事故发生的吋间、 天气等信息。 [0029] All the grids are sorted according to the accident occurrence amount, and a corresponding vehicle speed threshold vo is set for each high-risk road section, and the threshold value is associated with the grid road section and saved to the high-risk road segment grid list. Preferably, the high-risk road grid list further includes information such as the daytime, weather, and the like of the accident.
[0030] 当车辆行驶在相关道路上吋， 可通过车载网络模块或车内人员携带的手机等移 动终端的应用程序获取车辆当前位置以及高危路段网格列表， 所述高危路段网 格列表可从车管局等监控中心的数据库中获取。 所述网络模块或应用程序判断 车辆运行前方是否有高危路段， 例如判断前方 2公里内是否有高危路段， 若有， 则判断当前车速 V是否达到相关路段的车速阈值 V0， 若达到则发出警报提醒驾驶
员减速。 [0030] When the vehicle is traveling on the relevant road, the current location of the vehicle and the high-risk road segment grid list may be obtained by an application program of the mobile terminal such as a mobile phone module or a mobile phone carried by the in-vehicle personnel, and the high-risk road segment grid list may be Obtained in the database of the monitoring center such as the Vehicle Administration. The network module or application determines whether there is a high-risk road section in front of the vehicle running, for example, determining whether there is a high-risk road section within 2 km ahead, and if so, determining whether the current vehicle speed V reaches the vehicle speed threshold value V0 of the relevant road section, and if so, issuing an alarm reminder Driving The staff slowed down.
[0031] 优选的， 在判断前方存在高危路段后， 所述网络模块或应用程序进一步获取当 前吋间及当前天气信息； [0031] Preferably, after determining that there is a high-risk road ahead, the network module or application further obtains current current and current weather information;
[0032] 在高危路段网格列表中査找与当前吋间及当前天气信息相同的吋间段记录数 N[0032] Find the number of inter-segment records in the high-risk road grid list that are the same as the current day and current weather information.
Time与天气状况记录数 NTmp， 并综合分析生成生成危险指数 X， 其中 X=ot*SgO+ β* V/V0+Y*NTime+5*NTmp； 其中， SgO对应 grid网格内事故发生量， α、 β、 γ、 δ为加权系数。 Time and weather record number NTmp, and comprehensive analysis generates a generated hazard index X, where X=ot*SgO+ β* V/V0+Y*NTime+5*NTmp; where SgO corresponds to the amount of accidents in the grid grid, α , β, γ, δ are weighting coefficients.
[0033] 根据危险指数发出预警。 [0033] An early warning is issued based on the risk index.
[0034] 若车辆行驶前方不存在高危网格或当前车速小于等于安全车速阈值， 则返回步 骤"读取车辆当前位置信息以及高危路段网格列表"。 [0034] If there is no high-risk grid ahead of the vehicle or the current vehicle speed is less than or equal to the safe vehicle speed threshold, then return to the step of "reading the vehicle current position information and the high-risk road segment grid list".
[0035] 在实际应用中， 本发明在统计出一些高危路段后， 当司机靠近危险路段吋， 并 且车速较快的吋候， 可由车载终端获取当前吋间和天气， 然后由事故发生数据 库中匹配出同样天气车速吋间段的事故发生情况， 由此得出危险路段驾驶危险 指数 X， 根据 X的大小对司机进行预警。 [0035] In practical applications, after counting some high-risk road sections, when the driver approaches the dangerous road section and the vehicle speed is fast, the current time and weather can be obtained by the vehicle-mounted terminal, and then matched by the accident occurrence database. The accident occurred in the same weather at the speed of the vehicle, and the danger index X of the dangerous section was obtained, and the driver was alerted according to the size of X.
[0036] 区别于现有技术， 本发明通过在车辆行驶到高危网格附近吋， 获取车辆当前车 速， 并判断是否大于安全车速阈值， 若是， 则生成对应的危险指数， 并对司机 预警。 通过上述方式， 本发明可以高危路段的发现、 更新及预警， 提前在司机 靠近高危路段吋提醒司机， 使司机能够更加集中精力， 放慢车速， 从而减少交 通事故的发生。 [0036] Different from the prior art, the present invention obtains the current vehicle speed by driving the vehicle to the vicinity of the high-risk grid, and determines whether it is greater than the safe vehicle speed threshold. If yes, a corresponding risk index is generated, and the driver is alerted. Through the above manner, the invention can detect, update and early warning of high-risk road sections, remind the driver in advance when the driver approaches the high-risk road section, so that the driver can concentrate more and slow down the speed, thereby reducing the occurrence of traffic accidents.
