The invention discloses a vehicle high-risk road section early warning method. The method comprises the steps: preprocessing acquired vehicle basic data to obtain preprocessed basic data; on the basisof the preprocessed basic data, constructing a high-risk road section early warning model, and setting the rule for constructing the high-risk road section early warning model is as follows: when a distance between the vehicle and a danger marker is smaller than or equal to a preset distance, the vehicle is determined to be within the preset range of the danger marker, and early warning information is sent to a user; a high-risk road section early warning model is operated through vehicle track point data in the preprocessed basic data to obtain historical road section information network data, and the historical road section information network data are stored in a database; and a vehicle terminal acquires and outputs a query result corresponding to query information based on the historical road section information network data and the received query information. With the method, the accuracy and timeliness of early warning of the high-risk road section can be improved, and the dataof each region can be shared in real time.

    本发明公开了一种车辆高危路段预警方法,包括:对获取到的车辆基础数据进行预处理,得到预处理后的基础数据;基于预处理后的基础数据,构建高危路段预警模型,构建高危路段预警模型的规则为:当车辆与危险标志物的距离小于等于预设距离时,确定车辆在危险标志物的预设范围内,并向用户发出预警信息;通过预处理后的基础数据中的车辆轨迹点数据运行高危路段预警模型,得到历史路段信息网数据,并将历史路段信息网数据保存在数据库中;车辆终端基于历史路段信息网数据以及接收到的查询信息,获取并输出与查询信息对应的查询结果。通过上述方法,可以提高高危路段预警的准确率以及时效性,而且各个区域的数据可以实时共享。
