The invention provides a road network risk early warning method, a road network risk early warning device and control equipment, which are used for early warning of front risks in a vehicle driving process. The road condition risk early warning method comprises the following steps: acquiring at least one risk area in a current road network, and determining a secondary risk area of each risk area; the secondary risk area refers to an area which contains the corresponding risk area and is spaced from the edge of the corresponding risk area by a preset distance; for each on-line vehicle entering the secondary risk area, combined with the actual driving track of each on-line vehicle and the distance between each on-line vehicle and the corresponding risk area, predicting the probability that each on-line vehicle passes through the risk area; and carrying out risk early warning on the online vehicles whose probabilities of passing through the risk area exceed a preset probability.

    本发明提供了一种路网风险预警方法、装置及控制设备,用于对车辆行驶过程中的前方风险预警。该路况风险预警方法,所述方法包括:获取当前路网中的至少一个风险区域,并确定各风险区域的次级风险区域;次级风险区域是指包含对应风险区域且与对应风险区域的边缘间隔预设距离的区域;对进入次级风险区域内的各在线车辆,结合各在线车辆的实际行驶轨迹以及各在线车辆与对应风险区域之间的距离,分别预测各在线车辆途经风险区域的概率;对途经风险区域的概率超过预设概率的在线车辆做风险预警。
