The invention discloses a method for predicting the expressway exit and time of an abnormal vehicle, and the method comprises the steps: collecting the data of a portal through which the abnormal vehicle passes in real time through an ETC portal monitoring system in the driving process of the abnormal vehicle, and uploading the data of the portal to a server; the server combines the historical traffic record data of the abnormal vehicle, and adopts a naive Bayes algorithm to perform real-time calculation and evaluation according to the historical traffic record data of the abnormal vehicle and the passing portal information, so as to complete the prediction of the exit of the abnormal vehicle and the time for reaching the predicted exit toll station; the server measures and calculates the speed between the first two gantries after automatically reading the speed, calculates the time as the speed from the current position to the destination, calculates and determines the exit toll station and the exit time in real time, and gradually improves the predicated determinacy of the exit toll station for the continuous increase of the amount of traffic information. And along with the reduction of the distance from the exit toll station, the precision of the predicted next time is gradually improved.

    本发明公开了一种预测异常车辆高速出口及时间的方法,异常车辆行驶过程中,ETC门架监测系统实时采集异常车辆经过的门架数据,并将门架数据上传至服务器;服务器结合异常车辆的历史通行记录数据,并根据异常车辆的历史通行记录数据和经过的门架信息采用朴素贝叶斯算法实时计算评估,以便于完成异常车辆的出口和到达预测出口收费站的时间的预测;服务器自动读取后对前两个门架之间的速度进行测算,同时作为当前位置到目的地的速度进行时间计算,实时计算并确定出口收费站以及出口时间,对于本次通行的信息量不断增加,逐步提高预测的出口收费站的确定性,并且随着距离出口收费站距离的缩小,预测的下道时间的精度也会逐渐提高。
