Lane information processing method and device, electronic equipment and storage medium

The invention provides a lane function division method, and relates to the technical field of intelligent traffic, in particular to lane function division. The method comprises the following steps: acquiring direction information, lane information and traffic flow information of the intersection; determining a constraint condition set of intersection lane function division based on a pre-constructed lane function division model; obtaining a lane function division result of the intersection based on the lane function division model and the constraint condition set by taking a preset objective function optimization as a target; wherein the lane function division result comprises the lane direction of any lane in any connection direction of the intersection. Whether the lane at the intersection is the entrance lane or not can serve as a control variable, and the entrance lane is judged in real time. Therefore, the entrance lane can be automatically solved and judged, the accuracy of judging the entrance lane is
