The mode cannot adapt to the traffic demand changing in real time, so that the resource allocation of steering lanes at intersections is stiff, the space utilization rate of the tidal traffic phenomenon road section is low, and the like. To alleviate this problem, the prior art proposes some improvements. The first type is a variable guide lane, and the driving direction of a single lane is changed by arranging a sign above an intersection. However, such techniques can only change the logical function of the lanes, cannot change the physical layout and number of lanes, have limited optimality, and are prone to driver confusion. The second category of technology involves "virtual lane lines" which sense the environment through on-board sensors or roadside devices and generate virtual lane line guidance for the driver on an on-board display screen or augmented reality head up display. The technology is essentially an information enhancement means, does not change road infrastructure in the physical world substantially, cannot form effective constraint on non-networked vehicles, and has limited effect in mixed traffic scenes.
