The method for guiding the vehicle to turn at the congested intersection is suitable for the condition that the lane to be turned is a bidirectional lane, data transmission is carried out through means of internet of vehicles, big data and the like, and the method is not suitable for old vehicles or vehicles without navigation systems, so that the vehicles which are not suitable for the method are regarded as forward running vehicles and are not counted in the vehicle to be turned.
Preferably, when a straight-going vehicle exists between adjacent vehicle groups, a second guide path is generated for the vehicle group arranged behind the straight-going vehicle, so that the passing efficiency is improved, the queuing time is reduced, and the influence of the straight-going vehicle on a steering vehicle is avoided.
Preferably, the acquiring the congestion distance of the first lane D1 at the intersection includes: the method comprises the steps that the jam distance is obtained through acquisition equipment arranged on a road and a crossing, the jam distance is transmitted to a data center, data of the data center are transmitted to a vehicle through a vehicle-mounted navigation system, and a route guide path is generated.
