Embodiment Construction
[0034] In the prior art, the road restricts the size and weight of the vehicle. Users can only obtain the restriction information through the road signs when they are about to enter the road section, which causes the driver of the vehicle to make a U-turn and detour, which increases the occurrence of traffic violations. or the risk of an accident. If overweight vehicles forcefully pass through this section of road regardless of the weight limit in the road, it will easily cause destructive damage to the road and reduce its operating life. If super-high or super-wide vehicles ignore the height and width restrictions in the road and forcefully pass through this section of road, it will easily cause road congestion and affect the normal operation of the entire road.
[0035] To this end, the present invention provides a route planning method and system. In the process of route planning, after obtaining the route preference information, starting point and destination of the vehicl...

The invention discloses a path planning method and system. The path planning method comprises the steps of obtaining path optimization information, a launching point and a destination of a vehicle, and planning a reference navigation path of the vehicle, wherein the reference navigation path comprises a name and corresponding traffic control information of a road segment; obtaining vehicle information of the vehicle, and judging whether the reference navigation path contains a traffic control road segment with road segment traffic control information with which the vehicle information of the vehicle is not matched; if yes, replanning a reference navigation path of the traffic control road segment, and replacing the corresponding road segment navigation path in the reference navigation path with the replanned navigation path of the traffic control road segment to form an actual navigation path. According to the path planning method, the phenomenon that the vehicle takes a detour due to the fact that the size or weight of the vehicle is limited by a road can be avoided, the probability of traffic jams and accidents can be lowered, and meanwhile the problems that a road is bumpy and the service life of the road is short due to the fact that overweight vehicles pass through the road can be solved.
Description
technical field [0001] The invention relates to the field of traffic technology, in particular to a path planning method and system. Background technique [0002] With the development of the automobile industry and the road business, the number of motor vehicles is increasing day by day, and the density of the road network is constantly increasing to meet the operating efficiency of vehicles on the road and improve the smoothness of road traffic. [0003] In order to further improve the traffic efficiency of the road, the vehicles passing through different road sections are restricted. Taking the inner ring of Shanghai as an example, the inner ring road only allows vehicles of limited size (height, width) or limited weight to pass through, so as to ensure the operating efficiency of vehicles in the urban area of Shanghai, the safety of vehicles, and the service life of the road. [0004] However, when a vehicle passes through an unfamiliar road, the driver cannot know in ...
