Embodiment Construction

[0052] The technical solutions and beneficial effects of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0053] The present invention is an optimal path analysis method based on the weight of road corners. It mainly considers that the obstacle strength is constituted by the road section road resistance and the node road resistance. The road section road resistance, the node road resistance and the obstacle strength are all general terms in the technical field. Road resistance refers to the cost of vehicles passing through the road section, such as: time cost; node road resistance refers to the cost of vehicles passing through the node, such as: time cost; barrier strength refers to the amount of consumption that hinders vehicles from passing the road , Generally refers to the length of time. Link impedance value, that is, the time for a vehicle to complete its driving along a certain road section, is the main fact...

Abstract

The invention discloses an optimal path analyzing method based on road corner weight. The optimal path analyzing method comprises the following steps: step 1, a road network data model is built based on road layer data; step 2, a road corner weight auxiliary network is built based on the road network data model and auxiliary edges in the road corner weight auxiliary network are endowed with weight; step 3, a network dataset is generated based on the road corner weight auxiliary network and an objective function is set by considering path crossing steering total weight and path total length, the optimal path is obtained by adopting a shortest path analytic approach to analyze the network dataset; step 4, combined with the corner direction, the optimal path obtained in the step 3 is subjected to backstepping into the road network data model to obtain the authentic optimal path. Through the adoption of optimal path analyzing method based on road corner weight, operation lines can be effectively designed for the planning of urban public transportation lines and travelling, the cost and price brought by travelling through public transportation can be reduced greatly and the application propspect is wide.

Description

Technical field [0001] The invention belongs to the field of intelligent transportation technology, and in particular relates to an optimal path analysis method based on road corner weights. Background technique [0002] With the rapid economic development and the continuous improvement of people's living standards, urban transportation demand is growing rapidly. The increasing load of roads makes more and more people choose public transportation as their way of travel. However, due to the dense urban population, the large flow of motor vehicles, and the inadequate planning of urban roads, the advantages of the urban public transportation system have been difficult to maximize. The serious shortage of road capacity, the low level of traffic management technology, and poor service management have caused serious urban traffic problems, and traffic jams have become a common phenomenon. Designing a set of feasible operating routes for urban public transportation systems to solve tr...
