Abstract

The invention provides a method and device for planning a driving route. The method includes the steps of planning a driving route of a target vehicle from a starting position to a destination position by using a preset algorithm to obtain a planned route, wherein the planned route includes a plurality of road segments; querying the traffic service level of a target road segment to which the target vehicle enters in the case that the target vehicle runs according to the planned route; if the traffic service level of the target road segment is a preset level, adopting a decision tree pruning algorithm to calculate the driving route between the starting position and the destination position of the target road segment to obtain a local optimized route; replacing the target road segment by thelocal optimized route to update the planned route. In this way, when the target vehicle runs according to the planned route, the planned route can be updated according to the traffic service level ofthe target road segment to be entered, and the accuracy of the planned route is improved.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a planning method and device for a driving path. Background technique [0002] Hazardous chemicals, that is, hazardous chemicals, refer to highly toxic chemicals and other chemicals that are poisonous, corrosive, explosive, flammable, and combustion-supporting, and are harmful to the human body, facilities, and the environment. It can be seen that due to the dangerous nature of hazardous chemicals, various activities targeting hazardous chemicals must be properly carried out. For example, for the transportation of hazardous chemicals, with the development of the economy in recent years, the transportation of hazardous chemicals has become more and more frequent. Therefore, how to plan a suitable driving route for vehicles transporting hazardous chemicals to improve the transportation efficiency of hazardous chemicals , has become the top priority of hazardous chemical transport...
