Problems solved by technology

[0009] The main purpose of the present invention is to provide a new route planning and processing method by overcoming the defect that the existing simple turning restrictions cannot deal with complex control restrictions, or avoiding the inconvenience and burden of additionally constructing ghost arcs in the database in advance The method of prohibiting complex driving maneuvers, the technical problem to be solved is to dynamically generate a new type of restriction mask to avoid the prohibited complex driving maneuvers during the pathfinding process, while retaining the possibility of all traversable paths , very suitable for practical

Abstract

The invention relates to a method of route planning and handling prohibited complex driving maneuvers. An OPEN list and a CLOSED list of an A-Star algorithm are initiated. A first node from the OPEN list is selected as a processing node. One or multiple filtered complex maneuver restrictions of the first node are stored in a rule list before acquiring a second node connected to the processing node. The second node is added to the OPEN list when the second node is allowed to be selected according to the rule list.

Description

technical field [0001] The present invention relates to a method of route planning in the field of route planning, in particular to a method of route planning and processing prohibited complex driving manipulations. Background technique [0002] Today's navigation applications on mobile devices such as smartphones, desktop computers, or car navigation systems assist users in designing the best itinerary to a destination, help users know the direction of the vehicle and driving direction, explain various places of interest, and send Drivers are notified of driving conditions on the road network. [0003] As a vehicle moves along roads, streets, and highways, a vehicle may encounter two types of constraints in driving maneuverability: traffic constraints that are always present and vehicle constraints that vary by time of day, day of the week, or season. Examples of timed vehicle restrictions include no left-turn, no right-turn and no U-turn restrictions during commuting or r...
