Abstract

In one embodiment, a routing request for routing an automated vehicle (ADV) from a source lane to a target lane is received. Determine one or more road paths from a source road to a target road. A road path includes zero or more intermediate roads between the source road and the target road, where each intermediate road includes one or more intermediate lanes. For each road path, one or more lane paths are determined. Each lane path includes a plurality of lanes combined to connect a source lane of the source road to a target lane of the target road via at least one intermediate lane of the intermediate road. Lane routing is used to plan a trajectory from the source lane of the source road to the target lane of the target road to drive the ADV according to the trajectory.

Description

technical field [0001] Embodiments of the present disclosure generally relate to operating autonomous vehicles. More specifically, embodiments of the present disclosure relate to route guidance systems for autonomous vehicles. Background technique [0002] Vehicles operating in an autonomous mode (e.g., driverless) can relieve occupants, especially the driver, from some driving-related duties. When operating in autonomous mode, the vehicle can navigate to various locations using on-board sensors, allowing the vehicle to drive with minimal human interaction or in some cases without any passengers. [0003] Routing similar to a global positioning system provides general level guidance indicating the general direction of the autonomous vehicle. Traditional route planning lacks efficiency and flexibility in searching for the best route. Contents of the invention [0004] One aspect of the present disclosure provides a computer-implemented method for operating an autonomous ...
