Procedural Generation of Complex Roundabouts for Autonomous Vehicle Testing
This work addresses a gap in high-definition road generation for autonomous driving simulation, though it appears incremental as it focuses on a specific road segment.
The paper tackles the problem of generating realistic roundabouts for autonomous vehicle testing by introducing a procedural method that allows approaching roads to connect at any angle, producing non-circular lanes that resemble real-world roundabouts.
High-definition roads are an essential component of realistic driving scenario simulation for autonomous vehicle testing. Roundabouts are one of the key road segments that have not been thoroughly investigated. Based on the geometric constraints of the nearby road structure, this work presents a novel method for procedurally building roundabouts. The suggested method can result in roundabout lanes that are not perfectly circular and resemble real-world roundabouts by allowing approaching roadways to be connected to a roundabout at any angle. One can easily incorporate the roundabout in their HD road generation process or use the standalone roundabouts in scenario-based testing of autonomous driving.
