Ego-Lane Index Estimation Based on Lane-Level Map and LiDAR Road Boundary Detection

Correct ego-lane index estimation is essential for lane change and decision making for intelligent vehicles, especially in global navigation satellite system (GNSS)-challenged environments. To achieve this, we propose an ego-lane index estimation approach in an urban scenario based on particle filte...
