Abstract
The authors have proposed the lane keeping system using road-side markers and onboard laser sensor to achieve safer and smoother road traffic in adverse weather conditions. The system acquires the relative position of road-side passive markers by the laser sensor, and the absolute position of them by communication with road-side active markers. The system estimates a vehicle position in the lane from the both positional information of the markers and warns the driver of a lane departure risk to assist the driver to keep the lane. This paper explains the actual running test system to examine the system operation and performance.
