Sight Distance Detection Using LIDAR and GPS Data

Sight distance (SD) is important subject of traffic safety. Depending on SD driver is able to receive in time the necessary visual information about any obstacles on the road. Obstacle on road must be spotted in defined distance, so the driver could make a proper decision. The necessary stopping sight distances, which are based on extreme conditions of braking, can be considered during road design process. However, on roads that are already on use, the actual SD can differ from designed safe condition due to after built constructions, road facilities or vegetation, which can obstruct the necessary sight direction. A project on detecting of actual SD and other important sight parameters on existing roads is conducted in Riga Technical university Road and Bridge department. Proposed method allows detect and evaluate the actual SD parameters using together both - scanned 3D high-resolutio
