Discrimination of Traffic Lane Departure Based on GIS Using DGPS

As the function of a vehicle has been improved, safety has become one of the most important factors of a vehicle while driving, especially at high speed. Most traffic accidents are reported to be caused by driver carelessness and/or improper driving maneuvers whose resulting pattern is closely related with lane change. Especially, unpredictable circumstance due to irregular road conditions or poor visibility due to bad weather makes it impossible for drivers to keep lane and deteriorates driving safety. This paper proposes a method utilizing Differential Global Position System (DGPS) with Real-Time Kinematic (RTK) and pre-built Geographic Information System (GIS) to detect lane departure of a vehicle. The position of a vehicle measured by DGPS with RTK has 20 cm-level accuracy. The preconditioned GIS data giving accurate position information of the traffic lanes is used to set up coordinate system and to enable fast calculation of the relative position of the vehicle within the traffic lanes. This relative position can be used for safe driving by preventing the vehicle from departing lane carelessly. The proposed system can be a key component in functions such as vehicle guidance, driver alert and assistance, and the smart highway that eventually enables autonomous driving supporting system. Experimental results show the ability of the system to meet the accuracy and robustness to detect lane departure of a vehicle at high speed.
