Abstract
This paper first explores reasons and risks of run-off-road crashes, then introduces a lane departure warning system (LDWS) in the hope of reducing frequency of such crashes substantially. Deviations were divided into three levels. In this research, Badaling Freeway was selected as the study roadway section. According to historical safety records, traffic crashes occurred frequently on this freeway heading to Beijing direction, which was located in mountain areas. Paper picked out segments between 51.5 km and 55.6km to collect pertinent information of drivers' lane departures by digit video for a week. Lane departures data were detracted by digit video from 10:00 am to 16:00 pm for one week. Observed departure values were divided into several groups and aggregated into four categories to orient different levels of vehicles leaving behaviors. Result lays a solid foundation for further development of lane departure warning system (LDWS) for mountainous freeways in China.
