- objective to build up a systematic mountain road safety enhancement technology, this study analyses severe traffic crashes from 2006 to 2010 occurred on an inter-regional mountain arterial road network in south China. In order to digest these crash data collected from local traffic police stations, the authors conduct the in-depth crash analysis from the aspect of human, vehicle, road, and management. By developing the definition sets for crash deterministic causing factors judging system, the deterministic causes of severe accidents on mountain roads in China are deeply investigated. Results of our analysis indicate that human factor does weigh the most in the occurrence of the severe crashes; main crash types on mountain roads are running-off road, headon collision, overturned; Almost 76% severe crashes occurred on slope/curve combination sites; and freight car shall be given more attentions in reducing the severe accidents.

- The optical illusion deceleration marking is one of the commonly used speed control measures. In this research, the authors analyzed operating speed and trajectory of motor vehicle at intersection where optical illusion deceleration marking is installed. Quantitative and qualitative evaluation on effect of optical illusion deceleration marking is conducted. Results showed that optical illusion deceleration marking would help to reduce operating speed and average speed by 5-10km/h, to regulate motorcycle driver behavior, and to reduce speed difference, so that driving safety is ensured. Optical illusion deceleration marking is suitable for accident prone road sections on two-lane highways which main vehicle types are passenger car and motorcycle.

Effects of Roadway Segment Alignments and Locations on Rural Two-Lane Highway Crash Rates

- This paper investigates the effects of road segment alignment and location on rural two-lane highway crash rates by taking the mileage of segment types into consideration. Roadway segments are classified and redefined according to the segment alignment and location. The definitions of crash rates in terms of segment alignment and location are presented respectively. The study gathers crash data and the roadway geometric information of rural two-lane highways in southwest of China and crash rates of each segment type are proposed by utilizing the proposed definitions. The result indicates that gentle-slope & sharp-curve segments and intersections tend to have extremely higher crash rates than the other types of segments.
