Research on the technology for safe operation and management of alpine cold and high-altitude highway

This article describes and analyzes the road condition for a high altitude alpine road and the measures taken to ensure traffic safety and accessibility even in extreme weather conditions. It also in-depth analyzes the influence of various technical engineering management measures and their influence on the road safety. The article serves as a foundation for future design and management of roads in these kinds of extreme conditions. 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.
