Study On Side Highway Safety Technology And Application

Safety is a concern for social issues, road transport is an eternal theme. By improving road design to improve safety conditions are extremely important. Roadside of the current security protection designed to enhance road safety has become indispensable to the performance of an important part.According to China's roadside safety of the status and characteristics of the road side proportion of the number of accidents, weather conditions, models, the accident form, injured in the crash, the direction of the exit, road alignment, and other various angles, the low grade of the road two-lane highways Side accident of a macro statistical analysis, try to find out what impact the safety and security of road side factors. Combining engineering practice, the establishment of the theory based on the grey cluster 4 (Class I, Class II, Class III and Class IV, said the higher-level road safety side, the lower level) the lateral danger rating assessment, and proceeded to put forward a different risk levels should be set up under the protective type facilities.Roadside on the design and definition of the concept of tolerance specific application - "Roadside clear zone", pointing out the way to achieve tolerance measured the specific design steps. On this basis, according to vehicle out of the occurrence of road accidents, the following priorities for a systematic roadside safety protection technology for tolerance design concept: technology to prevent vehicles from leaving the road out of the lane, a vehicle collision and rollover accident protection technology, technology to reduce out of a collision between vehicles and road accidents seriousness.Finally, the side of the highway typical investigation into security issues, from the side of road safety tolerance design concept and reasonable way the side net perspective, roadside ditch design was not standardized, less than shoulder width, not a divider special End dealt with the transition unreasonable barrier, the lack of warning corners, targeted to technical protection measures.and give a summary of the article and Prospect.
