The Optimization Of Mountain Highway Traffic Signs And Deceleration Vibration Marking

In recent years, with the increase in China's highway mileage, road traffic accidents is rising, especially in the mountain roads, particularly in the performance. Traffic signs and deceleration vibration marking are important for the prevention of traffic accidents, it is also the main mountain road safety facilities. At present, the mountain road traffic signs and deceleration vibration marking- design and set up more confusion, it is necessary to optimize them to reduce the probability of the occurrence of traffic accidents.In this paper, the impact of mountain areas through the establishment of a risk factor for road safety set, an analysis of people, vehicles, road and traffic environment on the signs marking the settings and the impact of the design process, the main mountain road identified risk factors. On this basis, the study of mountain road signs and deceleration vibration marking of the optimization method. On this basis, the study of how the mountain road traffic signs and deceleration vibration marking to optimize. Research on the people, vehicles and road safety on the impact of roads in mountainous areas. Traffic signs in the area, put forward the principle of starting from the pilot visually, the layout of traffic signs and small, highly optimized text. Has been the subject of the country based on the dangerous section of mountain road accidents were optimize the content of signs. In sharp sections, in accordance with sections of vehicles turning in sharp features, it proposed a theoretical model of the speed limit and road design characteristics in line with the "non-standard" signs.Based on the distance, as the theory, analysis and to determine the risk of a section of mountain road (long and sharp downhill sections) traffic signs of the pre-set distance, as well as a different set spacing between signs. On a variety of signs and slow down the vibration in the mountains marking the location of dangerous road sections. Finally, examples of specific sections of the mountain highway traffic signs and slow down the vibration of the examples of marking to do the design and settings.
