Security Technology Research Of Mountainous Rural Passenger Transportation Based On The Car-Road Coupling Mechanism

Rural highway connects the county, township and administrative villages. It is the fundamental, pioneering and service facilities to solve the "three rural problems". The sixteenth National People’s Congress representative assembly and ministries put forward the slogan of "New Countryside Construction" and "Fixed Rural Road". Besides, the central government invests nearly 80 billion RMB into rural highway instruction in 2014. These measures promote rural roads into rapid development phase.In mountainous rural areas, the terrain is complex and rugged. And the economic foundation is poor. Although the department raises the fund subsidies standards, there is a big funding gap on highway construction. The situation of the poor road conditions have not been fundamentally changed. Road built along the mountain valleys, curve and long ramp. High embankment, road alignment and pavement subgrade quality and roadside protective facilities cannot been improve in a timely manner. Highway maintenance is insufficient.In terms of passenger vehicles, a large part of them is second-hand or illegal operating. In Peng Shui, the illegal operating vehicles occupy 70% of the market. And some of them is not suitable for mountainous rural highway linear condition. Mountainous rural road passenger transportation is likely to cause a major road traffic accidents and causes cause large death, injury and huge economic loss. Therefore, the relevant departments should pay more attention to mountainous rural road passenger transportation.This paper includes the following sections:first,it expounds the features of the mountainous rural highway passenger transportation accident characteristics and affected factors from investigation and analysis;second,it treats the mountainous rural highway passenger vehicle and road conditions as a whole of mutual coupling target to analyse the car-road coupling mechanism. Based on these study results,the paper finally puts forward the security assessment technology, security technology and relevant security policy to ensure the safety of the passenger vehicle operations.Mountainous rural highway passenger security assessment technology mainly includes the downhill and the bend sections assessment technology. It acts by comparing the maximum speed threshold and actual speed value to monitoring purposes. Mountainous rural highway passenger security technology mainly includes the passenger vehicle traffic conditions and security facilities set technology on the typical road. The purpose of passenger vehicle traffic conditions is to control vehicle access from the source and ensure the security of mountainous rural highway passenger transport. Security facilities set technology mainly take typical mountainous rural highway sections into consideration to ensure the mountainous rural highway passenger security in the operation.
