Research on Traffic Accident and Braking Safe Performances of Interurban Coach
In order to define the situation of traffic safety about highway passenger transport accurately, and reveal the statistical regularity of braking safe performances on interurban coaches, the traffic accident data of Chinese highway passenger transport in recent years were analyzed. The results show that the traffic injury caused by the hidden dangers of vehicle braking system was becoming more serious day by day, the mortality per 10 thousand vehicle of highway passenger,transport was up to 26.828 person/104 vehicle, and the mortality per 100 million vehicle kilometer was up to 6.555 person/10s kilometer-vehicle. Based on a large sample braking performances detection of a given type interurban coach, the statistical models about 4 braking performances were established. This research shows that the unqualified rate of front axle braking force balance performance oftbe given type interurban coach goes beyond 24％, and the rear one is 7％ as well, which could be one serious hidden danger. The models established have very high calculating precision. What makes this conclusion more persuasive is the relative error maximum between model calculating values and real detecting results is 0.428％ only. In addition, the practicable direction and ways to solve the exposed problems in vehicle braking system are given. The research results can be used to understand the present condition of highway passenger transport in China and the braking perfonnances statistical regularity of typical interurban coach accurately, providing a reliable technical guarantee for improving traffic safety.
