Study On The Safety Model And Its Usage Based On The Vehicle-road Coupling In Mountain Road

Dynamic vehicle-road interaction is a new scientific branch. It deals with these main parts:vehicle, road, and dynamic problem of their interaction. Of the three parts, the study on the last one is still weak. The environment of the mountain road is special because of the dangerous line which the blind bend, long declivity and line with the blind bend and long declivity is more dangerous. The design of the route is only under the power to upgrade but ignoring the interaction of the vehicle and the road. To fetch up the bug of the research of the interaction of the vehicle and the road, the article brings forward a new safety model which is based on the vehicle-road coupling model. In the new model, the actor brings up the effect of the interaction of the vehicle and the road to the safety running in mountain road. To constitute the new model, the article makes some research to the vehicle-road coupling and the running condition of the mountain road, the research contains the follow factors:1. the accident character happened in the mountain road especially in the blind bend and the long declivity line.The mountain roads have their only characteristic. The article names the blind bend, long declivity as the special line, and the model which is constituted is aimed at these special lines. To constitute the model, the guidelines are obligatory, the choose of these guidelines, we should consider the traffic accident happened in these special lines, analyse the state of the vehicle and the road when the accident happening and at last, we should analyse the influence to the special mountain road when these status happens.2. the research of the mechanism to the vehicle-road couplingThe analysis to the bearing capacity which is caused by the vehicle and road is very important. The unknit line supply a hurry, safety and comfortable running condition, and which also can lessen the attaint to the road in older to advance the using performance of the road and extend the using age of the road. The vehicle and the road is an interaction system, to improve the safety of the road, we should study the system as integer. In the vehicle-road coupling, the portrait drag index, the speed and the landscape orientation index are effect the safety of the running vehicle, so when we constitute the model, we should considered these indexes, and based on these indexes to constitute the model. 3. the usage of the safety modelAfter the constitution of the safety model, we could make use it as the reference to the design to the mountain road and the advance alarm to the safety of the mountain road...
