Probe into road traffic safety modeassessment

This paper aims to propose a new evaluation index known as road recognized safety index to improve the road traffic safety evaluation. The common characteristic of traffic accidents is the black-spots of the domestic express highways where the practical driving speeds for most drivers are much faster than they are allowed. Besides, from the point of view of desirable control of the relation between the driver, the vehicle and the road, the environment system safety, the road design safety and the generally acceptable safety rules are to be defined primarily. Starting from this basis, we also analyze the qualitative relation between the index of road cognized safety and the actual safety level of the road, which indicates the significance of the road cognized safety evaluation mode in carrying out new humanistic road design theory and in scientifically analyzable traffic accidents' causes on the road black-spots. Finally, a pilot plan of road cognized safety evaluation is also put forward.
