Safety is a key issue in railway operation. In this context, level crossings (LCs) are one of the most critical points in railway networks. In some countries, accidents at LC account for up to 50% of railway accidents. In this paper, we conduct a risk assessment comparative study involving two main types of Automatic Protection Systems (APSs), the first using a pair of half-barriers and the second...
China is striving to build "smooth, efficient, safe, green" transport system, which demand highway to meet traffic safety functional requirements and ensure the safety of roadside ecological environment as well. A lot of research in highway traffic safety at home and abroad have been carried out and achieved considerable results. However, there are few researches to combine the highway traffic...
Disastrous and traffic incidents have serious impact on the operation risk of major highway infrastructure, and risk calculation method is the basis for its safety management decision. Based on analysis of safety factors of major highway infrastructure, a combined method coupling fuzzy algorithm and Bayesian network is presented to calculate its operation risk under various events, in which fuzzy...
The characteristics of city underwater tunnels are unfavorable for evacuation. Reasonable design and evaluation of the evacuation capacity are the premise of the safety of tunnel users. An observation experiment was carried out by using the inner vertically evacuation with slide as research object. The velocity of getting off vehicle, the running speed and the evacuating capacity of the slide during...
Analyzing driving behavior decision risk is the key to evaluate the road traffic safety. In order to understand the production mechanism of behavior decision risk preferably, the application of information asymmetry theory will set up the decision risk of driving behavior model centering on the traffic accident probability, the accident severity and the traffic information asymmetry degree in this...
Foundation pit project is necessary for most projects. The accuracy of foundation pit is become more and more important accompanied by the rapid growth of super high-rise buildings and substructure works. The exterior-protected construction of foundation pit is temporary structures. But, the relatively low safety reserve of exterior-protected construction may lead to more risks. It is very difficult...
