Tunnel traffic accidents investigation.
By communicating with maintenance departments of tunnel, and analyzing information about traffic accident, traffic accidents in tunnel show following rules: (1) Related with traffic capacity.
The influence of road surface sliding resistance is important for traffic safety, with decrease of concrete road surface sliding resistance, the accident occurring frequency increase quickly, the relationship between sliding resistance and traffic accident frequency is shown in Fig 7 Fig.7 Relationship between accident frequency and sideway force coefficient Using condition analysis on tunnel transition pavement structure.
Because cement concrete pavement has high strength, water resistant, long life, non-flammable characteristics and so on, it’s used popularly as tunnel pavement in domestic and international highway and urban road construction.

of the implementation of the transport industry environmental protection plan; 3, Transportation infrastructure and planning, integrated traffic transportation spread traffic humanistic philosophy, through the establishment of concepts ,understanding and implementation, Establish the new concept on “Security transportation , Green transportation , Humanities traffic " ; 4, Developed areas of traffic environmental protection inputs on increased support to less developed regions and support, effectively avoid traffic infrastructure construction and ecological environment protection of regional imbalances , and series problems; 5, Global coordination and harmonization of initiatives, international conventions and organizations pay attention to research in 21st century transportation construction and environmental protection in the new situation , solved the problems through coordination between national, regional issues of common concern and, concerted action with limited inputs to
For these problems , national and international pollution prevention organizations have been working for many years , has been the formation of a global set of effective prevention and emergency systems, including international conventions , national regulatory systems and management personnel , institutions and so on. 5.2 Urbanization, Comprehensive energy utilization and air pollution Circulation of air pollution and contaminants under the conditions peculiar migration behavior makes regional and global issues .
New integrated transport system of the original single waterway , highway, railway, aviation, long-distance pipeline for information technology portfolio , providing efficient, fast, specifications, safety logistics services , but also in vehicles, cohesion , information requirements, management, security put forward specific requirements.
Integrated transport system in the safety and security should be the environmental, safety , security aspects of actions, measures , efficient collaboration and unified organization for integrated transport system to provide the necessary high-speed operation safety basis and technical support .
