Research On The Safety Evaluation And Safety Management Technology In Highway Widen Project

Freeway with its high speed, high efficiency, safety, comfort features such as fully reflects the large flow, high speed advantage. Because the majority of Expressway in accordance with two-way four driveway construction standards, along with our country national economy fast development and the number of vehicles increases continuously, gradually exposed a series of road related security problems, quite a part of the early completion of the use of expressway has been unable to meet the increasing traffic volumes and the needs of social development, more and more highways need reconstructing. Therefore, expressway reconstruction and expansion of highway construction in our country is currently facing the field of important task..In order to improve the level of road traffic safety, establish and improve the highway traffic safety guarantee technology, measures and standards, the expansion of expressway project as the background, combined with the related research, the Freeway Rebuilding the safety index to carry on the research analysis, around the highway network safety, highway safety design and security, construction of traffic organization and traffic control and information service technology point of view, analysis of the expansion of expressway design and construction stages need to satisfy various security services characteristics and components of the system, and the eight Lane freeway operation stage of the safety index and safety management of research and analysis, put forward the related research results.Through the research, the implementation of reconstruction and expansion of highway safety design, safety protection and construction of area transportation organization, improve the entire highway information collecting and monitoring system, improve the line of traffic safety management and control system, improve the entire information service system, further integration of highway safety management and service system, constructing efficient and secure information service corridor, implementation freeway intelligent, integration management and services, thereby eliminating or reducing the accident hidden trouble, greatly reduce the freeway operating safety accidents and economic loss, improve traffic capacity for sustainable development, in order to achieve a good society, economic benefits.
