Study On Model Of Regional Freeway Reconstruction And Traffic Assign Technology

Traffic network is the framework of regional geographical space and the bond ofsocio-economic activities. Its formation and development depend on the region evolution ofspace structure and socio-economic development levels, in turn, traffic guides and promotesthe structure of regional space for further adjustment and new development of socio-economic.Traffic network, particularly the developed freeway decides the breadth and depth ofinteraction between regional geo-spatial, reflects the development and civilization level of theregional political, economic and society, and it is also an important symbol of the country'smodernization. The development of transport network has undergone a process fromquantitative change to qualitative change; freeway reconstruction is the direct manifestationfor the development law.Scientific and reasonable model of the freeway reconstruction and standarddecision-making is the basis for traffic sustainable development. This Paper discussedregional development strategic objectives and the transport supply and demand balancemechanism, from the regional space evolution and the theory of economic development. Thepaper forecasted the development trend of traffic demand, using quantitative analysis, whichprovided a reliable theory for the planning, construction of regional transportation system;This dissertation revealed the dynamic development of relations among traffic, regionalsocio-economic, resources and environment, and based on optimized allocation of landresources, established one mathematical model to calculate the reasonable size of regionaltransport land using macroeconomic theory and grey planning theory. Combining the overallregional integration Planning, the paper discussed freeway reconstruction mode; Based on thetraffic flow theory, it analyzed traffic operation mechanism and design concept of freeway,discussed on the relationship between freeway lane, speed, and the service traffic volume,proposed design ideas and construction standards of freeway reconstruction project.One close traffic organization program and management system is key to freewayreconstruction. This paper constructed mathematical model to assign traffic flow at differentlevels and sub-regional of regional traffic network framework, which based on the analysis ofregional traffic network framework and traffic planning theory. The previous work laid atheoretical foundation for establishing one expedite traffic assign program. On base of trafficinvestigation and traffic distribution of network, combining specific circumstances of freewayreconstruction, the paper laid one pertinence traffic organizing project flexibly andspecifically, then adopted a reasonable index system and scientific method to evaluate andadjust the project; This paper also analyzed affecting traffic safety and straightway factors,influence range, behavior mechanism and influence degree during freeway reconstruction,using system theory methods, At last dissertation improved on traffic running environmentand condition, putted forward traffic management system, using engineering, economic andtraffic management measures, which brined forward an essential system guarantee forregional traffic safety and smooth.
