Study On The Traffic Forecast Of Beijing-taibei Expressway Project In Langfang

Project feasibility study is one of the early stage of project construction, but also to road construction, a powerful decision-making support system. Highway Engineering Project Feasibility Study contains a number of elements, of which traffic forecasts are one of the core of its research. It is a comprehensive analysis of the necessity and feasibility of construction projects, the foundation, but also to determine the technical grade highway construction projects, engineering, facility size, as well as the main basis for economic evaluation, traffic analysis and traffic forecast level of high and low, particularly in traffic forecasts the level and quality of the project will directly affect the decision-making more scientific. This north-Taiwan highway traffic volume is forecast to be Lang-fang Section title, the logical starting point in the relevant disciplines theory and settled on the practical application, has a high practical value and theoretical significance.Paper first introduces the research background item, select research methods, a clear thesis topics of significance; followed by proposed paragraph Northern Taiwan Expressway traffic forecasts Lang-fang ideas and the specific implementation steps; then right expressway project in Lang-fang traffic surveys and analysis, including the OD survey statistics, the regional characteristics of the distribution line of research, traffic statistics, major highways, rail traffic surveys; Finally, according to projections the basic steps for the North-sets a high volume of road traffic prediction, the main four stages according to Predicting traffic volume, including the occurrence of traffic volume, to attract cross-traffic and induced traffic volume, the methods used for the elasticity coefficient and economic growth, Everett law and stochastic user equilibrium method.
