Research On Traffic Forecasting Methods Of Qi-Nen Part Of Jing-jia Road

The traffic is one of the fundamental basis of highway design and planning. Byscientific and rational prediction of traffic to determine its future development trends.According to the forecast results can determine the size and grade of the highway. Thetraffic forecasting is the key elements of highway design and planning. It has played acertain role in guiding practicality and the use of vision on the highway. According tothe traffic forecasts results, Optimizing the design of highway scale to avoid lossesand waste caused by design problems as much as possible. It will bring hugeeconomic and social benefits. Traffic analysis and forecasting is an important part ofthe preparatory work for the highway construction projects. How to predict andimprove the prediction accuracy are the key elements discussed in this article.In this paper, through investigation and analysis of traffic of the Qi-Nen part ofJing-Jia road, on the basis of the OD survey, observation and investigation of trafficand the traffic survey, analyzing traffic development level and characteristics of theline and its influencing area, providing basic data for the traffic forecast. Thencombining economic, social, technical investigation and analysis, using elasticcoefficient forecast method, giving the2020-year and2030-year scale and level ofdevelopment of the vision traffic of predict routes. It provides an important basis todetermine the technical level, engineering facilities standard and economic evaluationof the highway reconstruction works.
