| The theories and methods of road traffic volume forecast are systematicly and comprehensively stated.WanTang road in north-river district of ChongQingCity is taken as an example .Traffic Volume forecast methods has been employed in predicting the traffic volume of Wantang road . The theoretical results are important for technical rank,projection construction scale,econmic evaluationand the choices of investment.The main points are briefly summarised as follows: 1) The method of traffic volume forecast is researched.According to the relation between traffic statistic data and economic development,a new model of traffic economic development is established.Based on present O D data and the behaviors of traffic zone ,the future production and abstraction of traffic zone are forecasted. 2) Methods of traffic distribution including cause and transferring traffic distribution forecast are analyzed,the calculation flow chart and calculation properties are studied.A frator traffic distribution program is made by using Matlab. 3) The iteration process of short cut arithmetic is proposed.Genetic arithmetic is applied to equilibrium traffic distribution model.A good result is obtained. |
