Research on Multi Lane Coupling Traffic Volume Prediction Model Based on Improved Gravity Model—Taking a Road Project in Lianjiang County as an Example
In recent years,with the acceleration of urban development and the rapid growth of motor vehicle own-ership,the traffic problems in most cities have become increasingly prominent.Traffic volume prediction is partic-ularly important in the current process of traffiic planning.In the traditional traffic volume forecasting methods,the gravity model method is generally used for practice.However,the traditional gravity model has the disadvan-tages of delay and poor accuracy.Therefore,this paper puts forward the capacity analysis model based on different lane schemes,and discusses the different parameters of the model;at the same time,the gravity model and multi lane factors are coupled to form an improved gravity model.In practical application,taking a road project in Lian-jiang county as an example,the adaptive traffic volume under the dual lane management scheme is about 1012 pcu/h;the growth rate of local traffic volume in Lianjiang County will remain at about 9.87％from 2020 to 2035,so the model is feasible and effective.
