摘要
运营交通量预测是高速公路运营管理的重要工作之一。以往预测所需路段交通量和OD数据都是通过实地交通调查和OD反推得到,预测精度较低。预测时应充分考虑高速公路ETC的联网新背景,采用新的数据获取途径,提出增长率法和四阶段法相结合的高速公路运营交通量预测方法,并以岱黄高速为例对预测方法进行验证。
The forecasting of operational traffic volume is an important part of expressway operation and management.In the past,the required traffic volume and OD matrix are obtained through field traffic survey and OD Estimation,but the accuracy is relatively low.In order to give full consideration to the new background of expressway ETC networking while forecasting,a new method of data collection is used and a new method of expressway operational traffic volume which combines growth rate trend method with four-stage method is proposed,by taking Daihuang expressway as an example to demonstrate the proposed forecasting method.
