目前 ,四阶段交通需求预测模型得到了广泛的应用。后涌式交通需求预测是以四阶段模型为基础的改进方法 ,它克服了传统的四阶段模型无法考虑交通供给对交通需求影响的缺陷 ,通过研究交通供给设施对交通需求的影响机理 ,在四阶段模型中引入了反映路网、路线、路段的服务水平参数 ,使得整个模型系统能够充分反映交通供给与交通需求的互动作用。 At present, four-stage traffic demand forecasting model has been widely used. After-rush traffic demand forecasting is an improved method based on four-stage model, which overcomes the defect that the traditional four-stage model can not consider the impact of traffic supply on traffic demand. By studying the impact mechanism of traffic supply facilities on traffic demand, The service level parameters reflecting the road network, route and road sections are introduced into the stage model so that the entire model system can fully reflect the interaction between traffic supply and traffic demand.
