高等级公路通车初期的合理交通量

The Reasonable Traffic Volume of the High-grade Highway During Early Stage of Opening of Traffic

本文分析了高等级公路的路段通行能力,提出了与之相适应的远景年限适应交通量;根据国道网交通量历年统计资料和国民经济发展建设长远期规划,预测高等级公路在设计年限内的交通量增长率范围;由定基法确定出高等级公路通车初期的合理交通量。

Based on the analysis of highway capacity,the Design Annual Average Daily Traffic(DAADT)value on high-grade highway,including freeway and stage-built freeway is recommended in the paper.The range of increment rate of traffic volume is forcasted by using annual statistic data of national trunk road network and national long-term economic development plan;finally,according to average increment rate equation,the reasonable traffic volume ranges in the early open-traffic period are determined.
