改扩建中的石安高速公路通行能力研究

Research on the Shijiazhuang-Anyang Highway capacity in the reconstruction

对改扩建中边加宽施工边运营通车的石家庄-安阳高速公路,在实际调查的基础上,详细分析与计算了车辆的通行能力,即在特定时期,找出实际交通量与按实际路况计算的通行能力的关系,对石安高速交通量的减少进行了分析,并对现有路况的通行能力进行客观评价,为今后高速公路在加宽扩建中的通行能力研究提供基础参考资料。

For the Shijiazhuang -Anyang reconstruction highway opened to traffic in widening construction, on the basis of actual survey, detailed analysis and calculation of traffic capacity of the vehicle, namely in the specific period, find out the rela- tionship between the actual traffic volume and of road according to the actual road condition. Analyzed the capacity reduction of Shijiazhuang- Anyang Highway, and conduct objective evaluation on the existing road traffic capacity, provide the basis refer- ence for highway traffic capacity in widening expansion for the future study.
