对网络化条件下高速公路中服务设施布局问题进行了综合研究。首先分析了高速公路网络与孤立路段的本质差别在于枢纽节点的存在,进而对单独枢纽互通、枢纽互通相邻、线状排列、环状排列等各种情况,分别详细分析了相应路段的服务设施设置布局问题,总结了各种情况下服务设施合理布局的原则和方法。此后,针对服务设施布设间距的合理取值问题进行了专门研究,提出了服务的补给窗口理论,证明了服务设施布设间距与补给窗口之间的紧密联系,并对我国西部地区高速公路在极端情况下的服务设施布设问题进行了讨论。
A comprehensive study on the layout of service facilities in expressways under networked conditions was conducted. Firstly, the essential difference between the expressway network and the isolated section is analyzed in the following aspects: the existence of hub nodes, and the interconnection of individual hubs, the interconnection of hubs, the arrangement of linear and circular arrangements, and the detailed analysis of the service facilities Set the layout problem, summed up the principle and method of reasonable layout of service facilities in various situations. After that, the author made a special study on the reasonable value of the layout of service facilities, put forward the service supply window theory, proved the close connection between the service facilities and the supply window, Under the service facilities layout issues were discussed.
