| 摘 要： | 针对公路重大交通基础设施(如特大桥、长大隧道等)的分布特征,从交通安全管理的角度,提出哑铃型路网的概念,重点对其路网边界算法进行探讨.在分析边界类型及约束特征基础上,构建时间成本效益函数作为目标函数,根据不同的交通流量,推导出哑铃型路网的边界算法.边界算法的实现是哑铃型路网整体算法的基础.为后期通路求解、路线诱行以及路网安全管理研究提供了分析平台. |

| Abstract: | According to the distributing characteristic of highway pivotal infrastructure,including super large highway bridge and long-span and extra-long highway tunnel etc,aimed at the traffic safety management,the concept of Dumbbell Road Network(DRN) is provided,and its boundary algorithm is especially discussed.Based on analysis of the boundary styles and constraint characteristic,the time-cost function is taken as the objective function, and Boundary algorithm of DRN is provided by mathematical derivation according to the traffic flow.Boundary algorithm is the base of the whole algorithm of DRN.Analysis Platform for determine an optimal route and network safety management is provided. |
| Keywords: | pivotal infrastructure dumbbell road network boundary algorithm |
