摘要
根据高速公路及关联路网所承担的交通功能与和结构组成,提出了三种具有典型特征的路网模型,即单通道路网、双通道路网、多通道路网。运用综合距离法以道路等级、车道数、道路里程、与主线的互通性以及与主线的距离等5个参数为指标对单通道路网并行辅助线的关联度进行了评价和排序。以各条并行辅助线实时可承担的最大交通量大于主线两点间高峰小时交通量为标准确定了路网的边界,并用图论模型对所建路网进行了简化。此外,将区域高速公路安全管理网络的构建方法在广东某高速上进行了应用。
According to the traffic function and structural composition that highway and associated road network commitment,Three typical characteristic network model,the single-channel,double-pass and multi-pass road network were proposed.A synthetical distance method was used for estimating the correlation of parallel auxiliary lines in single-channel road network.Road grade,number of lanes,road mileage,interoperability with the main line,and distance with the main line etc.indicators were raised to sort the correlation.Boundaries of the road network were defined by the criterion which real-time assumable maximum traffic in each parallel auxiliary line greater than the peak hour traffic between main line two points.The established road network was simplified by graph theory model.Besides,the method of construction traffic safety administration network in regional highway was applied on a Guang Dong highway.
