| 摘 要： | 指路标志指示的信息与路网的拓扑数据、几何特征和交通网络的服务规则紧密相关。在传统的弧段—结点数据模型基础上拓展了结点—邻近结点拓扑关系,加入与交叉口相关的路网几何特征和交通网络服务规则,建立面向指路标志系统的交通网络数据模型。将这种数据模型应用于广州市城市路网的指路标志系统中,实现了城市路网指路标志的自动生成。

| Abstract: | The main function of guide signs is to inform the road users of the traffic network information,and to guide them to the destinations.Because the guide signs are deployed for the intersection,arcs that connect to the same intersection,the angles and turning relation between those arcs are the most important parts in designing the data model.A new data model for guide sign system is created based on the traditional node-arc data model.The topology structure of road network,the geometry feature around intersections and traffic rules are included in the data model.The urban guide sign system built on the above data model is illustrated as an example at last.It's believed that this data model is feasible and effective. |
