摘要: 根据交通管理的需求,选择行车道作为道路网络的最小建模单元,提出了一种新的基于行车道交通路网模型。 模型利用几何和逻辑这两种网络结构,实现了道路网络几何特征表达和拓扑连通关系的分离;利用两层路网结构实 现道路网络的多尺度表达;最后应用该模型讨论了移动对象的时空管理并以实例对模型进行了验证。

关键词: 行车道, 数据模型, 道路网络, 移动对象

Abstract: According to the requirements of transportation management,a new carriageway-based road network data model by selecting carriageway as minimum modeling unit was built. In the model,geometry network and logical network were used to separate geometry features and connectivity relationships of road network; two-level network structures were built to satisfy the multi-scale representation of road network. Finally,a spatial-temporal data management method for mobile objects was introduced based on the above data model and an example was presented to verify the presented model.

Key words: carriageway, data model, road network, mobile objects
