基于道路标线布设方案的交通路网数据库构建研究

道路标线是交通规则的载体,它们布设在物理道路网络上为交通参与者分配路权,并规范其行为。通常,称这种加载了交通规则的物理道路网络为交通路网。本文首先提出了物理道路网络的表示模型;然后结合线性参考技术,以物理道路网络为基础,构建了基于的GIS道路标线布设方案数据模型;最后,本文选取示范路网,运用道路标线布设方案数据库,进行路网交通规则的推导,构建了基于车道级路网数据模型的交通路网数据库,为交通路网数据库的构建提供了一种参考。

Transportation network database construction based on traffic markings deployment

Traffic markings that imply traffic rules are deployed on the physical road network,and assign right-of-way rules to traffic participants and normalize their behaviors.Usually,the physical road network which contains traffic rules is called transportation network.In the paper,firstly,the representation model of road network was proposed.Secondly,the data model for traffic marking deployment based on GIS platform was constructed.It was created on physical road network by using the linear reference technology.Finally,the transportation network database of the given area was established based on traffic marking deployment by the deduction of traffic rules.The proposed method could provide a reference for the construction of transportation network database.
