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。
Road marking is the carrier of traffic rules, which are laid out on the physical road network to assign right of way to traffic participants and to regulate their behavior. Normally, this physical road network loaded with traffic rules is referred to as a traffic network. In this paper, firstly, a representation model of physical road network is proposed. Then, based on the physical road network, a data model of GIS road markings layout plan is constructed based on linear reference technology. Finally, this paper chooses the demonstration road network and road markings layout Program database to derive the traffic rules of the road network and construct a traffic network database based on the data model of the road network with lane level to provide a reference for the construction of the traffic network database.
