摘要
交通规则加载于物理路网上为交通参与者分配路权并规范其行为,这种加载了规则的物理路网构成了传统意义下的交通路网。本文从此含义出发,以物理路网为基础,运用线性参考方法,定义了交通规则的结构,建立基于交通规则表述的交通路网模型。由于道路标线是交通规则的载体,本文提出与规则关联的标线数据模型,以此建立的道路标线数据库,可支持交通规则的推导,运用上述交通路网建模方法,构建了车道级路网数据库。实例分析表明,本文所提交通路网建模方法是可行、有效的。
Transportation network composed of physical road network and traffic rules assigns right-of-way rules to traffic participants and normalize their behaviors. Generally speaking, transportation network is considered as physical road network loaded with traffic rules. According to this, the representation model of traffic rules was defined by using linear reference system based on physical road network, the transportation network model based on the traffic rules was proposed then. Because traffic markings imply traffic rules, the data model of traffic marking connected to traffic rules was put forward. And the built traffic marking database based on these data model can deduct traffic rules. According to this modeling method, a lane-based transportation network database was constructed from the traffic marking database. The case study illustrates that the proposed data modeling method for transportation network is feasible and efficient.
