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。
Traffic rules are loaded on the physical road network to distribute the right of way to traffic participants and to regulate their behavior. This loaded physical road network constitutes the traffic network in the traditional sense. Based on the physical road network, this paper uses the linear reference method to define the structure of traffic rules and establish a traffic network model based on the traffic rules. Since road marking is the carrier of traffic rules, this paper proposes the marking data model associated with the rules. The road marking database established by this method can support the derivation of traffic rules. Using the above traffic network modeling method, Road network database. The case study shows that the proposed network modeling method proposed in this paper is feasible and effective.
