指路标志是一种标识路网、传递道路信息的重要交通流管控执行设施。为使指路标志携带有效信息并实现快捷诱导功能，在路网拓扑结构的基础上利用聚类分析、圈层覆盖和层次分析三种方法对基于标志性地物的指路标志设计过程进行建模，将获取的所有标志性地物数据和与之对应的道路网拓扑数据进行聚类分析，选取具有代表性的标志性地物作为指路标志的标示内容。将道路网和地物的影响范围划分为三个层次，利用圈层覆盖法确定所得标志性地物的影响范围，并将其作为标示内容的标示方向。运用层次分析法进行标示建模，确定在指路标志携带能力有限的情况下标示内容的选取优先权。最后通过算例分析验证模型的有效性。

The guide sign is an important facility to identify the road network and sending messages controlling the traffic flow .To make sure the guide sign can carry useful information achieving intelligent traffic guidance quickly ,this paper use three methods including cluster analysis ,the circle covering method and analytic hi hierarchy process (AHP) to research the guide sign based on the topology of road network and the iconic object .First ,it selects the representative object as the guiding content by cluster analysis based on the data of road network and the iconic object ;second ,it divides the road network and the influencing range of the iconic object into three levels ,then determines the guiding direction by the circle covering method;third ,it uses AHP to make decision determining the marking priority of the representative object w hich has chosen in cluster analysis ;finally ,an example to prove the model is given .
