Abstract: Based on the characteristics of the road network, the time-cost impedance model was adopted to obtain the weight of sections. Combined with the nodal efficiency values and nodal degree values, the nodal importance model of the road network was established. Considering the impact of tourist attractions on road network nodes, the degree of influence of tourist attractions on road network nodes was assessed and the guiding signs and information for tourist attractions were determined and the specific location and guidance information for setting up guide signs in tourist attractions were proposed. A visibility index model was introduced to evaluate the effectiveness of the information and location of tourist attraction signage. Finally, the surrounding road network and scenic areas of Shenmu City was taken as an example, the method for setting up guide signs for tourist attractions was verified by the case study. Research indicates that, considering the impact of tourist attractions on road network nodes comprehensively, the importance of 13 nodes in the road network has increased. The visibility index of the tourist attraction guidance signs, which is set after filtering guidance information based on node importance, reaches 0.822. The proposed method can effectively characterize the impact of tourist attractions on road network nodes. The proposed method for setting up guide signs for tourist attractions can efficiently and accurately provide guidance information to tourists.

摘要： 基于公路网特性采用时间-费用阻抗模型得到路段权重，结合节点效率值、节点度值构建路网节点重要度模型；考虑旅游景区对路网节点的影响，评估旅游景区对路网节点的影响程度并确定旅游景区指引标志指引信息，提出旅游景区指引标志设置的具体位置和指引信息；引入可视性指数模型评价旅游景区指引标志设置信息和位置的有效性；最后以神木市周边公路网及景区为例，进行旅游景区指引标志设置方法实例验证。研究表明：在综合考虑旅游景区对路网节点影响的情况下，路网中13个节点的重要度提高；基于节点重要度筛选指引信息后设置的旅游景区指引标志，可视性指数达到了0.822。提出的方法可以有效表征旅游景区对路网节点的影响，为旅游者提供高效、准确的指引信息。
