摘要

Cultural routes, once valued as heritage corridors, are increasingly experienced as tourism destinations composed of multiple attractions. Unlike work centered on tourists’ subjective motivations, this study examines how objective destination attributes shape tourist visitation along routes. Using the Kumano Kodo (Japan), 24,569 geo-tagged Flickr records quantify visitation patterns. Topic modeling of textual descriptions in the same records identifies 17 destination attributes, grouped into 4 categories. Multiple data-processing methods transformed geographic information into machine-learning-ready datasets, which are evaluated across several models. The best configuration is interpreted with PDP, heatmaps, and SHAP. Results indicate that visitation arises from combined, nonlinear attribute effects: cultural and heritage attractions function as primary anchors, tourism / commercial facilities and transport conditions provide essential support, while natural environments mainly moderate context. Attribute combinations also vary across seasons, travel modes, and visitor preferences. These findings offer practical insights and provide a transferable framework for understanding cultural-route tourism mechanisms.
