The tourism industry is rapidly growing, and the massification of certain areas is jeopardising the environment. Certain roads in protected areas or near tourist attractions are experiencing an increase in traffic volumes, leading to higher pollution and noise levels and greater discomfort in the travel experience. To recommend measures intended to ensure a sustainable tourism industry without compromising the environment, it is necessary to obtain further knowledge regarding tourists' travel behaviour as it may differ from that of other travellers, i.e., tourists might choose a route based on variables other than time and cost, such as landscape or tourist attractions.

Using Geiranger Fjord in Norway as a case study, tourist route choice preferences were observed and analysed. In total, 60 routes from 12 different origins were observed based on 408 responses collected through a tourist survey administered in the summer of 2018. These data were combined with information regarding road features and the locations of tourist attractions. A path size correction logit model was selected to estimate the significant variables in the choice of one route over other routes. The results showed that tourists selected their routes mainly based on the travel time, road scenery (water bodies and forests), sightseeing places among first-time visitors, and outdoor activities among those living outside of Norway. In addition, the tourists preferred local roads, and 'caravan' tourists were more attracted to roads with fewer facilities. The findings of this study show that tourists’ route choice behaviour differs from that of other travellers. Policymakers should consider these differences to enhance transport systems. Further research should focus on incorporating these findings into a transport model to simulate tourists' travel patterns and quantify changes in traffic volumes due to different sustainable measures.

旅游业发展迅速，某些地区的大众化正在危害环境。保护区或旅游胜地附近的某些道路的交通量正在增加，从而导致更高的污染和噪音水平以及旅行体验上的更大不适感。为了推荐旨在确保可持续发展的旅游业而又不破坏环境的措施，有必要获得更多有关游客旅行行为的知识，因为它可能与其他旅行者的行为有所不同，即游客可能会根据时间以外的变量选择路线和费用，例如景观或旅游景点。

以挪威的盖朗厄尔峡湾为例，对旅游路线选择偏好进行了观察和分析。根据2018年夏季进行的旅游调查收集的408条回应，总共观察到来自12个不同来源的60条路线。这些数据与有关道路特征和旅游景点位置的信息相结合。选择了路径大小校正对数模型，以估计在选择一条路线而不是其他路线时的重要变量。结果表明，游客选择路线的主要依据是旅行时间，道路风景（水体和森林），首次来访者中的观光地点以及居住在挪威境外的人中的户外活动。此外，游客更喜欢当地的道路和“商队” 游客对设施少的道路更感兴趣。这项研究的结果表明，游客的路线选择行为不同于其他旅行者。决策者应考虑这些差异以改善运输系统。进一步的研究应集中于将这些发现纳入运输模型中，以模拟游客的旅行方式并量化由于不同的可持续措施导致的交通量变化。
