Tourists, like any other users of transport systems, seek to travel safely from origin to destination, choosing the appropriate route in relation to the speed, comfort, and cost of trip. Therefore, the goal is, from a tourism transport planning perspective, to minimize connections and, wherever necessary, make them as efficient as possible. Multimodal solutions allow passengers to adopt less polluting modes of transport whenever possible, encouraging a more sustainable journey. Digital solutions and integrated planning services offer the potential for sustainable, easy-to-use and efficient multimodal travel. The purpose of this article is to present a novel GIS-type IT solution for assessing the cost of multimodal transport to tourist resorts in Romania. The IT platform considers the movement of tourists to tourist resorts through two networks in the intermodal system, railways and national roads, connected through nodes represented by the railway stations.
