In the final paper the solution based on Web application was described and made for multimodal travel planning in the area of Zadar. In Croatia, there are very few such solutions (the example is ZET travel planning in the area of Zagreb). Because of that, the main goal is to demonstrate possibilities of applying such services in a real environment. First, there were described the meaning and types of multimodal travel planners. After that, with the technologies that were used for creation of travel planners, there were also described the process of collecting vital informations for travel planning and implementation of those informations in database. GTFS specification of transit data was also described with its creation and appliance in practical part of paper. It is very important to describe algorithm that was used in the process of routing because it represents the base of practical part of paper, so the most of effort was invested in description and comparison of algorithms which would be good candidates for construction of the solution. The process of implementation of the selected algorithm in practical work was also described. The paper as whole describes a given topic on the theoretical and practical level, and as a result provides finished solution of multimodal travel planning based on modern technologies.
