The activities Tisar plans to carry out and the results it aims to achieve, are in line with the overall aims of the IPA Adriatic Cross-border Cooperation (CBC) Programme: to strengthen the sustainable development capacity of the Adriatic Region through an agreed strategy of actions among the partners of the eligible territories. In particular, Tisar responds to the Priority 3 of the Programme: “Accessibility and Networks”, which aims at “Strengthening and integrating existing infrastructure networks, promoting and developing transport, information and communication services”, and Measure 3.2 “Sustainable mobility systems”, which aims at improving an efficient, safe and sustainable transportation system achieving integrated development of the Adriatic area and accessibility to bordering territories. In fact, Tisar aims at creating a structured dialogue over the theme of public transport data sharing and multimodal traveller information at both political and technical level, being the final aim of the project the implementation of an ICT platform where public transport and journey planning data will be merged and made available to end users from the whole Adriatic Macro-Region. This is an issue of utmost importance for the IPA area, which presents so many differences in terms of language, culture and history. To date there is no possibility of having a single portal of information for planning a door-to-door trip within the area using a combination of public and private transport. The reasons are not only technical, but often due to lack of dialogue, and agreements and regulations at both local and international level on data sharing related to public transport. Public authorities and relevant actors from most of the countries composing the Adriatic macro-region (Italy, Bosnia, Croatia, Greece and Slovenia) will constantly interact throughout the project lifetime. A number of cross-border events, joint meetings, transfer of documentation and data will foster the capitalisation of experiences and know-how among regions presenting diverse transport policy cultures and different levels of development of ICT transport systems. The partners will jointly develop a common ICT tool for the benefit not only of the regions represented in the project but for the whole IPA area. A number of public events and communication tools are in fact envisaged to spread information about the project activities to the outside. The final tool will be at disposal of all, in all IPA languages.
