The central point of the development and progress of the creation of smart cities, lies in digitalization's contributions to the entire city's structure and the way its public enterprises function as the foundation of a sustainable city. Learned by examples from abroad and indicators at the EU level, the city is facing a gradual digitization that is gaining momentum in today's high-tech smart cities. The subtype of smart cities includes the term smart mobility, which has the task of digitizing and modernizing the functionality of public transport as well as other environmentally friendly means of transport, such as bicycles and electric vehicles. The main task in the digitization of the company will be to raise awareness of the use of public city transport and to improve the service by introducing innovations and modernizing the fleet, stops and routes. The project development strategy will be translated by the company in cooperation with external collaborators who will be in charge of the key technical performance of its parts. This project modernizes the entire Split agglomeration, which, as part of the planned accompanying projects, will be more functionally connected to the center of the area. The highlight of the mentioned project will be the creation of an application that will enhance and consolidate all information, online purchase of tickets, and will be live connected to the vehicles and inform passengers about vehicles´ location. The novelty that this application will introduce will be e-ticketing, which will enable the public to buy tickets through the application itself. E-ticketing brings a great advantage to the speed and change of passengers in buses, because the introduction of this option will further reduce the burden of selling tickets to drivers and creating crowds at stations. Informing passengers will be further improved by installing screens at the most frequent stations about the time of arrival of the vehicle at the stop. This project gives importance to the modernization of companies in the domain of service provision (in this case, public transport) as the beginning of digitization within the city's public companies. It is predicted that other public city companies in Split will follow a similar path in order to provide better service to citizens, and through this work all the key components that make this kind of project the originator of the digital revolution in the city of Split will be processed.
