The aim of this article is to examine the possibilities of introducing the MaaS model in public transport. The MaaS acronym is translated as "mobility as a service" and refers to a type of service that allows its users to plan, book and pay within a single application and its integrated platform. This model has been developing dynamically in Western European countries and North America, significantly influencing changes in user behavior (resignation from private transport in favor of effective solutions such as bicycle and scooter rentals or car-sharing services such as Uber, Bolt, etc.). In order to check the users' readiness to introduce changes in the application, a survey was conducted, which indicated the direction of action and the acceptance of the proposed solutions. Over 80% of respondents indicated interest in the application, which provides access to many transport services in the Krakow area. The article identifies public transport user problems through selected research methods. Based on the applied research models such as persona, user flows, the application interface was proposed. Then, based on the design thinking problem, further tests will be conducted to refine and improve the application interface. In the final stage - the readiness phase, the offered prototype, after the required tests and the creation of a suitable platform, will be able to be gradually implemented for use by public transport participants. Therefore, further research supporting the application prototype is recommended.
