Major European City's Public
Transport Authority Reimagines
Self-service Ticketing through
Human-centered Design
Key highlights
Research grounded in real passenger behavior
In-depth research captured how passengers interact with ticketing machines under the pressures of a busy transit environment.
Simplified passenger journeys
We redesigned user journeys and interaction patterns to make ticket selection, fare card transactions, and payment more intuitive.
Seamless physical-digital Interactions
The experience connected on-screen instructions with the ticket machine's physical elements, helping passengers understand what to do next.
User-tested and validated design concepts
We repeatedly tested low- and high-fidelity concepts with users before handing off detailed interaction and visual specifications for development.
Summary
Reimagining self-service ticketing through human-centered design
A major European city's public transport authority wanted to improve the experience of passengers using its self-service ticketing machines. In a busy transit environment, even seemingly simple transactions can become difficult when passengers are under time pressure, unfamiliar with ticketing options, or navigating between on-screen instructions and the physical machine.
Through in-depth user research, iterative prototyping, and usability testing, we redesigned the experience around real passenger behavior, simplifying key journeys and creating clearer, more intuitive interactions between the digital interface and the ticket machine.
Client overview
Connecting millions of journeys across an integrated urban transport network
The client operates a major European area's integrated transport network, supporting millions of journeys across rail, metro, bus, and other transport services.
Self-service ticketing is an important part of the passenger experience, serving a highly diverse population, from regular commuters and fare card users to occasional travelers and visitors navigating the client's transport system.
Designing these experiences requires balancing simplicity and speed with the complexity of ticket types, payment options, physical ticketing equipment, and the demands of a busy station environment.
Challenges
Complex ticketing experience and disconnected physical-digital interactions
Self-service ticketing presents a distinctive design challenge. Passengers need to make decisions and complete transactions quickly, often in busy stations and sometimes with limited familiarity with the system.
Existing ticketing journeys had to accommodate different passenger types, ticket and fare card transactions, payment methods, and interactions that moved between the touchscreen and the machine's physical components. The station environment itself also affected passengers' willingness to engage with the kiosks.
The challenge was therefore not simply to redesign the screens. It was to understand how passengers actually behaved at the machines, identify where interactions created uncertainty or friction, and design a more intuitive end-to-end experience, all while working within the technical constraints of the existing ticketing machines.
Solution
Turning passenger insight into an intuitive ticketing experience
The team began by examining the client's behavioral studies and conducting usability research on existing self-service kiosks. This included 30 in-depth, 90-minute interviews with participants from across the city, covering rail, metro, and bus travelers as well as paper-ticket and fare card users.
The research insights were translated into low-fidelity concepts for key passenger journeys. Particular attention was given to connecting on-screen instructions with the ticket machine's physical elements, providing clearer directional cues for actions such as payment.
The concepts were progressively refined through user testing and then developed into an interactive touchscreen prototype housed within a mocked-up ticket machine. Multiple rounds of research, prototyping, and design iteration ultimately informed detailed visual and interaction specifications for development.

Business outcomes
Creating a simpler, more intuitive self-service experience
The resulting design transformed passenger research into a more intuitive self-service ticketing experience built around how people actually behave in busy transport environments.
Clearer journeys, stronger directional cues, and better integration between touchscreen interactions and the physical ticket machine helped simplify complex ticketing tasks. Iterative prototyping and user validation allowed the team to refine the experience before handing off detailed designs for development.
Most importantly, the engagement demonstrated how human-centered design can modernize an essential public service while respecting the operational and technical realities of the environment in which it must work.
