This paper describes how a user-oriented system for identification of public transport vehicles can be developed and evaluated. For this purpose, a vehicle design is first scaled with respect to the project requirements using a proven method and with decided consideration of customer and accessibility requirements. In a next step, it is demonstrated why the recognition of the bus by public transport users at bus stops has to be identified as critical. The following section systematically generates concepts for bus identification and presents them virtually. Finally, it is described how the concept evaluation can succeed with a pedestrian simulator and which results are obtained: For example, a number should do the primary bus identification, the route should be displayed at the boarding and the individual stop destination should be clearly highlighted on the route.
