Infrastructure of justice? Citizen participation in public transport

Co-design requires a context of design conducive to accessible solutions. The objective of co-design in public transport would be to make it more inclusive and accessible for passengers. The paper makes a critical analysis of the current structure of the industry (the design context) within the framework of John Rawls´ ideas of social justice. The paper identifies obstacles to social responsiveness that exist in the flow of decisions from user-elector to user-passenger. It proposes adjustment to the existing model to move it closer to the ideal of Arnstein´s citizen participation concept. This would improve design outcomes and ford the barrier between market and non-market elements of the transport system.
