There is a widely acknowledged understanding that the mood and behaviours of human beings are influenced by their surroundings. That aesthetically pleasing environments and objects that are easy to use, engender a better quality of life than those that do not. This chapter examines how an attentive and progressive approach to the design of public transport infrastructure brings benefits to both passengers and operators. Contemporary discourse in the wider discipline looks upon design as both a verb and a noun and that ‘designing’ is both a form of research as well as the quality of an outcome. Something superior that has emerged from the sequencing of steps that make up a process. Drawn from the British Design Council’s Double Diamond mapping of the design process, this chapter examines each step as a research tool for the staged activities most pertinent to reach a desired outcome in the context of public transport.
