From interfaces to infrastructure: extending ecological interface design to re-design rail  level crossings

AbstractCollisions between trains and road vehicles at rail  level crossings remain an intractable transport safety issue. This paper describes the application of Rasmussen’s ecological interface design (EID) principles to the development of a novel ‘passive’ rail level crossing prototype design and its evaluation using two driving simulator studies. Study 1 involved the design of the prototype EID crossing. Study 2 compared the EID crossing design with a standard ‘active’ rail level crossing with red flashing lights under normal conditions and Study 3 compared the crossings under conditions of driver distraction and technology failure. Th e findings show that under normal conditions, the EID crossing produced more cautious speed on approach than the standard design, but similar patterns of decision-making. Under conditions of distraction and failure, participants again demonstrated more cautious speed profiles on approach when encoun tering the EID design. Importantly, in technology failure conditions, the EID design appeared to encourage participants to engage in higher level problem-solving, which was not seen in response to the standard crossing. It is concluded that the EID crossing may be more able to support adaptive decis ion-making under conditions of failure or uncertainty.
