ABSTRACT
This chapter describes how we used the findings from the desktop evaluation process to refine the novel rail level crossing (RLX) design concepts. It also describes an expert process that was undertaken to generate an additional two design concepts. The design refinement workshop was held approximately 6 months after the initial idea generation workshop. A booklet including the design refinement suggestions for each concept was used to present each suggestion and record the consensus of the group and the reasons for these decisions. At the conclusion of both the initial design workshop and the design refinement workshop, attendees completed evaluation questionnaires to enable us to gain their perceptions of the process. During the design refinement workshop, stakeholders accepted a proposed refinement to the Intelligent Level Crossing and the GPS Average Speed concept, which was to generate the detailed designs for the in-vehicle devices using the Ecological Interface Design (EID) approach.
