Human-Machine Interface Design Development for Connected and Cooperative Vehicle Features

This paper discusses the design and evaluation of a number of connected and cooperative vehicle sign designs which have been developed within the UK Connected Intelligent Transport Environment project (UKCITE). As part of the first phase of the project, the sign design of four different applications were developed and evaluated: Emergency Electronic Brake Lights, Emergency Vehicle Warning, Traffic Condition Warning, and Road Works Warning. Whereas some of the feature made use of existing signs (e.g. road works warning), other applications required new signs. Appropriateness of the signs were evaluated by 21 participants who were shown videos of relevant traffic scenarios with the different signs displayed at appropriate moments. Results are discussed in the context of their appropriateness and suggest that existing standard signs may not appropriately represent new connected vehicle features requiring new design solutions.
