ABSTRACT
This chapter deals with the design and evaluation of an in-car display used to support a new version of ACC. Stop & Go ACC is an extension of normal ACC and is able to bring the vehicle to a complete stop. Previous versions have only operated above 16.25mph. The previous chapter has shown that the greatest concern for these technologies is the appropriateness of the driver’s response in any given scenario. In this chapter, three different driver interfaces are proposed to support the detection of modal, spatial and temporal changes of the system: an iconic display, a flashing iconic display and a representation of the radar. The results show that drivers correctly identified more changes detected by the system with the radar display than with the other displays, but higher levels of workload accompanied this increased detection.
