Human cognitive and physiological performance tends to enfeeble during time. Evidently a distinct attenuation of reaction-times spatial and situational awareness appears in the older segments of the driving population which increases rapidly in the western civilisation. Additionally, greater dependence on private automotive transportation and the unremitting raise of the elderly population, contributes to a significant increase of collision occurrences. To this end we have designed a prototype Head-Up-Display (HUD) interface which offers crucial information to the driver, in a timely manner. The interface comprises symbolic representation of the lead vehicles and road information acting as a vision enhancement system. The evaluation of the system contrasted the proposed HUD interface to the existing Head-Down Displays (HDD) offering encouraging results, with significantly decrease collision occurrences tested different accident scenarios.

This paper presents the design and development of a prototype Head-Up Display (HUD) interface that offer early notification warnings of potential collisions under unfavourable weather and traffic conditions. In this work we particularly focus our effort in the embedment of traffic congestion and sharp turn visual warnings in a working prototype interface. In turn we present the results of a large scale evaluation of the system on a group of forty users, which contrasted the use of the proposed HUD against a typical HDD. Finally the paper offers suggestions for further research and a tentative plan for future work.
