This paper discusses the development of driver-vehicle interface (DVI) requirements for an inner-city transit bus collision avoidance system (CAS). In 1998, there were over 23,000 transit bus collisions resulting in over 20,000 injuries. Using structured interviews with transit bus operators and naturalistic observation, the transit bus operating environment was characterized. Then, a set of CAS functional requirements was generated. Lastly, a set of human factors DVI requirements for a transit bus CAS was developed. The DVI requirements focused on the physical aspects of the display and the display's cognitive demands on the bus operator.

This paper summarizes the activities and results of a preliminary human factors review for the Intelligent Vehicle Initiative (IVI) Program. The objective of the project was to identify human factors work that needs to be done early in the life cycle of the IVI program to ensure safe and well-engineered vehicles. This project was comprised of two major subtasks. Subtask 1 provided for a “Preliminary IVI Human Factors Technology Workshop” to draw together the stakeholders in the IVI program and define the technologies and the human factors issues that should be considered in developing an IVI. Subtask 2 investigated the preliminary infrastructure and human factors in-vehicle requirements for alternative candidate configurations of an IVI.
