ABSTRACT

This chapter reports on work done for the Federal Highway Administration (FHWA) under a contract to investigate human factors aspects of automated highway systems design. The objective of the contract was to provide human factors input during the conceptual stages of Automated Highway System (AHS) development to affect its design and implementation and to lay the foundation for future advancement of the AHS. The chapter presents an experiment on Human Factors Aspects of Transferring Control from the Driver to the Automated Highway System with Varying Degrees of Automation. The objective of this experiment was to investigate different methods of transferring control from the driver to the AHS. Regarding a possible role for the driver under failure conditions, computer simulations were used to observe dynamic vehicle behavior over time following control actuator failures. Combined experimental and analytical data were used to investigate the throughput in an automated lane that can be expected under certain conditions.
