Abstract
The values for perception-reaction (PR) times for highway design and operations have been well documented. However, no final agreement on what values should be used for various design purposes has been presented. In this article, the previous work on the assessment of appropriate PR times is reviewed. The influence of varying PR times on the determination of Case III ISD values is analyzed to determine whether the designer needs to be concerned about the selection of exact PR times. Basing from the conclusions derived, it is suggested that the current values for PR time for Case III ISD applications be retained.
