AGE AND DRIVER PERCEPTION-REACTION TIME FOR SIGHT DISTANCE DESIGN REQUIREMENTS
The research reported in this paper was concerned with the adequacy of the perception reaction time (PRT) assumptions for several sight distance situations. The three situations studied were: (1) intersection sight distance (ISD) for Case III (stop controlled) intersections; (2) stopping sight distance (SSD); and (3) decision sight distance (DSD). At issue was whether the value of the PRT used in AASHTO design equations was adequate to reasonably cover the range of actual driver PRTs for that situation. In particular, there was concern for the adequacy of the values for older drivers, since PRT has been shown to slow with age for a variety of tasks and situations. The study also included an experiment that compared gap acceptance judgments for older and younger groups.
