A Methodology for the Determination of Driver Perceptual Latency in Car Following

Abstract

An experiment was conducted to determine the feasibility of the use of motion picture testing in lieu of road testing for experiments concerning visual perceptual latency in car following. A second purpose was the determination of perceptual latencies for accelerations and decelerations at fixed speed and gap. The results show that motion picture testing is statistically acceptable. Details on instrumentation and test procedures are given and a discussion given on the findings that for the test conditions, acceleration detection time is lower than for deceleration.
