Driver Characteristics at Signal-Controlled Intersections 2001-01-0045

Vehicle acceleration rates and driver perception/reaction times exist in the accident reconstruction literature. However, scant data are available characterizing drivers in “real-world” situations.
This study analyzes the perception/reaction times of drivers and initial acceleration rates of vehicles at signal-controlled intersections in “real-world” situations. Collection and assessment of these data facilitate evaluation of human factors characteristics and safety-related issues at these intersections.
The purpose of this paper is to employ a new methodology for obtaining and analyzing “real-world” driver data. These data were analyzed to determine perception/reaction time of drivers, from signal change to initial forward movement, and vehicle acceleration rates, from a stationary position.
