- Approaching an intersection and braking to a stop, as well as accelerating from a stop, is a common occurrence in daily life. While the experience is routine, the actual rate of deceleration and acceleration has not been quantified in a naturalistic study. This paper examines the behavior of drivers at two separate controlled intersections to determine the rate at which they slow down to a stop and the rate at which they accelerate through the intersection after a signal change. The study analyzes a total of 219 vehicles decelerating and 186 accelerating. The paper will also address the acceleration rate differences of vehicles who are first to reach the intersection, compared to those that are directly behind another vehicle, as well as the lag in reaction between vehicles as they begin to accelerate from a stop.
