| Abstract | Braking to a full stop at a prescribed target position is a driving maneuver regularly used in experiments to investigate driving behavior or to test vehicle acceleration feedback systems in simulators. Many different performance measures have been reported in the literature for analyzing braking. These may or may not be useful to analyze the stopping maneuver, because a number of potential problems exist: 1) the scores on a measure may be insufficiently reliable, 2) the measure may be invalid, or 3) the measure may be strongly correlated with other measure(s). A simulation and an empirical study were conducted to analyze various measures. From the simulation study it is concluded that: 1) a measure based on the speed vs. time relationship can be used to measure deviations from a constant deceleration (R), 2) minimum time-to-collision (TTCmin) is sensitive to target position offsets, and 3) mean TTC-dot can capture braking behavior characteristics, but the required definition of a begin and end sample-point for its calculation is a disadvantage. The empirical study calculated a set of measures using the data of 60 participants who drove ten stopping maneuvers in a driving simulator. It is concluded that reliable and valid measures for a stopping maneuver are provided by the speed and distance to the target position at braking onset, the stopping position with respect to the target, and the R measure to measure deviations from a constant deceleration. Recommended additional measures are: the mean speed of the complete braking maneuver, stopping position consistency, maximum deceleration, and onset jerk. De Groot, S., De Winter, J. C.
