Kappa coefficients and observed agreement by duration of sequence. Box plots derived from cross-validation using mean, 95th percentile of speed, standard deviation and deceleration for the discriminant analysis across categories of duration of sequences. Panel A: Kappa coefficients classifying walking, bicycling, bus, train and car travels; B: Categories as in A, showing proportion agreement; C: Kappa coefficients when combining motorized traffic into one category; D: Categories as in C, showing proportion agreement.
