Univariate Chi square analysis and multivariate logistic regression to predict extra travel. Indendent predictors of additional distance travelled determined by general linear modelling.
^$Extra distance travelled: overall model F_13,1956 = 16.2, P < 0.001, adjusted R2 = 0.091
^$Adjusted means in the same group with the same letter do not significantly differ after post hoc analysis (Bonferroni multiple comparisons).
^Ŧall means significantly different from each other after Bonferroni multiple comparisons
