This meta-analysis shows that, consistent with prior work, vehicle miles traveled (VMT) or distance driven per capita is most strongly related to measures of accessibility to destinations and secondarily to street network design variables. Walking is most strongly related to measures of land use diversity, intersection density, and the number of destinations within walking distance. Bus and train use are equally related to proximity to transit and street network design variables, with land use diversity a secondary factor. Perhaps surprisingly, the study finds population and job densities to be only weakly associated with travel behavior once these other variables are controlled.
