THE BUILT ENVIRONMENT AND TRAVEL: EVIDENCE FROM THE UNITED STATES

US studies of land-use and travel have focused on three issues relating to the built environment: density, diversity and design. Travel demands were compared among two similar neighbourhoods: Rockridge and Lafayette in California. A criticism of matched-pair comparisons of neighbourhood prototypes is that dimensions of built environment are commingled. Studies have attempted to separate these dimensions are reviewed. Studies investigating the effects of road network designs on travel choice are described. The relevancy of empirical findings to contemporary urban transportation policy themes in the USA is considered with reference to implementation tools and travel model refinements.
