The validity of the influence of urban form on travel behavior has been a topic of
interest in travel behavior research . Empirical research shows that urban form influences
travel behavior causing less travel impacts . However , according to the conventional
travel impact assessment following the ITE ?s (Institute of Transportation Engineers )
Trip Generation Handbook , developments with higher levels of urban form measures
will generate a greater travel impacts because they generate higher number of trips . The
ITE Trip Generation Handbook is typically used as a guideline to estimate the number
of trips generated by a development . The hypothesis made in the present research is that
a development defined with higher levels of land use mix , street connectivity and
residential density will generate a higher number of trips because of the greater
accessibility but they will be shorter in length . Therefore , the effective distance travelled
will be less even though higher numbers of trips are generated . Considering the distance
travelled on a roadway will be an appropriate unit for measuring the travel impacts , the
research argues that VMT (Vehicle Miles Travelled ) can be a better measurement unit
than the number of trips to validate the influence of urban form on travel behavior . |
