The paper presents an investigation on walking-trip generation for commuting. It uses advanced econometric models to investigate the importance of considering walking distance jointly with walking propensity in the walking-trip-generation models. Empirical models are estimated by using large-scale household travel survey data collected in the Greater Toronto and Hamilton Area (GTHA) in 1996, 2001 and 2006. Empirical models clearly validate the proposal that for walking, travel distance should be considered jointly with the propensity. The relationship between auto-ownership and walking-trip generation is proved to be very strong, referring that high auto-dependent household and neighbourhoods discourage walking. The empirical models reveal that the baseline walking propensity and distance remain unchanged over the years despite significant efforts to encourage active transportation through mixed land-use policies in the GTHA. This implies that, in addition to land-use policies, more rigorous applications of public education and social marketing are necessary.
