Structural Analysis of How Urban Form Impacts Travel Demand: Evidence from Taipei

This study empirically examines the connections between urban form and travel demand at the aggregate level using traffic analysis zone data from Taipei, Taiwan, for the year 2000. Nine latent variables and 26 observed variables were analysed using structural equation modelling. By clarifying the direct and indirect effects, the empirical evidence indicates that density is positively related to trip generation and negatively associated with private mode split; mixed land use reduces trip generation and indirectly increases private mode split and a pedestrian-friendly built environment significantly reduces private mode split. Empirical evidence indicates that land use density, diversity and design affect travel demand in urban areas both directly and indirectly.
