Analysis of the Relationship Between Urban Form Components and Car-Based Travel Demand In Selected Areas of Isfahan City, Iran

Car-based travel results in greenhouse gas emissions and air pollution, with rising carbon dioxide levels posing significant challenges for urban planning globally. Urban form components greatly influence travel demand, carbon emissions, and vehicle usage patterns. This study focuses on identifying key urban form indicators and their relationship with car-based travel demand in 43 neighborhoods of Isfahan, Iran. Using secondary data and exploratory factor analysis, the study identified neighborhood form indicators. Employing an explanatory approach and quantitative methods, data were collected from documentary and field studies. The relationships and significance between urban form components and car-based travel demand were assessed using Pearson correlation and multiple linear regression. The study identified ten indicators and six independent components: density, connectivity, land use mix, access to public transit stations, centralization, and distance to the city center, plus one dependent component, the number of private cars in use. Findings reveal that distance to the city center and residential density are key factors shaping private car usage patterns. Improving the location and density of residential development and increasing access to urban services and public transportation can reduce dependence on private cars and foster sustainable urban living.
