Abstract
Nowadays, environmental issues—especially urban pollution—are among the most important topics and challenges in urban planning in major cities. A significant portion of pollution is attributed to citizens' travel behavior in response to urban form. In this context, various theories such as the low-carbon city, new urbanism, and similar concepts have emerged. This study examines the relationship between urban form and the spatial distribution of trips in the city of Tabriz. The indicators used to investigate the connection between urban form elements and urban trip generation include street density, major intersection density, access to bus stations, access to metro stations, population density, and net residential density. These variables were converted into different layers using GIS and then analyzed through the spatial autocorrelation method of Moran's I. The results of Geographically Weighted Regression (GWR) show a significant correlation between the city's spatial parameters and car-based trip generation in Tabriz. The most important spatial elements influencing trip generation are urban compactness and population density, which are the strongest explanatory factors for car-based trips in Tabriz. On the other hand, according to the final R² obtained, access to commercial activity centers, metro accessibility, and land use mix have the least impact on the distribution of car-based trips. The final results indicate that urban form elements play a role in trip generation, and urban managers can manage urban travel production by organizing these elements.
