Expanding the Concept of Mobility Culture(s) as a Driver of Transit Modal Share: Insights from a Comprehensive Analysis Based on Geographically Weighted Regression (GWR)

This paper is aimed at exploring and expanding the concept of mobility culture(s) (MC), with regard to its influence on public transportation (PT) usage share. Despite some factors being positively correlated with collective modes, the modal split is often skewed in favour of private or individual ones. To this end, a comprehensive analysis of 70 cities in Germany and Italy is conducted, employing geographically weighted regression (GWR) to assess the impact of some factors on the local share of PT. Factors examined include land use diversity, fare integration, service quality (measured as level of service), scheduling regularity and characteristics of the transit network maps. The findings of the study provide new perspectives on MC and suggest strategies for promoting sustainable and equitable transportation systems.
