A collaboration including VTM’s Cristian Adorean uncovers fresh insights into the relationship between city design and travel behaviour.
A new study published in Cities examines how the layout of street networks—measured as “circuity”—relates to varied mobility cultures across 41 European cities. Co-authored by VTM senior consultant Cristian Adorean, the research explores how urban environments shape walking, cycling, and driving behaviur across distinct mobility cultures.
Circuity quantifies how indirect the road network is compared to straight-line distances. Low circuity—indicating direct routes—can reduce travel time and boost the attractiveness of active transport. The study measured circuity across walking, cycling, and driving networks in 41 cities, offering a comparative spatial lens on travel efficiency .
Beyond infrastructure, the authors developed a typology of six “mobility cultures” using socio-cultural indicators and travel patterns:
Significant differences emerged between mobility culture clusters:
The findings highlight the reinforcing effects between street structure and travel habits: direct network layouts encourage active transport, while indirect layouts create path dependence on cars.
Cristian and colleagues propose that cities aspiring to shift away from car dependence could benchmark their street layouts against low-circuity networks typical of Sustainable Transportation Advocates. This data-driven approach offers a quantitative tool to assess urban design’s alignment with sustainable mobility goals.
Cristian brings deep experience in sustainable urban transport, holding a PhD in Urban Studies and leading contributions at VTM Global in planning sustainable mobility strategies and GIS analyses. This study further strengthens VTM’s role in bridging data-driven research and transport planning practice.
This paper adds to the growing recognition of “mobility culture”— a concept emerging from Across Europe that sees personal travel as shaped not just by infrastructure but by shared values and habits. By linking network circuity to cultural patterns, this work offers urban planners a practical diagnostic and strategic tool for advancing greener, more efficient cities.
