The findings reveal that mobility scooters serve as essential tools for overcoming mobility constraints, enabling faster travel over short-to-medium distances compared to bicycles and e-bikes, and significantly expanding the accessibility of older people.

Daily travel routines derived from mobility surveys are combined with real pollution maps to compute segment-level emissions, which are then aggregated for spatial comparison and policy prioritisation. Applied to Lombardy, Italy, the method shows that although Milan and other dense cities benefit markedly, numerous peri-urban and semi-rural municipalities also show high potential due to large intermunicipal commuting flows. Overall, 13% of municipalities are classified as highest-priority areas, accounting for nearly a quarter of regional traffic-related emissions.

Validated through SUMO simulations across two scenario groups with fire origins in the northwest and southwest, we tested four evacuation strategies: simultaneous departure, temporally staggered departure, region-based evacuation with uniform response times, and region-based evacuation with realistic response time variability. Our results demonstrate that region-based, staggered evacuations with realistic response times effectively reduce peak congestion and improve safety compared to simultaneous approaches.

Women’s shorter distances and longer reservation times may lead to higher costs per kilometre under some pricing structures.
