We conducted a natural experimental study of Amsterdam’s city-wide 30 km/h policy.. When cities reduce traffic speeds, people move and connect more. Amsterdam’s city-wide 30 km/h limit increased children cycling by 86% and social interactions among adults by 75% on intervention streets, showing that speed limits can shape healthier, more connected cities.
Cities urgently need systemic health checks. Without them, they keep fixing symptoms, wasting scarce budgets, while hidden risks grow. This proposed approach helps cities understand their true health and activate their self-healing capacity instead of constantly firefighting.
Air pollution threatens public health globally. Our exposure to air pollution is influenced by transport. Transport is both a prominent source of air pollution and an important determinant in our exposure to it. The built and natural environment also dictate how, when and where we travel, and what we are exposed to. We provide a comprehensive review of these relationships and their interactions.
Can Bangkok truly clean its air? New initiatives show promise, but key changes are needed. This analysis reveals how better infrastructure, stronger governance, and embracing renewable energy can pave the way for a healthier city.
Beyond the Home: This research explores how local high streets enhance older adults’ well-being by fostering social connections, a sense of place, outdoor activity, and independence, highlighting their essential role in ageing-in-place policies and urban health strategies.
We demonstrate the strong influence of neighborhood transit access and land use on driving behavior. We highlight thresholds where built environment factors significantly impact driving patterns and provide evidence for integrating age-friendly design into urban planning.
Our study provides robust, localized evidence from Srinagar, India, linking road traffic noise exposure to increased hypertension risk, particularly among women and highly stressed individuals. It highlights the inadequacy of applying high-income country data to low- and middle-income country contexts.
To understand the current drivers of air pollution, we used two natural experiments (Car-Free Day and COVID-19 Lockdown) to examine their impact on air pollution using particulate matter air pollution data in Kigali City. The health impact of non-motorized transport events in Kigali, known as ‘Car-Free Days,’ goes beyond just mass physical exercise. Importantly, it has reduced air pollution by 15%, this is expected to save more than 200 disability-adjusted life years annually.
Unregulated urbanization in Islamabad fuels flooding and health risks like dengue, revealing gaps in environmental health integration. Our study’s insights urge planners to prioritize equitable, health-focused urban policies.
This study provides critical insights into the complexity of implementing 30 km/h speeds, and opportunities to enhance systems to catalyse change.
