Asian cities have traditionally been cities of walkers, and many urban dwellers rely on walking, cycling and public transport for their daily travel. However, with the exponential increase in motorization, limited attention has been paid to pedestrian and public transport facilities. A change in focus is required which will allow people, not vehicles, to reclaim the urban environment. Growing motorization has also led to a dramatic increase in the number of pedestrian fatalities and accidents, and high levels of air pollution—particularly exposing pedestrians who walk to work or access public transport to reach their destinations. To raise awareness of our cities'deteriorating walkability, and with ultimate aim of promoting better air quality and livable cities, Clean Air Asia and its partners have conducted a series of walkability surveys in Asian cities.
