While safety improvements might have been made to our streets in recent years, transport studies also show declines in pedestrian (行人) mobility, especially among young children. Many parents say there’s too much traffic on the roads for their children to walk safely to school, so they pack them into the car instead.

Dutch authors Thalia Verkade and Marco te Brömmelstroet are bothered by facts like these. In their new book Movement: How to Take Back Our Streets and Transform Our Lives, they call for a rethink of our streets and the role they play in our lives.

Life on city streets started to change decades ago. Whole neighbourhoods were destroyed to make way for new road networks and kids had to play elsewhere. Some communities fought back. Most famously, a Canadian journalist who had moved her family to Manhattan in the early 1950s led a campaign to stop the destruction of her local park. Describing her alarm at its proposed replacement with an expressway, Jane Jacobs called on her mayor (市长) to champion “New York as a decent place to live, and not just rush through.” Similar campaigns occurred in Australia in the late 1960s and 1970s as well.

Although these campaigns were widespread, the reality is that the majority of the western cities were completely redesigned around the needs of the motor car. The number of cars on roads has been increasing rapidly. In Australia we now have over twenty million cars for just over twenty-six million people, among the highest rate of car ownership in the world.

We invest a lot in roads that help us rush through, but we fail to account for the true costs. Do we really recognise what it costs us as a society when children can’t move safely around our communities? The authors of Movement have it right: it’s time to think differently about that street outside your front door.
