Measured by distance and speed, today North Americans move more than ever. Movement, however, is but a means to an end; more movement is not in itself beneficial. Movement is a cost of meeting daily needs, and provided these needs are met, less movement is generally advantageous. Nevertheless, since the 1930s traffic engineers have pursued movement maximization in North American cities as if movement is an end in itself, and even as if movement is in itself freedom. The human costs have included unbearable burdens measurable as financial, health, safety, equitability, livability and environmental costs. Together these burdens impair human autonomy; that is, by constraining people’s choices about where and how to live, they diminish freedom. Automobility, promoted as a deliverer of freedom, has instead imposed car dependency, a kind of unfreedom. Paradoxically, many engineers now pursue so-called “autonomous” (robotic) driving, promising thereby to sustain unsustainable quantities of movement, when the sole worthy end of movement is not machine but human autonomy. To escape the traps that these errors set for us, we must trace them to their origins. Though engineering is defined as applied science, history reveals that the origins and persistence of prevailing traffic engineering principles lie not in scientific research but in power politics, and that such principles have more in common with religious dogmas than with natural laws. Far more practical possibilities await us when we escape the confines these dogmas impose on us and recognize movement as a secondary good that serves us only as it contributes to human autonomy.

Cities@Tufts Lectures explores the impact of urban planning on our communities and the opportunities to design for greater equity and justice with professor Julian Agyeman.
Cities@Tufts Lectures is produced by Tufts University and Shareable.net with support from Barr Foundation,
Lectures are moderated by Professor Julian Agyeman and organized in partnership with research assistants Amelia Morton and Grant Perry. Paige Kelly is our co-producer and audio editor, the original portrait of Peter Norton was illustrated by Anke Dregnet, and the series is co-produced and hosted by Tom Llewellyn.
