Amsterdam has high pedestrian traffic, but simply replicating a feature of Amsterdam associated with walkability—e.g., its high number of relatively short blocks—may be insufficient to induce increased walking in other cities. As urbanist Mariela Alfonzo argues, our understanding of individuals' decision-making about whether to walk is insufficiently robust: some studies emphasize the role of climate conditions, others the role of recreational amenities, and so on, but walking decisions are made in complex contexts in which multiple conditions and needs inform individuals' choices.
