Evaluate ability to apply principles of walkable neighborhood design to balance land use, transportation, and public health. Assess understanding of mixed-use zoning, density, street design, pedestrian and bicycle infrastructure, transit access, green/open space, traffic calming, equity, and related health outcomes. Candidates should analyze a short scenario or plan, identify trade-offs, propose interventions and measurable indicators for walkability and health, and justify choices with design or policy reasoning.
