Which street network feature most directly affects walkability and urban accessibility?

• A. The number of cul-de-sacs.
• B. The width of highways.
• C. The total length of roads.
• D. Connectivity and grid-like street networks.

Answer: (D)

Walkability and urban accessibility hinge on how easily pedestrians can move through an area using direct, safe, and legible routes. The feature that most directly enhances this is a connected, grid-like street network. When there are many intersections and short blocks, people have multiple route choices, shorter walking distances to destinations, and easier navigation. This connectivity also naturally calms traffic and creates safer, more inviting pedestrian environments.

Cul-de-sacs reduce permeability and force pedestrians to take longer, less direct routes, which hurts walkability. Wide highways can act as barriers and create unsafe crossing situations, diminishing pedestrian access. Merely having a lot of road mileage doesn’t guarantee good walking conditions; without strong connectivity, longer, meandering networks can still be inconvenient for pedestrians.
