Intersection Density (Design)
- Meaning:
Intersection density measures how many street intersections exist within a given area — typically the number of intersections per square mile. - Purpose:
It reflects how connected the street network is. Areas with more intersections (especially 3- or 4-way intersections) give pedestrians more route choices and shorter travel distances to reach destinations. - Interpretation:
- High intersection density: Grid-like street patterns, easy pedestrian navigation, shorter blocks (e.g., downtowns, traditional neighborhoods).
- Low intersection density: Cul-de-sacs, disconnected streets, car-oriented layouts (e.g., suburban developments).
- Why it matters:
Greater intersection density typically means better walkability, as it encourages walking, biking, and transit use by improving connectivity and safety through slower traffic speeds.
