Intersection Redesign

Based on the intersection analysis, this intersection is redesigned to provide a legible, safe, and comfortable space for all users.

Design Compact Intersections

  • Break complex intersections into multiple, compact ones.
  • Minimize intersection size through the addition of curb extensions, plazas, and medians. Minimize vehicle turning speeds using medians, realignment, and small corner radii.

Simplify Geometry

  • Bend streets so that they meet at as close to a 90-degree angle as possible.
  • Maintain view corridors and sight lines for legibility and wayfinding.
  • Align crossings with pedestrian desire lines and key destinations.

Analyze Networks

  • Where traffic volume data reveals excess vehicle capacity, reduce the number of lanes along a corridor, consolidate excess turn lanes, and eliminate slip lanes.
  • Reallocate space to medians, cycle infrastructure, or sidewalks.
  • Integrate intersection design elements with the surrounding buildings and plazas.

Integrate Time and Space

  • Restricting vehicle turns at acute-angled intersections with very low volumes saves signal time and improves safety. Provide curb extensions and medians.
  • Align stop lines at all legs of the intersection to be perpendicular to the travel lanes, enhancing overall clarity and visibility for both vehicles and pedestrians.

Increase Pedestrian Space

  • Reallocate space for pedestrians and cyclists. Widen narrow sidewalks and add cycle facilities.
  • Assess and design the entire public realm in a holistic way to create one seamless pedestrian realm.
  • Introduce transit stops and other facilities at appropriate locations.

Start with Vulnerable Users

  • Realign pedestrian crossings to meet the pedestrian desire lines.
  • Add pedestrian ramps and refuge areas at crossings.
  • Reduce vehicle speeds through tighter turning radii and narrower travel lanes.
  • Provide dedicated space for cyclists.
