    Prioritized Crossings

  • Page 10Transportation Solutions Building Better Communities

    Prioritized Crossings

    Minor Street Intersections

    • Raised Crossings − Improved Visibility − Emphasizes Pedestrian &

    Bicycle Priority − Maintain Low Vehicle Speeds

  • Transportation Solutions Building Better Communities Page 11

    Prioritized Crossings

    Examples

  • Page 12Transportation Solutions Building Better Communities

    • Inadequate gaps in traffic • High Vehicle Speeds • Excessive Pedestrian Delay

    Prioritized Crossings

    HAWKS Signals/Pedestrian Hybrid Beacons

    Prioritized Crossings

    Morrissey Boulevard Redesign

  • Page 15Transportation Solutions Building Better Communities

    • Lower Costs than Signals • Increase Driver Yielding • Increase Safety Effectiveness • Reduce Incidence of

    Multiple-Threat Crashes

    Prioritized Crossings

    Rectangular Rapid Flash Beacon (RRFB)

    BEFORE AFTER
