Delays at intersections and along corridors are primarily caused by vehicles stopped at intersections. Additionally, over half of fatal and injury crashes occur within or near an intersection. Multiple modes crossing within the same intersection create multiple points of conflict that occur at high speeds. Due diligence on intersection planning, design, and improvement projects is the first step toward preventing many of these crashes. This has become especially important as alternative intersection types are becoming widely recognized. Documenting existing intersection operational and safety deficiencies leads to enhanced decision-making in the implementation of treatments to address these issues. Each intersection type under consideration has its own advantages and disadvantages, especially when accommodating vehicular, pedestrian, and bicyclist needs.
