Intersections with dual or double turn lanes have multiple conflict points between motorists and pedestrians and have shown to result in an increased frequency of crashes. DDOT has developed a plan to improve intersections with dual-turn lanes that pose "multiple threat" risks, particularly to Pedestrians.
The Dual-Turn Conflict Mitigation Project deconflicts movements between pedestrians and turning vehicles, by either separating the pedestrian movement and dual-turns with signal timing and phasing improvements or, changing lane geometry of the turning lanes.
A total of 45 locations were identified among the 1650 signals in the city and of the 45, 31 are complete. Following is the status list of locations.
