Intersections with Dual Turn Lanes

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.
