DDOT recently announced a traffic signal optimization project starting on February 28, 2014. The project will enhance traffic signals in Wards 6, 7 and 8, improving the traffic signal timing patterns at nearly 200 intersections.
Though a goal of this project is to make traffic signals safer and friendlier for pedestrians, it doesn't directly involve installing more leading pedestrian intervals. LPI's now matter to cyclists because the Bicycle Safety Act that went into effect this year lets cyclists start through an intersection when the pedestrian light is green. But the LPI is a separate program, with the list generated separately. Still, some of the intersections will get LPI if obvious conflicts are noted between pedestrian and turning movements at an intersection (from project data collection).
