I noticed the other day that CDOT had adjusted traffic lights at a couple intersections on my street to give pedestrians a few seconds head start to begin crossing before cars get a green light. This is called a Leading Pedestrian Interval, or LPI (check out this Streetsblog video about LPIs). This is one of those many progressive things I've read about other cities doing and wished I'd see at home. So I'm happy to see this tool being used in Chicago as the city learns that pedestrians should be the priority on our streets.
