Between Atlantic Avenue and 15th Street, the road diet widened medians, shortened crossing distances, and trimmed the number of car lanes from three in each direction to two along most of the street (the northernmost blocks retained the same number of lanes). The changes were implemented using paint and flexible bollards.
After the redesign, pedestrian injuries on this stretch of Fourth Avenue fell
61 percent, total crashes dropped 20 percent, and crashes with injuries were
reduced by 16 percent, according to DOT, which compared one year of
post-implementation crash data to the prior three-year average. Read more.
