In Park Slope, Brooklyn, the Department of Transportation has put forward a plan to convert a pair of two-way neighborhood avenues to one-way operation. DOT says that the plan is designed strictly "to make it safer for pedestrians crossing the street," but the noisy, fast-moving traffic that we filmed on one-way Eighth Avenue, just a block up the hill, suggests that this plan is more about moving traffic than helping kids and elderly people cross the street. Watch as we use a speed gun and a noise meter to compare one-way Eighth Avenue and two-way Seventh Avenue. Then decide for yourself: Which type of street is more conducive to neighborhood life?
