New York City’s Department of Transportation says redesigned streets have been very, very good to small businesses. A new report says that retail sales are up along city streets that have bike paths, pedestrian plazas, slow zones, or select bus service. In some cases, the increase is dramatic: on Brooklyn’s Pearl Street, where the DOT maintains retail sales have increased by 172 percent since a parking triangle was turned into a pedestrian plaza. In Measuring the Street, the DOT lays out metrics for evaluating street redesign projects. These include benchmarks like injuries, traffic speed and volume. And now it includes retail sales data along redesigned routes. The report casts the city’s street redesign in a favorable light just as hundreds of planners descend on the city for the Designing Cities conference, happening this week at New York University.
