Donald Shoup, distinguished research professor of urban planning at UCLA Luskin, wrote a commentary for Bloomberg CityLab about how to reduce the overwhelming amount of congestion in Manhattan. A pay-to-park model that changes price depending on demand — which many motorists might find undesirable at first — would ensure that most of the curb space is well used while also leaving room for a few vacant spots, Shoup explained. “Revenue generated by the meters can be used to pay for public services, such as repairing sidewalks, planting street trees or providing other improvements,” he said. “Few will pay for curb parking, but all will benefit from public services.” The meter revenues could also be used to pay for transit passes for workers, allowing commuters who use buses to benefit as well. Shoup calculated that employing this model would allow the Upper West Side to raise $237 million every year.
