The existence of on-street parking can change the character of a neighborhood for the better. The flow of traffic is generally slower, as motorists are more aware of cars on the road. This awareness also benefits pedestrians, who are protected by the slower speed of cars and by the separation of the sidewalk from traffic. Sidewalk activity increases, as more individuals walk from their car to their destination, resulting in a more pleasant street atmosphere and encouraging pedestrians to explore local businesses. Parallel parking is the preferred mode, but angle parking may be justifiable on streets with a greater need for parking. Parking requirements in zoning regulations should recognize on-street parking and other sources of shared public parking.
