Park and Ride (P&R) facilities are parking lots located near transit stations or stops where commuters can leave their personal vehicles and continue their journey by public transit. These facilities encourage transit use by extending service reach to areas with limited direct transit access, reducing traffic congestion and emissions in urban cores. Park and Ride lots are common at suburban rapid transit stations, bus terminals, and carpool staging areas. Municipalities and transit authorities build and maintain these facilities, which may offer free or paid parking. Effective Park and Ride systems require convenient transit connections, adequate parking capacity, and good security.
