CicLAvia transforms the urban streets of Los Angeles County by temporarily removing cars and opening the streets to people who ride bikes, walk, skate, jog or use other non-motorized transport. As a result, tens of thousands of people enjoy the health benefits offered by a public space that they would not otherwise be able to access. CicLAvia is partnering with UCLA and the Rand Corporation to measure health impacts and behavioral changes that are sparked by utilizing the city in this manner.
