California Metropolitan Planning Organization (MPO)

This dataset contains the geographic boundaries of Metropolitan Planning Organizations (MPO) and is intended for metropolitan area multimodal transportation planning applications. MPOs designate the federally mandated and federally funded transportation policy-making organization in the United States. This dataset is for California only and is maintained by the Bureau of Transportation Statistics (BTS), but it has been modified by Caltrans to conform to the California County Boundary dataset. MPO organizations include representatives from local government and governmental transportation authorities and they carry out the metropolitan transportation planning process in that area.
