MPOBoundaries

A Metropolitan Planning Area (MPA) is the geographic area determined by agreement between the Metropolitan Planning Organization (MPO) for the area and the Governor, in which the metropolitan transportation planning process is carried out. MPO planning area boundaries are established according to the federal metropolitan planning regulations (23 CFR 450, Subpart C) http://www.gpo.gov/fdsys/pkg/FR-2007-02-14/pdf/07-493.pdf. The MPA must encompass at a minimum the Census Urbanized Area and the contiguous geographic area likely to become urbanized within the next 20 years. This data was constructed from the NYS civil boundary files that are owned and maintained by the New York State Office of Cyber Security & Critical Infrastructure Coordination (CSCIC). Federal regulation requires that states designate MPOs in Census Urbanized Areas with populations of 50,000 or more. MPOs are responsible for ensuring that federal-aid transportation projects in the metropolitan area result from a continuing, comprehensive and cooperative transportation planning process. New York State has thirteen MPOs.

都市规划区域（MPA）是指由该区域的都市规划组织（MPO）与州长达成协议确定的地理区域，在该区域内实施都市交通规划流程。MPO规划区域的边界依据联邦都市规划规定（23 CFR 450，子部分C）确立。具体规定可查阅http://www.gpo.gov/fdsys/pkg/FR-2007-02-14/pdf/07-493.pdf。都市规划区域至少应包括人口普查都市化区域以及未来20年内可能都市化的连续地理区域。本数据集由纽约州网络安全与关键基础设施协调办公室（CSCIC）拥有并维护的纽约州民事边界文件构建而成。联邦法规要求各州在人口达到5万或以上的普查都市化区域指定MPO。MPO负责确保都市区域内的联邦资助交通项目由持续、全面且合作的交通规划流程产生。纽约州设有十三家MPO。
