Priority Growth Areas (PGA) - SCAG Region

This is the Priority Growth Areas (PGAs) in the SCAG Region developed for Connect SoCal, the 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). PGAs include High Quality Transit Areas, Transit Priority Areas, Job Centers, Livable Corridors, Neighborhood Mobility Areas, Spheres of Influence (outside of constrained areas).High Quality Transit Area (HQTA): Generally a walkable transit village or corridor, consistent with the adopted Regional Transportation Plan and Sustainable Communities Strategy (RTP/SCS), and is within one half-mile of a well- serviced transit stop or a transit corridor with 15-minute or less service frequency during peak commute hours. Freeway transit corridors with no bus stops on the freeway alignment do not have a directly associated HQTA. Additional information on this definition is included in the Connect SoCal Transit Technical Report;Transit Priority Area (TPA): An area within one-half mile of a major transit stop that is existing or planned. This includes an existing rail transit station or bus rapid transit station, a ferry terminal served by bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods. (Based on CA Public Resources Code Section 21099 (a)(7) and CA Public Resources Code Section 21064.3);Job Centers: Areas with significantly higher employment density than surrounding areas. Over 60 subareas are identified as having peak job density and capture locally significant job centers throughout all six counties in the region;Neighborhood Mobility Areas (NMAs): Areas with high intersection density (generally 50 intersections per square mile or more), low to moderate traffic speeds,and robust residential retail connections that can support the use of Neighborhood Electric Vehicles or active transportation modes for short trips; Livable Corridors: This arterial network is a subset of the high quality transit areas based on level of transit service and land use planning efforts, with a few additional arterials identified through corridor planning studies funded through the Sustainability Planning Grant program (currently the Sustainable Communities Program); andSpheres of Influence (outside of absolute and variable constrained areas): Existing or planned service areas and within the planning boundary outside of an agency’s legal boundary; data for these areas was accessed by SCAG from each county’s Local Agency Formation Commission (LAFCO) in 2016.PLEASE NOTE this data is intended for planning purposes only, and SCAG shall incur no responsibility or liability as to the completeness, currentness, or accuracy of this information.

本数据集为南加州政府规划协会（Southern California Association of Governments, SCAG）辖区内的优先发展区域（Priority Growth Areas, PGAs），系为《Connect SoCal》项目——即《2020-2045年区域交通规划/可持续社区战略》（Regional Transportation Plan/Sustainable Communities Strategy, RTP/SCS）所编制。优先发展区域涵盖高品质公交服务区、公交优先区、就业中心、宜居廊道、社区移动区域以及约束区域外的影响范围。

高品质公交服务区（High Quality Transit Area, HQTA）：通常指符合已获批区域交通规划与可持续社区战略的步行友好型公交村落或廊道，且距离服务完善的公交站点，或高峰通勤时段发车间隔不超过15分钟的公交廊道的步行距离不超过0.5英里。高速路公交廊道若沿线未设置公交站点，则无直接关联的高品质公交服务区。该定义的更多细节可参阅《Connect SoCal公交技术报告》。

公交优先区（Transit Priority Area, TPA）：距离现有或规划中的主要公交站点步行距离不超过0.5英里的区域，包括现有轨道交通站点或快速公交站点、由公交或轨道交通服务覆盖的渡轮码头，以及早、晚高峰通勤时段发车间隔不超过15分钟的两条及以上主要公交路线交汇处。（依据《加州公共资源法》第21099条(a)(7)款与第21064.3款）

就业中心：就业密度显著高于周边区域的片区。本次共识别出60余个峰值就业密度达标片区，覆盖辖区全部六个县内的地方性重要就业中心。

社区移动区域（Neighborhood Mobility Areas, NMAs）：交叉口密度较高（通常每平方英里不少于50个交叉口）、交通车速处于中低水平，且具备完善的居住-零售接驳网络，可支持社区电动汽车或慢行交通方式完成短途出行的区域。

宜居廊道：该干道网络是基于公交服务水平与土地利用规划工作，从高品质公交服务区中筛选出的子集；另有少量干道通过可持续规划拨款项目（现为可持续社区项目）资助的廊道规划研究新增纳入。

影响范围（不含绝对约束与可变约束区域）：现有或规划的服务区域，位于管辖机构法定边界外的规划范围内。此类区域的数据由SCAG于2016年从各郡的地方机构编制委员会（Local Agency Formation Commission, LAFCO）获取。
