MobilityHubs_poly_scag

The purpose of this dataset is to display and include the final results of SCAG's Mobility Hubs research and the prioritized locations that emerged from that project. The locations selected fit the criteria for existing and future mobility hubs.SCAG’s mobility hubs strategy identifies mobility hub locations across the region and establishes a recommended baseline for a mobility hubs network. The data-driven methodology for screening and prioritizing mobility hubs analyzed a set of baseline network criteria using GIS analysis to determine candidate mobility hub’s locations based on proximity or inclusion within a zone. To divide the entire region into consistent land areas, counties were split into equally sized grid tiles with areas of a quarter mile by a quarter mile. The methodology established transit/rail stops as a baseline criterion, ensuring only locations containing at least one major stop were further evaluated. Other screening criteria included park and ride locations, proximity to major institutions such as sport venues, universities, and overlap with Priority Equity Communities. The screening process resulted in the identification of more than 700 potential mobility hub locations, which provided the baseline for a potential regional network. These mobility hub locations were then categorized by typology. In developing typologies, SCAG considered land use densities, transportation characteristics, and future population and employment growth. A total of six typologies were developed including: Downtown Hubs, Urban Hubs, Emerging Urban Hubs, Suburban and Rural Hubs, Equity Hubs, and Institutional Hubs. The expansive list of screened mobility hubs was then subjected to prioritization based on the following weighted criteria: transit access and connectivity, climate action, and equitable mobility. The prioritization process resulted in a halving of the prior list, to a total of 346 mobility hubs. Each of the mobility hub types has designated land uses based on definitions as well as transportation features. In addition to existing land use and transportation characteristics, each hub type includes a list of elements that are highly recommended, recommended, or not applicable (e.g., electric vehicle charging, bike share, etc.). It is important to note that design and access elements can vary significantly based on topography, property lines, and other local context factors.Data was gathered from Caltrans Park and Ride data, LA Metro boardings/alightings and bikeshare, and Homeland Infrastructure Foundation-Level Data (HIFLD). SCAG specific data included bike routes, livable corridors, microtransit service zones, SPZs 2016 and 2045, EV charging zones, airports, job centers, and Priority Equity Communities. Mobility hub identification was conducted in 2024.SCAG Mobility Hub TypesLegendMobility Hub Types Downtown HubsDowntown hubs are located in areas that have the highest employment and residential densities with a variety of high-capacity transportation and other mobility options that are easily accessible. They are located in walkable, bike-friendly areas and serve as commercial and cultural activity centers.Urban HubsUrban Hubs are located in areas that have moderate to high employment and residential densities. They contain a rich mix of high-capacity transit, frequent bus service, and access to bikeshare, carshare, and other mobility options. The built environment is walkable and bike-friendly.Emerging Urban HubsEmerging Urban Hubs have low to moderate employment and residential densities with access to high-capacity transit and local bus service, as well as limited share mobility services. These are smaller communities with low to moderate economic activity.Suburban & Rural HubsSuburban Hubs are located in areas that have land uses with relatively low employment and residential densities, and medium population and/or employment numbers today or in the future. These communities may be within driving distance to commuter rail, park-n-ride lots, local bus routes, and carshare. Rural Hubs may have rideshare or vanpool.Equity HubsEquity Hubs are located in moderate to high residential density areas which are communities of concern, and which may find elevated benefits from reliable transit service, bus routes, or shared mobility.Institutional HubsInstitutional Hub Institutional Hubs are large trip generators including universities, hospitals, stadiums, airports, and employer campuses. They may be located in a variety of environments including areas with high-capacity transit service and local bus routes. They tend to be removed from other high-intensity uses and can be challenging to access.本数据集旨在收录并展示南加州政府联盟（SCAG）交通枢纽（Mobility Hubs）研究的最终成果，以及该项目产出的优先选址列表。所选选址均符合现有及未来交通枢纽的认定标准。 SCAG的交通枢纽战略明确了区域内的交通枢纽选址，并为交通枢纽网络建立了推荐基准框架。 本项目采用数据驱动的方法开展交通枢纽的筛选与优先级排序：通过地理信息系统（Geographic Information System，简称GIS）分析，基于邻近性或区域纳入规则确定候选交通枢纽选址；为统一划分全域土地，将各区县划分为边长四分之一英里的等尺寸网格瓦片。该方法将公交/铁路站点设为基准标准，仅保留至少包含一个主要站点的地点进入后续评估；其余筛选标准还包括停车换乘（Park and Ride）点位、靠近体育场馆、大学等大型公共机构，以及与优先公平社区（Priority Equity Communities）的重叠区域。 本次筛选共识别出700余个潜在交通枢纽点位，为潜在的区域交通枢纽网络奠定了基准。 随后，研究团队依据类型学对上述交通枢纽点位进行分类。在构建类型学时，SCAG综合考量了土地利用密度、交通特征以及未来人口与就业增长情况，最终确立了六大类型：市中心枢纽（Downtown Hubs）、城市枢纽（Urban Hubs）、新兴城市枢纽（Emerging Urban Hubs）、郊区与乡村枢纽（Suburban and Rural Hubs）、公平枢纽（Equity Hubs）及机构枢纽（Institutional Hubs）。 针对上述经筛选的庞大枢纽列表，研究团队依据以下加权标准开展优先级排序：公交可达性与连通性、气候行动、公平出行。本次优先级排序将候选列表缩减一半，最终确定346个交通枢纽点位。 各类交通枢纽均依据定义及交通特征划定了对应的土地用途。除现有土地利用与交通特征外，每类枢纽还包含一份按优先级划分的设施清单，分为强烈推荐、推荐及不适用三类（例如电动汽车充电设施、共享单车服务等）。需特别说明的是，枢纽的设计与可达性元素会因地形、地界及其他本地环境因素存在显著差异。 本数据集的数据来源包括加州交通局（Caltrans）停车换乘数据、洛杉矶大都会公交系统（LA Metro）的客流上下客量及共享单车运营数据，以及国土基础设施基础级数据（Homeland Infrastructure Foundation-Level Data, HIFLD）；SCAG自有数据则涵盖自行车路线、宜居走廊、微公交服务区、2016与2045年专项规划区（SPZs）、电动汽车充电区、机场、就业中心及优先公平社区。交通枢纽的识别工作于2024年完成。 SCAG交通枢纽类型说明 ### 交通枢纽类型 1. 市中心枢纽（Downtown Hubs）：市中心枢纽位于就业与居住密度最高的区域，拥有多种便捷可达的大容量交通及其他出行选择，地处步行友好、骑行友好的区域，是商业与文化活动的核心节点。 2. 城市枢纽（Urban Hubs）：城市枢纽位于就业与居住密度中至高的区域，配备丰富的大容量公交、高频巴士服务，可使用共享单车、共享汽车及其他出行方式，建成环境具备良好的步行与骑行友好性。 3. 新兴城市枢纽（Emerging Urban Hubs）：新兴城市枢纽的就业与居住密度为低至中等水平，可使用大容量公交与本地巴士服务，以及有限的共享出行服务，属于经济活动规模较低至中等的小型社区。 4. 郊区与乡村枢纽（Suburban & Rural Hubs）：郊区枢纽位于就业与居住密度相对较低、当前或未来人口及就业规模中等的区域，此类社区可驾车抵达通勤铁路、停车换乘场地、本地巴士线路及共享汽车服务点；乡村枢纽则可提供顺风车或合乘班车服务。 5. 公平枢纽（Equity Hubs）：公平枢纽位于中至高居住密度的关注型社区，可靠的公交服务、巴士线路或共享出行可为这类社区带来显著的出行效益提升。 6. 机构枢纽（Institutional Hubs）：机构枢纽属于大型出行发生源，包括大学、医院、体育场、机场及雇主园区，可位于大容量公交及本地巴士线路覆盖的各类区域，通常与其他高强度用地相互分离，可达性相对较差。
