This is the High Quality Transit Areas (HQTAs) in the SCAG Region for plan year 2045, developed for the Final Connect SoCal (the 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS)). SCAG’s HQTA is within one-half mile from a “major transit stop” and a “high-quality transit corridor” and developed based on the language in SB375 and codified in the CA Public Resources Code. The definitions of a “major transit stop” and a “high-quality transit corridor” are as follows:A. Major transit stop: A site containing an existing rail or bus rapid transit station, a ferry terminal served by either a 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 (CA Public Resource Code Section 21064.3). It also includes major transit stops that are included in the applicable regional transportation. B. High-quality transit corridor (HQTC): A corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.Further explanation of the methodology for identifying HQTCs and major transit stops is included in the Connect SoCal Transit Technical Report Appendix.PLEASE NOTE that SCAG has made one modification to its methodology of HQTAs development to exclude the one-half mile areas around freeway-running HQTCs where there are no bus stops; the one-half mile areas around bus stops serving those freeway HQTCs remain.Major transit stops and HQTCs are based on the 2045 plan year transit network of Connect SoCal. PLEASE NOTE that SCAG updates its inventory of planned major transit stops and HQTCs with the adoption of a new RTP/SCS, once every four years. However, transit planning studies may be completed by transit agencies on a more frequent basis than the RTP/SCS is updated by SCAG. Users should consult with the appropriate transit provider(s) to obtain the latest information on planned transit routes, stop locations, and service intervals. 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.

Assembly Bill 2553(2024) is changing the definition of a bus major transit stop to be the intersection of two corridors with a service interval (headway) of every 20 minutes (3 trips/hr), instead of every 15 minutes (4 trips/hr). Although the bill formally takes effect January 1, 2025, this data set now incorporates this change.This means that there are now two frequency standards captured by this data set:4 trips/hr (15min headway) for high quality transit corridors, as well as bus rapid transit (BRT) major stops (along with other requirements for BRT)3 trips/hr (20min headway) for bus corridors intersecting to form a bus major stopWith this change, bus major stops are no longer a subset of high quality transit corridors, since the intersection of two corridors with frequencies of 3 trips/hr now creates a major stop despite neither being a high quality transit corridor.For information on how Caltrans developed the source data, and to access the complete data set, please visit the High Quality Transit Areas Analysis Open Data Portal.

Use GTFS schedule trips, stop_times, shapes, and stops to estimate whether corridor segments have scheduled frequencies of 15 minutes or less.

High Frequency Transit Areas (HFTAs) are areas of the region within one-half mile of a major transit stop (existing or planned light rail, streetcar, or train station) or an existing or planned high-quality transit corridor included in the MTP/SCS. A high-quality transit corridor is a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours. SACOG uses this definition of HFTAs because it coincides with the definition of Transit Priority Projects in SB 375. Under SB 375, Transit Priority Projects are eligible for streamlined environmental review.

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.

This dataset includes geographic areas that meet location eligibility criteria for Transit Priority Projects, as defined in California Public Resources Code (PRC) - Section 21155.1, consistent with Senate Bill 375 and Plan Bay Area 2040 (official): Within ½ mile of a Major Transit stop , defined as any of the following:-Existing rail stations-Planned rail stations in an adopted Regional Transportation Plan (RTP)-Existing ferry terminals with bus or rail service-Planned ferry terminals with bus or rail service in an adopted RTP-Intersection of at least two existing or planned bus routes with headways of 15 minutes or better during both the morning and evening peak periods; orWithin a ¼ mile of a High-Quality transit corridor , defined as an existing or planned fixed-route bus corridor with headway of 15 minutes or better during both the morning and evening peak periods. Note that to qualify as a Transit Priority Project, a development proposal must also comply with the full set of land use, density, environmental criteria included in the California Public Resources Code, Section 21155(b) This dataset was developed using several data sources that include Planned Transit Systems identified in the Plan Bay Area 2040 Regional Transportation Plan, Existing Transit locations extracted from the 511 Regional Transit Database, and manual editing conducted by the Spatial Modeling team at MTC.See further details here: https://bayareametro.github.io/Data-And-Visualization-Projects/legislative_transit_data.html

Priority Development Areas were locally defined and used by the Metropolitan Transportation Commission and Association of Bay Area Governments to identify future growth areas in the proposed Plan Bay Area 2040 Transportation Plan, Transit Priority Areas (TPAs) are defined by SB 375 as areas within half a mile of a major transit stop or high quality transit corridor, amongst other criteria. TPA corridors generally include existing neighborhoods served by transit, and contain a wide range of housing options along with jobs, schools, and amenities. Under SB 375, certain residential or mixed use residential projects and projects located within TPA corridors that meet defined criteria may be eligible for California Environmental Quality Act streamlining.
