Aviation Technical Advisory Committee
The Aviation Technical Advisory Committee (ATAC) is a group of aviation professionals (e.g. airport planners, transportation agency officials, academics) who meet quarterly in an effort to provide SCAG with technical and professional expertise on regional aviation issues. Information and data provided by the ATAC to the SCAG Aviation Program is used for the aviation element of the Regional Transportation Plan, as well as other planning and research efforts.
Modeling Task Force
The Modeling Task Force (MTF) coordinates the Region’s various modeling programs and provides a forum to share model-related information, new ideas, and discuss data standards. Participation in the MTF is open to all interested parties including: governmental staff, educational related individuals/groups, environmental organizations, business groups, and the general public. The MTF is not a legislative body of SCAG, and therefore, meetings of the MTF shall not be subject to the Brown Act.

Regional Planning Working Groups
The Regional Planning Working Groups (RPWG) function as a forum for SCAG staff to engage stakeholders in the development and implementation of plans and policies to advance the region’s mobility, economy, and sustainability. Areas of focus include: Safe and Active Streets; Equity; Natural and Farm Lands Conservation; and Sustainable and Resilient Communities.
A few notes regarding participation in the meetings:
- RPWG meetings are structured as open public forums for information sharing only.
- RPWG participants do not vote or take positions on any policy issues.
- SCAG staff organize and manage the meetings, with no formal chair or assigned roles for participants.
- Meetings are open to the public and may include participation from peer stakeholders and staff from state, regional, and local agencies, non-profit organizations, local universities, and the business community.
- RPWG meetings are held remotely (via video-conferencing/teleconferencing) through the development of Connect SoCal, the 2024 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). Changes to meeting format and schedule(s) will be further communicated through each working group when applicable.
- RPWG meetings will generally be held on the third Thursdays of the month. Specific dates and times are announced at the beginning of the month. Sign up to receive monthly RPWG emails.
Regional Transit Technical Advisory Committee
The Regional Transit Technical Advisory Committee (RTTAC), made up of representatives from the Region’s transit operators, provides a forum for coordination of input in the development of the Regional Transportation Plan and the Regional Transportation Improvement Program. Past discussion topics have included funding programs, intelligent transportation systems, transit-oriented development, and performance measures.
Technical Working Group
The purpose of the Technical Working Group (TWG) for regional planning and growth is to enhance the quality, data integrity and transparency of the Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) by providing a venue for SCAG staff to discuss and receive feedback on growth-related technical approaches, data collection and technical tools associated with the development, implementation, and monitoring of the RTP/SCS with local and regional planning partners, regulatory and coordinating agencies, and technical experts. The working group shall not serve as a policy, legislative or voting body and thus meetings are not subject to the Brown Act.
