The CIRTPA consists of two designated committees: the Policy Committee and the Transportation Technical Committee. The Policy Committee includes elected officials, such as county supervisors, mayors, and city council members, and city managers.  The Transportation Technical Committee is comprised primarily of technical staff members, including planners, engineers, and city administrators, representing member governments and participating agencies. The Policy Committee annually elects a chair, vice-chair, and a secretary/treasurer as officers.  The Transportation Technical Committee annually elects a chair and a vice-chair.

The CIRTPA establishes and supports other subcommittees, roundtables, working groups, and advisory committees on an as-needed basis. These groups address various transportation-related issues relevant to the CIRTPA’s responsibilities.
