The establishment of a Technical Advisory Committee is required by state law dating back to the formation of the Los Angeles County Transportation Commission (LACTC), predecessor agency to Metro.

Since its formal inception in 1977, TAC has undergone periodic reviews of its membership, functions and responsibilities based upon the changing needs of this agency; however, its function remains relatively unchanged.
