Subject: Notification of a Consultation on the Topic: Induced Travel: Does
Additional Highway Capacity Influence Travel Demand?
Dear Ms. Browner:
The Environmental Economics Advisory Committee (EEAC) of the Science Advisory
Board (SAB), met on November 12, 1999 to conduct a consultation with staff from the Office of
Policy, Innovation, and Economics (OPEI), on the topic Induced Travel: Does Additional
Highway Capacity Influence Travel Demand? At the November 12, 1999 meeting, the Agency
staff briefed the Committee on their review of recent studies of the induced travel demand
phenomenon and discussed some potential policy implications associated with this body of
literature.
The SAB has developed the consultation as a mechanism to advise the Agency on
technical issues that should be considered in the development of regulations, guidelines, or
technical guidance before the Agency has taken a position. A consultation is conducted under the
normal requirements of the Federal Advisory Committee Act, which include advance notice of the
public meeting in the Federal Register. As is our customary practice, there will be no formal
report from the SAB as a result of this consultation, nor do we expect any formal response from
the Agency.
Sincerely,
Dr. Joan Daisey, Chair Dr. Robert Stavins, Chair
