Welcome to a New TRB Sponsor--South Coast Air Quality Management District
TRB is pleased to announce that the South Coast Air Quality Management District (AQMD) has become a core sponsor of TRB's programs. The South Coast AQMD is the air pollution control agency for all of Orange County, California, and the urban portions of Los Angeles, Riverside, and San Bernardino counties. TRB Core Program Sponsors are the major source of financial support for TRB's core technical activities, which include TRB standing committees and task forces, the TRB Annual Meeting, publications, online information services, and the field visit program. The goal of all of these activities is to provide opportunities for information exchange on transportation research and practice. Additional information on the TRB Core Program Sponsor program and a list of current sponsors are available online. [More] | [Share]

| Using National Household Travel Survey Data for Transportation Decision Making: A Workshop
TRB is sponsoring the National Household Travel Survey Data Workshop on June 6-7, 2011, in Washington, D.C. The workshop is designed to focus on the use of NHTS data to inform transportation decision making on key issues such as energy use, congestion, highway finance, and safety. The workshop will feature presentations and discussions on methods, examples, and techniques for using NHTS and other travel survey data to support transportation programs and decisions. Individuals or groups wishing to present at the meeting must submit an abstract of their proposed presentation by February 9, 2011. Additional information on the call for presentations is available online. [More] | [Share]
