Founded in 1977, the Women's Transportation Seminar was created through the efforts of 40 women involved in transportation in the Washington, DC, area who recognized that a mechanism was needed to enhance professional and personal advancement and to develop industry and government recognition of the increasing involvement of women in the field of transportation. WTS is now an international organization of more than 4,000 transportation professionals - both women and men - with 45 chapters representing cities and states in the United States, Canada and Great Britain.
