Matt Barrett, Los Angeles MTA, originally posted a copy of their list of transportation and transportation-related acronyms, dictionaries, glossaries, and thesauri guides to the SLA Transportation Division electronic list. Several contributors posted additional resources that were incorporated to create an enhanced list and a new subject list was also developed.

The TRB LIST Committee is delighted to make both lists available to the transportation community and deeply thanks Matt and all other contributors.
