Welcome to the home page of the Light Rail Transit Committee, formally designated as Committee AP075 of the Transportation Research Board (TRB). TRB is an arm of the National Academies of Science. The committee comprises transit professionals engaged in development, operation, and evaluation of light rail transit systems, and the purpose of this site is to facilitate the exchange of information among committee members. Here you will find a full annotated bibliography of all the published research the committee has been involved in. We also will post here calls for new research.

As we expand this site, we hope that it will assist you in your light rail transit responsibilities. We welcome your comments and suggestions. To become a friend of the group, please sign up using MyTRB. We now have a LinkedIn group! (Open to members and friends of the committee only.)
