This is the Friends email list and Google group for the Transportation Research Board Committee on Traffic Flow Theory and Characteristics (AHB45). You can find our website at www.tftc-trb.org, and our Facebook page at www.facebook.com/AHB45. Our committee relies on an active and important group of friends who participate in our meetings and webinars, serve as paper reviewers and volunteers on projects including mid-year meetings, cooperation with other committees and other special products and projects. Our Friends list currently consists of about 650 members worldwide. We hope you will join us!
