• Abstract:
  Travelers on U.S. freeways could now be better-informed than ever before, because of a new federal legislation. ; The Final Rule 23 CFR 511 has mandated that after November 8, 2014, states provide real-time traveler data ; along all limited-access roadways, and that traveler information must also be provided along routes of ; significance in all metropolitan areas (with populations exceeding one million) two years after that. Furthermore, ; this law requires information be available 90% of the time, with an 85% rate of accuracy. This study was ; conducted, with the collaboration from the Illinois Department of Transportation (IDOT), to provide guidance on ; meeting the new rule effectively and quantifiably. ; To amass the necessary data, we reviewed published documents on the topic and conducted interviews and ; conference calls with stakeholders throughout the rural and urban transportation districts of Illinois to identify the ; routes that require real-time information, information sharing needs and possible changes and updates to ITS ; architectures. Moreover, an online survey was conducted to gather information on different practices addressing ; the requirements of 23 CFR 511 in other state DOTs. ; After gathering information from these sources, researchers recommended best strategies to satisfy the ; real-time traveler information dissemination requirements in Illinois. Accordingly, the routes requiring real-time ; information and the measures of effectiveness were identified, including methods to quantify accuracy and ; availability. Revisions to the ITS architectures relating to Illinois were proposed along with new interfaces that ; need to be added. ; The outcome of this study includes methods by which the quality of travel information for Illinois roadways ; can be measured by IDOT. In addition, this study proposed recommendations for archiving data, revising policy ; documents, updating ITS architectures, reviewing compliance with 23 CFR 511, and deploying infrastructure, all ; of which provide guidance towards complying with the 23 CFR 511 requirements.
