摘要：	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.
