Federal Regulation 23 CFR 511 promises to improve the traveler information that assists motorists to make better travel decisions. In accordance with this regulation, all state departments of transportation (DOTs) are required to provide real-time traveler information including construction activity, lane blocking incidents, adverse weather conditions, and travel-times on certain facilities, by November 8, 2014. In this thesis, the researcher used an online survey to collect information from State DOTs and their associated representatives from the US Federal Highway Administration (FHWA). A survey was distributed electronically to FHWA representatives, State DOT Operations Engineers, and State DOT Intelligent Transportation Systems Coordinators who were active in the implementation of their agency's real-time systems management information program. The survey results illustrated that field data was most frequently processed into travel times with software from vendors, and the majority of the agencies used the accuracy thresholds required by the new rule. According to the survey results, the most common way that DOTs gather construction lane closure information is by requiring the contractors to provide this information using existing specifications and special provisions. The survey results indicated that most of the agencies operate 24 hours a day; therefore, they do not have problems providing the incident information to the public. Overall the findings of this study are relevant to both practitioners and researchers in transportation engineering because they detail current reported practices of how DOTs are collecting, processing, and disseminating travel time, construction, incident, and weather data, and how DOTs are measuring the quality of the data.
