16. Abstract

Section 1201 of SAFETEA-LU, published in August 2005, instructed the Secretary of Transportation to establish a real-time system management information program to provide, in all states, the capability to monitor, in real-time, the traffic and travel conditions of the major highways of the United States and to share that information to improve the security of the surface transportation system, to address congestion problems, to support improved response to weather events and surface transportation incidents, and facilitate national and regional highway traveler information.

In response to these requirements, U.S. Code of Federal Regulations (CFR) 23 Part 511 was developed. Title 23 CFR Part 511 requires each state to establish and operate a Real-Time System Management Information Program (RTSMIP) capable of gathering and making available the data for traffic and travel conditions. However, Title 23 CFR 511 does not require the dissemination of real-time information in any particular manner, only that the states make the information available. It also does not require states to apply any particular technology, technology-dependent application, or business model for collecting, processing and disseminating information. As a result, development of a Data Exchange Format Specification (DXFS) and implementation guidance was initiated to support the need of states for a specification that satisfies the essential elements of the rule.

In 2011, U.S. DOT began development of the Data Exchange Format Specification (DXFS) to facilitate the development of interoperable real-time traffic and travel information between public agencies, with other public agencies, and with private entities. The DXFS has been developed to assist users to specify and then develop an RTSMIP implementation.
