Real-Time System Management Information Program
Data Exchange Format Specification and companion Guide
The Data Exchange Format Specification (DXFS) helps in the development of interoperable real-time traffic and travel information within and among public agencies, as well as with private entities to establish Real-Time System Management Information Programs (RTSMIP) by establishing a standards-based specification of key RTSMIP interfaces. The DXFS can be used to define the information exchanges across a system-to-system interface, helping the interoperability of systems. A companion document is the Guide on how to use the DXFS for specifying implementation of RTSMIP at a State or regional level.
The Real-Time System Management Information Program was included in Section 1201 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). The Real-Time System Management Information Program is to provide the capability to monitor in real-time the traffic and travel conditions of the major highways across the U.S. and provide a means of sharing these data with state and local governments and with the traveling public. A Final Rule was published on November 8, 2010, establishing the provisions and parameters for the Real-Time System Management Information Program to be established by State DOTs, other responsible agencies, and partnerships with other commercial entities. The Program is to be established on all Interstate routes within 4 years (November 8, 2014) and on other significant roadways as identified by the States and local agencies within 6 years (November 8, 2016).
The Final Rule also requests additional comments relating to the costs and benefits of the Real-Time System Management Information Program and general information about current and planned programs. The Final Rule with its questions seeking comments and the link for submitting comments by December 23, 2010 are noted below.
The Real-Time System Management Information Program provides a foundation of basic traffic and travel conditions information that may be built upon and used by public agencies, other public and private parties who may deliver value-added information products, and the traveling public. Data exchange formats will allow the information to be more easily interchanged and used among agencies and other parties.
