SAFETEA-LU Section 1201 declared that ◦ Secretary shall establish a real-time system management information program (RT RTSMIP) IP) 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 ◦ Secretary shall establish data excha change nge forma rmats ts to ensure that the data provided by highway and transit monitoring systems, including statewide incident reporting systems, can readily be exchanged across jurisdictional boundaries, facilitating nationwide availability of information.
Establishes “provisions and parameters for the RTSMIP for State DOTs, other responsible agencies, and partnerships with other commercial entities in establishing real-time information programs that provide accessibility to traffic and travel conditions information by other public agencies, the traveling public, and by other parties who may deliver value-added information products”.
Construction activities that impact travel conditions, particularly lane and roadway closures; Roadway or lane blocking traffic incident information; Roadway weather observations; and Travel times or speeds for limited access roadways in metropolitan areas. 4

Specification of Data Formats to support exchange of data from highway and transit monitoring systems- primary project output Use Systems Engineering Process to define Needs, Requirements, and Design to implement the RTSMIP Based on existing ITS standards (rather than creating new standards)
Final output of project will be a guidance document for public agencies and private organizations with recommendations for how to move toward full implementation of Data Exchange Formats. Document will include: ◦ Process for implementing the data exchange formats; ◦ Discussion on testing for conformance to the data exchange formats; and ◦ Discussion on how to confirm that the agency fulfills the requirement of Section 1201.
Defined through stakeholder interviews, user needs meeting and Concept of Operations Walkthrough Cover following areas: ◦ Travel Time ◦ Incident Information ◦ Construction Information ◦ Weather Information ◦ Transit Information ◦ Roadway Network
Speed Data for Roads Travel Time Data for Roads Speed Data for Public Traveler Information Providers Travel Time Data for Public Traveler Information Providers Travel Time Data for Parties who Create Value added Information Products Transit Vehicle Travel Time
Incident Information from ◦ Public Safety ◦ Transportation Agencies for Public Safety Centers ◦ Peer Transportation Agencies Incident Information for ◦ Transit Agencies ◦ Public Traveler Information Providers ◦ Parties who Create Value added Information Products Planned Event Information
Receive Construction Info for ◦ Traveler Information ◦ Road Management Provide Construction Info to Peer Transportation Agencies and Other Parties
Collect Road Weather Environmental Conditions Data ◦ to support Traveler Information ◦ for Maintenance Operations Receive Forecasts of Upcoming Adverse Weather Related Conditions Provide Forecasts of Upcoming Adverse Weather Related Conditions Provide Road Weather Information for Peer Transportation Agencies and Other Parties
Provide Real Time Bus Locations Provide Real Time Transit Passenger Loading Provide Predicted Bus or Train Arrival/Departure times
Roadway Network and Device Information ◦ Need to have a complete definition of the road network relevant to the information received. Definition of points, links, routes, and an inventory of relevant devices
Definition of Requirements to address user needs ◦ Walkthrough of Draft Reqmts Document held on July 19 ◦ Reqmts taken primarily from TMDD Travel Time Incident Info Construction Info Weather Info Reqmts ◦ Transit reqmts generated taking into account Google Transit Real Time CEN SIRI
Design Concepts mapped to Reqmts ◦ Draft in late September ◦ Walkthrough in mid October Complete DXFS ◦ Draft in late November ◦ Walkthrough in mid December Project completed by January 2013 To participate in Walkthroughs send an email to: bruce.eisenhart@consystec.com
