 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

• ther 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.

 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

• rganizations 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

• 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
