  2. V2I Communications – Major Activities Source: USDOT 2013

  3. Goal – Develop and integrate the infrastructure components necessary to provide the foundation for V2I deployment Signal Phase and Timing (SPaT) Mapping Positioning Communications Roadside Equipment (RSE) Device Integrated V2I Prototype V2I – Enabling Technologies

  4. Goal – Develop an interface between signal controllers and RSE device to enable 2-way data exchange between vehicles and controllers SPaT data Geometric intersection description (GID) Signal request messages Position correction message Standards to promote interoperability Signal Phase and Timing (SPaT) & Related Messages

  5. Past and current activities Interface testing at Safety Pilot 12 intersections equipped with Siemens and Econolite controllers Transit application using SPaT data SPaT data logged to facilitate future application development Lessons learned from Safety Pilot and other studies, and industry comment, will be used to refine the SPaT message Planned near-term steps Analyze SPaT Prototype in Affiliated Test Beds to support field testing of Multi-Modal Intelligent traffic Signal System (MMITSS) Refine SPaT and MAP messages and software to conform to final balloted version of J2735. Signal Phase and Timing (SPaT)

  6. Goal – Collect relevant roadway geometry and attributes data and broadcast It for use in V2I applications Supporting activities Initial research proved concept of generating and broadcasting maps for V2I applications LIDAR and 360 optical are promising technologies for developing the initial map; other technologies promising for map updates Mapping • Planned near-term steps • Work with ITS Standards Program to identify gaps in standards and actions going forward, and harmonize with international standards effort • Assess role in overall Digital Infrastructure initiatives.

  7. Goal – Ascertain which current or near-term positioning technologies can meet requirements of V2I applications Positioning • Current activities • Wrapping up unit testing of technologies ongoing at Connected Vehicle Highway Testbed (CVHT) located at TFHRC • GPS combined with IMU provide the best of all positioning solutions • Planned near-term steps • Complete development of positioning correction messages • Additional research at CVHT to integrated positioning technologies within the connected vehicle environment Positioning and mapping are closely related

  8. Goal – To test multiple communication technologies for potential use in V2I applications Communications • Current activities • Develop test plans to assess the most promising technologies • 5.9 GHz DSRC • Cellular 4G/LTE • Monitoring ongoing NTIA study • Planned near-term steps • Continue to investigate DSRC bandwidth issues (e.g. data transfer frequency, packet drops) using lessons learned from Safety Pilot • Document the technologies that were tested in the laboratory field test at CVHT in fall 2013 and early 2014.

  9. Goal – Foster the development of RSU device that meets the requirements of the connected vehicle program Past and current activities Hosted stakeholder workshop on August 8, 2013 Conducting weekly teleconferences Final Stakeholder conference call held in early March 2014 Version 4.0 of the specification was published on April 15, 2014 Planned near-term steps Revision to latest RSU device specification test plans Assist in setting up independent test labs for certification testing of devices Conduct functional testing of units conforming to new 4.0 specification at the CVHT at TFHRC in fall 2014. Roadside Unit (RSU) Device

  10. Goal – Develop a comprehensive prototype solution to connected vehicle infrastructure needs Incorporate all parts of track 1 to work seamlessly to enable V2I applications Integration and testing of a complete infrastructure system Data flows Information exchange Standards Current activities Architecture completed and vetted with both internal and external stakeholders. Requirements also completed and reviewed by USDOT program Managers. Integrated V2I Prototype

  11. V2I Deployment Guidance • June 2014 – Draft guidance undergoing internal review • www.its.dot.gov/arch/index.htm • Fall 2014 - Outreach workshop to stakeholders • AASHTO • World Congress • Mid 2015 - Deployment Guidance tools • End of calendar year 2015 - Entire deployment guidance package

  12. Deployment Guidance Documentation • Policy Statement • Planning • Federal-Aid Eligibility of V2I Equipment and Operations • V2I Deployments and NEPA • Interoperability • Evaluation • ITS Equipment Capability and Compatibility • Reliability • Use of Right-of-Way • Private Sector Use • Design Considerations • Use of Existing Structures and Infrastructure • Equipping Public Sector Fleets • Procurement Process • Tecnologies • Privacy • Data access • P3

  13. Tools • Systems Engineering Processes • Benefit Cost Analyses • Planning Guide • Cyber-Security guide • Licensing • Equipment selection • Message format and lexicon • Lessons learned from initial deployments • Deployment warrants
