  2. Presentation Overview • Architecture • Data flows for: • Probe Data • Basic Safety Messages • Traveler Advisory Messages • Interface Documents • DSRC Parameters • Discussion 2

  3. Architecture 3

  4. Data Flow: Probe Data & BSM C2C - probeVehicleData VII POC - Probe Data Service • SAE J2735 • ProbeVehicleData • BasicSafetyMessage 4

  5. Data Flow: Traveler Advisories C2C - travelerInfoMsgData VII POC - AMDS • SAE J2735 • TravelerAdvisory • TravelerInformation 5

  6. DSRC Parameters • PSIDs: TBD (make them configurable) • Message Transmission Frequencies: • Probe data (IPv6): algorithm defined in SAE J2735 • Traveler Advisories (WSM): 1 Hz • BSMs (WSM): 10 Hz • No 1609.2 Security • Channels: • CCH: Traveler Advisories & BSMs • SCH: Probe Data 6

  7. Other Data Available via C2C • Roadway Network • Current Conditions (Speed, Volume, Occupancy) • Travel Times • Locale Data • Roadway Inventory • Location Inventory • Events • Events Messages (incidents, closures, weather alerts) • Floodgate Messages • Field Devices • DMS • CCTV • Environmental Sensors • HAR

  8. Data Flow: C2C • Plug-in would have to be developed per application • Makes calls to web services • Push or Pull data from SunGuide

  9. Plug-in Complexity • What is needed to receive data? • Log In • Subscribe to Data (asynchronous updates for data) • Parse received XML based on C2C format • Keep Alive Call (to keep connected) • What is needed to push data? • Generate XML based on C2C data format • Send Initial Status • Send Updates • Send Deletions (if data will be no longer available) • Keep Alive (to keep connected)

  10. Interface Documents • Vehicle-to-Infrastructure • VII PROOF-OF-CONCEPT DSRC MESSAGE SETS, September 7, 2007 • SAE J2735 DSRC Message Set Dictionary, v2009-11 • NTCIP C2C • FDOT Center-to-Center Status Interface Control Document, v5.1 • SDN • Probe Data Service User’s Guide, Release 1.0, November 16, 2007 10

  11. Discussion / Questions 11
