  1. Connected Vehicle Design Review • Part 2 Southwest Research Institute

  2. Agenda • Operational Concept • System Architecture • J2735 Driver • Subsystem • TSS CV Driver • GUI Mockups • Configuration • Device Status • TAMs • Response Plans • Alerting • Additional Configuration Connected Vehicle Design Review

  3. Operational Concept • SunGuide will handle specific messages from the SAE J2735 - DSRC Message Set Dictionary • Basic Safety Message (BSM) • Probe Vehicle Data Message (PVDM) • Traveler Advisory Message (TAM) • GUI • Aggregated Probe Data display • Manually create/manage TAMs by RSE • Response Plans • Pre-selects RSEs • Automatically generated presentation region Connected Vehicle Design Review

  4. Operational Concept • SDN • Send Probe data • Send TAMs • C2C • Provide demonstrators access • Probe Data • TAMs • Standard SunGuide C2C data Connected Vehicle Design Review

  5. System Architecture Connected Vehicle Design Review

  6. Architecture Diagram Connected Vehicle Design Review

  7. Driver Architecture Connected Vehicle Design Review

  8. J2735 Driver • Probe Support • Support an incoming message from RSEs • Send incoming raw Probe data to SDN • Decode Probe data • Populate into XML formatting • Send to Subsystem • TAM • Decode XML from Subsystem • Send to SDN via web service interface • J2735 Encode • Send to RSEs at regular intervals Connected Vehicle Design Review

  9. Subsystem Architecture Connected Vehicle Design Review

  10. Subsystem Tasks • Probe • Collect Probe data by RSE • Aggregate by Detection Zone • Log Probe data to the database • Send out to Databus for C2C and CV Driver • TAM • Receive TAM add/modify/delete messages • Maintain list of current messages • Notify J2735 Driver of message queue changes Connected Vehicle Design Review

  11. TSS Architecture Connected Vehicle Design Review

  12. TSS CV Driver Tasks • Tasks • Add detectors and links • Map links to detectors • Read databus for updated zone readings • Push updates to TSS for new zone data • Configuration • One detector per RSE • RSE and detector should be named the same • One link per detection Zone Connected Vehicle Design Review

  13. Special Notes on Detection Zones • Detection Zone may receive data from ANY RSE • OBE may store its data and pass it on to the next RSE • Therefore, there is no link between RSE and Detection Zone • Purely a connection for operational understanding • Zones could potentially be split away from RSEs Connected Vehicle Design Review

  14. GUI Mockups Connected Vehicle Design Review

  15. RSE Configuration Connected Vehicle Design Review

  16. RSE Configuration Connected Vehicle Design Review

  17. Optional: Configuration Inspection • This configuration is complex and may become out of sync • Tool could assist in verifying configuration • Matches RSEs to detectors • Matches Zones Ids to lanes • Checks Zone/Name mismatches for consistency Connected Vehicle Design Review

  18. RSE Status Connected Vehicle Design Review

  19. TAM Management Change Management Board

  20. TAM Editing Connected Vehicle Design Review

  21. Manually Defined TAM Presentation Region Connected Vehicle Design Review

  22. RSE Selection in Response Plans • Recommend selection based on RSE radius search • Device linking is direction of travel basedand could miss RSEs that need to be selected • RSE radius will be configured by a system-wide parameter • If RSE radius intersects the presentation region in any way, the RSE will be automatically added to the TAM Connected Vehicle Design Review

  23. RSE Selection in Response Plans • Recommend selection based on RSE radius search • Device linking is direction of travel basedand could miss RSEs that need to be selected • RSE radius will be configured by a system-wide parameter • If RSE radius intersects the presentation region in any way, the RSE will be automatically added to the TAM Connected Vehicle Design Review

  24. Automatic Presentation Region Selection • Recommend selection based on device linking • RSE does not need to be in device linking for the device linking to generate a presentation region • Region is generated by taking each involved device linking segment and extending it in all upstream directions by a configurable amount • Accurate device linking file required Connected Vehicle Design Review

  25. Automatic Presentation Region Selection • Multiple regions can be included as part of a single TAM • Auto generation would generate multiple regions • Solves issue of travelers in multiple directions Connected Vehicle Design Review

  26. Response Plan Dialog • Managed by TAM not by RSE • All aspects of the TAM can be modified before activating the response plan Connected Vehicle Design Review

  27. Alerting • Alerts for speed would be handled through TSS like all other speed alarms • Threshold would be configured on a link basis • Consistent with TSS • There would be no alerting for “TBD” fields at this time • Could be added as an enhancement when fields are better defined Connected Vehicle Design Review

  28. Additional Configuration • Config File • Driver • Port for incoming BSM and Probe Data • SDN • Host and port • URL for the TAM Interface • Admin Editor • Response Plan Template • Default Message • Amber Alert • EM • TAM presentation region offset • RSE radius Connected Vehicle Design Review
