  1. Connected Vehicle Design Review Southwest Research Institute

  2. Agenda • Operational Concept • System Architecture • J2735 Driver • Subsystem • GUI Mockups • Device Status • TAMs • Configuration • 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 • Log Probe data to the database • Send out to C2C and Operator Map • Generate Alerts based on Probe Data • TAM • Receive TAM add/modify/delete messages • Maintain list of current messages • Notify J2735 Driver of message queue changes Connected Vehicle Design Review

  11. RSE Status Option 1: Single Device Status Connected Vehicle Design Review

  12. RSE Status Option 2: Tabular Connected Vehicle Design Review

  13. TAM CreationOption 1 Connected Vehicle Design Review

  14. TAM CreationOption 2 Connected Vehicle Design Review

  15. Manually Defined TAM Presentation Region Connected Vehicle Design Review

  16. RSE Selection in Response Plans • Recommend selection based on radius search • Device linking is direction of travel basedand could miss RSEs that need to be selected • RSEs are broadcast devices, similar to HAR • Messages can be picked up by anywhere but only displayed when the OBE is in the presentation region • Even though a vehicle receives a message, there is no guarantee they will ever enter the presentation region and display the message Connected Vehicle Design Review

  17. 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

  18. RSE Configuration – Option 1: Single Device View Connected Vehicle Design Review

  19. RSE Configuration – Option 2: Tabular View Connected Vehicle Design Review

  20. Alerting - Option 1: Through IDS Connected Vehicle Design Review

  21. Alerting - Discussion • Pros: • Familiar dialog to users • Re-use of exist GUI dialog • Cons • Requires a new IDS driver • Option 2: • WPF dialog with the same choices • Alert logging stays in CVS tables instead of IDS tables • Concept is similar to Pricing with different acknowledgement options • For demo purposes, look of alert would be similar to the other CV dialogs Connected Vehicle Design Review

  22. 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 Connected Vehicle Design Review
