Velocity Obstacles enriching ARPA Marginal CPA a near miss ? Willem Barentsz / SPr / eNav_uW'18 2 / 18 Protected zone (similar to aviation) target has zero speed Willem Barentsz / SPr / eNav_uW'18 3 / 18 target w. course & speed CPA

  1. Velocity Obstacles enriching ARPA

  2. Marginal CPA a near miss ? Willem Barentsz / SPr / eNav_uW'18 2 / 18

  3. Protected zone (similar to aviation) target has zero speed Willem Barentsz / SPr / eNav_uW'18 3 / 18

  4. target w. course & speed CPA about nill Willem Barentsz / SPr / eNav_uW'18 4 / 18

  5. Manoeuvring Envelope providing solution space Willem Barentsz / SPr / eNav_uW'18 5 / 18

  6. more complex, two ships, no conflict Willem Barentsz / SPr / eNav_uW'18 6 / 18

  7. Same situation solution space problem space Willem Barentsz / SPr / eNav_uW'18 7 / 18

  8. Same situation rectangular manoeuvring envelope Willem Barentsz / SPr / eNav_uW'18 8 / 18

  9. Dimension protected zone 1 derived from interviews Willem Barentsz / SPr / eNav_uW'18 9 / 18

  10. AIS data Vlieland junction Willem Barentsz / SPr / eNav_uW'18 10 / 18

  11. Analysis CPA from AIS footage Willem Barentsz / SPr / eNav_uW'18 11 / 18

  12. 805 ships 2-9 sept 2016 Willem Barentsz / SPr / eNav_uW'18 12 / 18

  13. Shape and dimension of own ship’s protected zone  Needs to be flexible , depending on several factors, a.o.  Type of ship  Sailing Area  Captains orders  Idealy, you want to communicate this with the other ships around ( Maritime Cloud preferably ) Willem Barentsz / SPr / eNav_uW'18 13 / 18

  14. Anti-stress factor  Stay out of your neighbour’s protected zone  because COLREG’s seem not always adequately applied  because a complex close quarter situation leads easily to an accident Willem Barentsz / SPr / eNav_uW'18 14 / 18

  15. Research going on e.g. How does this effect Situation Awareness?  RAAK project in maritime safety (16 months left)  Partners are welcome  Ba and MSc students doing research projects  a.o. Maritime Safety, Augmented Reality and Ecological Interface Design  Partners are welcome Willem Barentsz / SPr / eNav_uW'18 15 / 18

  16. Augmented Reality pre-view 1 Willem Barentsz / SPr / eNav_uW'18 16 / 18

  17. Augmented Reality pre-view 2 Willem Barentsz / SPr / eNav_uW'18 17 / 18
