Development of a Reproduction Method of a Stream of People for Intuitively Recognize a State of Congestion

  1. 1. Development of a Reproduction Method of a Stream of People for Intuitively Recognize a State of Congestion 混雑状況を直感的に把握可能にするための人流センシング再現手法の開発 Sayoko Shimoyama, Hiroki Uematsu WORLD DATA VIZ CHALLENGE 2018
  2. 2. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 2 Congestion - one serious problem in a city
  3. 3. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 3 Japanese major cities are sometimes badly congested. This picture shows the train platform in the rush hours in Tokyo.
  4. 4. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 4 can be life-threatening accident
  5. 5. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 5 decreasing QOL of residents
  6. 6. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 6 寿司詰め Sushi-Zume (n) jam-packed; packed in like sushi (like sardines)
  7. 7. How to resolve congestion? 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 7 congestion Decentralize a stream of people Increase a capacity in a place Eliminating causes of congestion
  8. 8. How to resolve congestion? 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 8 congestion Decentralize a stream of people Increase a capacity in a place Eliminating causes of congestion Understanding of the current situation
  9. 9. Our solution helps 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 9 congestion Decentralize a stream of people Increase a capacity in a place Eliminating causes of congestion Understanding of the current situation
  10. 10. Demonstration Project in the Underground Passage in Sapporo City passage length: 520m The most longest under ground passege in japan Put sensors that were developed by Infolounge Co., Ltd at 5 point to measure the stream of people. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 10 By 663highland, CC BY 2.5 Sapporo, Hokkaido, Japan
  11. 11. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 11 Total Count 0 0 Ultrasonic Sensor ceiling
  12. 12. Detect the existence of a person by the change of the ultrasonic distance 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 12 Total Count 0 0
  13. 13. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 13 Total Count 0 0
  14. 14. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 14 Total Count 1 1Detect the moving direction by the time difference of the change of the ultrasonic distance
  15. 15. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 15 Total Count 2 1
  16. 16. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 16 Total Count 2 2
  17. 17. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 17 sensors installed on a ceiling
  18. 18. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 18 number of people who passed at a point in underground pass in 1 minute majored by sensors
  19. 19. 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 19 from station to station sum number of people
  20. 20. PROBLEM:It’s difficult to recognize the state of congestion intuitively Visualizing numerical value as a chart helps us understand the situation But it’s difficult to know how much congestion degree is there 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 20 ? Sushi-Zume Not Sushi-Zume
  21. 21. SOLUTION:Reproduce the stream of people using 3D model Reproduce the stream of people from the numeric value measured by sensors using 3D model It enables intuitively recognize a state of congestion 2018/11/14 SAYOKO SHIMOYAMA, HIROKI UEMATSU 21
