2 doc.: IEEE 802.11-11/0343r0 Submission March 2011 Hitoshi Morioka, ROOT INC.Slide 2 Abstract This presentation shows a pedestrian model in crowded area for TGai.

3 doc.: IEEE 802.11-11/0343r0 Submission General Model March 2011 Hitoshi Morioka, ROOT INC.Slide 3 Transmission range of AP: r [m] Area Occupied by 1 person a*b [m 2 ] All persons move at v[m/s] to the same direction a[m] b[m]

4 doc.: IEEE 802.11-11/0343r0 Submission Arrival/Departure Rate Arrival/Departure Rate: –Arrival/Departure rate depends on the area that crosses the border of cell at a unit time. So, –Arrival/Departure rate = 2rv/ab [persons/s] March 2011 Hitoshi Morioka, ROOT INC.Slide 4

5 doc.: IEEE 802.11-11/0343r0 Submission Practical Model March 2011 Hitoshi Morioka, ROOT INC.Slide 5Hitoshi Morioka, ROOT INC.Slide 5 But usualy the corridor is narrower than the cell diameter. Arrival/Departure Rate: wv/ab Corridor Width: w [m]

6 doc.: IEEE 802.11-11/0343r0 Submission Walking Speed References Survey by Prof. Richard Wiseman (Univ. of Hertfordshire) and British Council (2007) –Fastest City (Singapore):10.55s/20m = 113.7m/min = 1.90m/s Official walking speed used in real estate ads. in Japan –80m/min = 1.33m/s Escalator –30m/min = 0.5m/s March 2011 Hitoshi Morioka, ROOT INC.Slide 6

7 doc.: IEEE 802.11-11/0343r0 Submission Example Arrival/Departure Rate Corridor Width: 30m Very Crowded (but slow) –a: 0.5m –b: 1m –v: 0.5m/s –Arrival/Departure rate: 30*0.5/0.5*1= 30 persons/s = 1800 persons/min Not so crowded (but fast) –a: 2m –b: 2m –v: 1.5m/s –Arrival/Departure rate: 30*1.5/2 2 = 11.25 persons/s = 675 persons/min March 2011 Hitoshi Morioka, ROOT INC.Slide 7

8 doc.: IEEE 802.11-11/0343r0 Submission Questions & Comments March 2011 Hitoshi Morioka, ROOT INC.Slide 8

9 doc.: IEEE 802.11-11/0343r0 Submission Straw Poll 1 Do you believe that this pedestrian model is appropriate in train station use cases? Yes: No: More Discussion: March 2011 Hitoshi Morioka, ROOT INC.Slide 9

10 doc.: IEEE 802.11-11/0343r0 Submission Straw Poll 2 Do you believe that these parameters is appropriate? Yes: No: More Discussion: March 2011 Hitoshi Morioka, ROOT INC.Slide 10
