March 2011 doc. : IEEE 802. 11 -11/0343 r 0 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 = 2 rv/ab [persons/s] Submission Slide 4 Hitoshi Morioka, ROOT INC.
March 2011 doc. : IEEE 802. 11 -11/0343 r 0 Practical Model Corridor Width: w [m] • But usualy the corridor is narrower than the cell diameter. • Arrival/Departure Rate: wv/ab Submission Slide 5 Hitoshi Morioka, ROOT INC.
March 2011 doc. : IEEE 802. 11 -11/0343 r 0 Walking Speed References • Survey by Prof. Richard Wiseman (Univ. of Hertfordshire) and British Council (2007) – • Official walking speed used in real estate ads. in Japan – • Fastest City (Singapore): 10. 55 s/20 m = 113. 7 m/min = 1. 90 m/s 80 m/min = 1. 33 m/s Escalator – Submission 30 m/min = 0. 5 m/s Slide 6 Hitoshi Morioka, ROOT INC.
March 2011 doc. : IEEE 802. 11 -11/0343 r 0 Example Arrival/Departure Rate • Corridor Width: 30 m • Very Crowded (but slow) – – a: 0. 5 m b: 1 m v: 0. 5 m/s Arrival/Departure rate: 30*0. 5/0. 5*1= 30 persons/s = 1800 persons/min • Not so crowded (but fast) – – Submission a: 2 m b: 2 m v: 1. 5 m/s Arrival/Departure rate: 30*1. 5/22= 11. 25 persons/s = 675 persons/min Slide 7 Hitoshi Morioka, ROOT INC.
