6 Calculation of tassembly

  6.1 Case 1: In this case, all the 429 persons use stair C (316 coming from above deck 8 and 133 from below) and, once arrived at deck 8, need to travel on deck 8 to reach the assembly station using either path 1 or path 2. The corresponding time is as follows:

Item Persons N Length L (m) Calculated flow Fc (p/s) Speed S (m/s) Flow time tf (s) tf = N/ Fc tassembly t = L/S Entering
Deck 8 – path 1 200 9.5 1.92 0.95 104.4 10 Assembly station
Deck 8 – path 2 249 7.5 2.4 0.95 103.9 7.9 Assembly station

  6.2 Case 2: In this case, all the persons using stair C (totalling 598), once arrived at deck 8, need to travel through on deck 8 to reach the assembly station using either path 1 or path 2. The corresponding time is as follows:

Item Persons N Length L (m) Calculated flow Fc (p/s) Speed S (m/s) Flow time tf (s) tf = N/ Fc tassembly t = L/S Entering
Deck 8 – path 1 266 9.5 2.41 0.75 110.5 12.7 Assembly station
Deck 8 – path 2 332 7.5 3.01 0.75 110.3 10 Assembly station
