Test 8: Counterflow - two rooms connected via a corridor

  12 Two rooms 10 m wide and long connected via a corridor 10 m long and 2 m wide starting and ending at the centre of one side of each room. Choose a panel consisting of males 30-50 years old from table 3.4 in the appendix to the Guidelines for the advanced evacuation analysis of new and existing ships with instant response time and distribute the walking speeds over a population of 100 persons.

  13 Step 1: One hundred persons move from room 1 to room 2, where the initial distribution is such that the space of room 1 is filled from the left with maximum possible density (see figure 2). The time the last person enters room 2 is recorded.

  14 Step 2: Step one is repeated with an additional ten, fifty, and one hundred persons in room 2. These persons should have identical characteristics to those in room 1. Both rooms move off simultaneously and the time for the last persons in room 1 to enter room 2 is recorded. The expected result is that the recorded time increases with the number of persons in counterflow increases.
