Movement speed in main tunnel as a percentage of the desired speed (movement speed in the evacuation tunnel).

In experiment 2, the first six persons decided to run in the main tunnel and then walk in the evacuation tunnel, this allows them to achieve a higher speed in the main tunnel. We consider it as a different desired speed in different part of the tunnel, and we present two versions of experiment 2 analysis (with and without “runners”). Similarly to the assumptions in section 4.4, in results for experiment 1 we excluded the first 9 persons, who after leaving the bus, stop and discus which evacuation path to select (see.: 4.2).
