    Detailed Description:
    EGRESS makes use of a user defined plot plan of the structure being evacuated and

    models the movement of people, as individuals, around it. A simple example is shown.

  • In EGRESS "people" are modeled as individuals on a grid. The simulation technique
    used is based on the use of cellular automata. At each "time-step" the "people" move
    from cell to cell based on the throw of a weighed die. The weights required for the die are
    calibrated against information on speed, or flow, as a function of density, so that the
    experimental data can be adequately represented where it is valid. EGRESS has been
    validated against a range of available evacuation trials by simply drawing up the


    configurations and using all the default parameters. The agreement between the code and
    measured evacuation times was of order ±20%, except where specific features (eg. an
    aircraft over-wing exit) were not included in the default modeling. EGRESS 5.4 has a wide
    range of facilities available to account for important features and these would normally be
    used in a simulation.

    EGRESS enables an event to be mapped onto the plan to look at the impact it has on the
    available routes as the event progresses. It allows the impacts of different behaviors to be
    evaluated, as well effects of congestion and bottlenecks.

    EGRESS can model many thousands of people and several square kilometers of plan
    area, which is typically divided up into separate floor areas connected by stairways, etc.
    EGRESS has been used for a large variety of evacuation simulations ranging from
    offshore oil and gas installations, to ships, railway stations, chemical plant, aircraft, trains
    and places of public entertainment.
