WayOut is one of 18 programs of
the Fire Engineering software package FireWind.
The model is based on the experimental
data of dependence of the velocity of pedestrian
traffic on the density of traffic flow, as it
is disclosed in book by V.M. Predtechenskii and
A.I. Milinskii "Planning for
Foot Traffic Flow in Buildings". Amerind

Company, New Delhi, 1978. The model computes movement
time applicably to an
average street person in a mid-season dress. The
algorithm is built for merging traffic and
does not allow for dividing routes. For a situation
with multiple exits and dividing routes
a user is supposed to divide the evacuation area
into “catchments” by “watersheds”
on the
basis of psychological or other considerations
and to compute movement times for each
catchment separately. The model assumes that the
movement starts at blind ends and in
the intermediate rooms movement starts when the
first evacuees appear from the blind
ends. The model allows for up to 400 “twigs”
which represent rooms and parts of the
rooms and corridors.
The input of the program is geometrical configuration
of the building (length and width
of twigs, width of doors) and population numbers
per twig. The output is the complete
movement time from blind ends and times when each
of the twigs is vacated.
The computer implementation utilizes
user friendly features of Windows: visualization
of
the evacuation tree, animation, clipboard saving
and printing of computed results, and
spread sheet presentation of the output.
