Flow chart of ESCAPE

Structure of ESCAPE
ESCAPE is composed of three program modules:
I. Main simulation program
II. Route simulation program
III.Shelter simulation program
Main simulation program requires two input data which are an inverse evacuation speed grid and
shelter information while the outputs are 1) evacuation basin presenting the evacuation zones
of the analysis area which are set for each shelter, 2) required evacuation time presenting
required time for evacuees to evacuate from any points to the designated shelter,
3) evacuation direction guiding the moving direction from any points towards the designated shelter.
Route simulation program is designed for searching the fastest path from any selected starting point towards
the designated shelter.
Shelter simulation program is the function used to evaluate the shelter capacity against the
expected number of evacuees.
Route and shelter simulation programs are the options which can be consequently computed when the outputs of main
simulation program are available.
