E. Integration of AHP with Dijkstra
To combine AHP weighting factors with Dijkstra into GIS,
each road length should be redefined in the minimal travel
time model for emergency routing. And the combination of
the weighting factors with the road length, or arch length in
Dijkstra’s graph, is to compromise the impedance factor for the
emergency routing, which results in the minimal travel time
model. The concept of integrate AHP into classical Dijkstra
in GIS was presented as the following Fig. 2.
