The difference between two routing schemes lies in the
consideration of impedance factors, such as road type, junction
delay, mass density and other factors selected in the paper.
According to the investigation on some firemen with years
experiences, the route produced by the enhanced Dijkstra
algorithm in GIS was in accordance with the fire forces’ real
route when the fire event would happen in this case. Thus the
AHP enhanced Dijkstra algorithm routing method can provide
more preferable route for emergency response, as compared
with the classical Dijkstra in GIS
