We must remember that the data reflect the situation in
1996 through 1997. Today, ambulances are equipped with
location technology. However, to be effectively used, loca-
tion and allocation have to be carefully planned.
In our analysis, travel from one district to another is not
relevant because the two districts are geographically remote
from one another. Ambulances can, however, travel outside
their designated polygon. One must remember that polygon
construction was based on existing call patterns. If an am-
bulance travels beyond the limits of its polygon, there is a
probability of momentary shortage of ambulances to re-
spond to calls and ambulances from adjacent polygons
might have to respond.
