A new efficient, reliable and low-cost emergency
address dispatching and locating system has been
developed based on the Natural Area Coding System. The
principle of the system can be applied to both the map-based
address dispatching system and the computerized
address dispatching system. Both systems uses the Natural
Area Codes of addresses to dispatch addresses and let the
emergency caller or the telephone company directly
supplies the NAC of an address at which emergency
services are required, since the NAC is so useful that
everybody will know it and telephone company's address
databases will include it. If the NAC is used as the
telephone code, then the NAC will be even more easy to be
found. With the NAC, the address dispatching staff can
find the address by using a map with the NAC grid
directly. Then they can inform the emergency station
closest to the address and tell them the address and its
NAC. Or, the address and its NAC are transmitted
electronically by the telephone company to the emergency
address dispatching computer directly and the computer
will forward electronically all the information
automatically to the emergency station closest to the
address using the information supplied by the NAC.
Equipped with a map of the NAC grid or a computerized map
of the NAC grid with a route optimization function, the
driver of the emergency vehicle can use the NAC to find
out the exact address on the map and figure out the best
route to reach the location immediately. Since the driver
knows the address exactly, he/she does not need to check
street names and numbers frequently and does not need any
dispatching centers guidance. If the driver is equipped
with a GPS unit with the NAC display, the process will be
even more reliable and efficient, especially for an air
ambulance. This process may save significant time in the
emergency services and help reduce the loss of life and
property due to fire, disease and crime. The system can
overcome all the problems of current map-based and
computerized address dispatching systems.
Moreover, this
system will also save all the money invested in the large
address database set-up and maintenance. Therefore, it
is a more reliable, efficient and cost-effective address
dispatching and locating system.
This system still works
efficiently without computers since the NAC of an address
can be very conveniently found on maps of the NAC grid.
Equipped with maps of the NAC grid, the address
dispatching center and emergency vehicle driver can
dispatch and locating addresses based on the NAC of an
address told by the emergency caller. This property can
help developing countries to set up an efficient and low
cost emergency address dispatching system.
