Estimating the term…
System and method for enhanced 9-1-1 address development, maintenance and call routing using road access zones (RAZs). RAZs are geographic areas accessible by a particular road. RAZs are formed from geographic data in vector form which includes a plurality of road names, address numbers, and road center lines. The steps for forming the RAZ include: first assigning a number to each road name, then creating a roadname route system based on the plurality of road names and the address numbers, then creating a plurality of polygons, wherein each polygon is associated with a different road name number, and then overlaying the road center lines with the polygons so as to define a left side and a right side of each road center line. RAZs efficiently provide for the verification, maintenance and determination of road names, address parity, geo-coding and emergency service zones (ESZ). In addition, an emergency service zone data layer (ESZ) can be created from the RAZs, which allows for, among other things, an enhanced E-911 system suitable for use with wireless communication devices, such as cell phones.
