Potential Problems Common to Carrier Routes

Listen to what delivery workers have to say.
Trying to find one address is hard. Imagine trying to find five or six hundred.

Address-based deliveries are difficult enough under the best of circumstances. In suburban areas, the difficulty skyrockets. Roads twist and turn. East, west, north, and south mean little. Semi-private roads in subdivisions are often not shown on maps. Numerous roads may have the same name. Road signs are often missing. Using address-based systems such as postal carrier routes under these conditions is error-prone. Deliveries may easily be missed or duplicated.
 

The map on the right shows the street network for a medium sized community. The inset map above is a zoomed-in view. Imagine the difficulty in finding dozens or hundreds of address ranges or individual addresses.
In areas without rectangular blocks, grid mapping can use a number of methods to simplify routes.

The yellow inset map on the right shows the locations of homes and businesses. Using this data, route boundaries can be placed in areas of little or no population density or along physical man-made or natural features. Delivery zone 14, for example, uses the following physical boundaries: a lake, an open field, a cemetery, and a major highway. The delivery worker is simply instructed to deliver everything between those intuitive boundaries. Any new streets or subdivisions would be delivered - even if they are not yet shown on maps. These physical boundaries also reduce the chances of duplicated or overlapped deliveries.
