Abstract

Route guidance systems provide a driver with real-time, turn by turn advice to reach a selected destination. The driver uses the Driver Interface shown in Figure 1 to enter the destination in the form of an address or intersection by selecting street names from a list or typing them in on a keyboard. The Navigation Computer then calculates the route and presents a series of maneuvers as the route is traversed. The data entry can be tedious, and is prone to error if the person entering the information is unsure of or unfamiliar with the name or the spell- ing ofa street name or city.
