  Traffic Sign Enabled Global Positioning System (GPS) Based Navigation System for Vehicles

Disclosed is a Global Positioning System (GPS) based system for alerting vehicle drivers of potential traffic violations wherein the method and system combines a GPS locating device, a digital map having relevant local traffic sign and information about traffic laws stored thereon, and readings obtained from various sensors about the vehicle, such that the system determines if the driver is about to carry out an action that is not permitted.

A GPS receiver finds and receives data from several GPS satellites. Using this data, the receiver is able to tell the user his/her location. GPS receivers in vehicles make it possible to provide a wide range of mobile e-services. GPS based navigation systems have become fairly popular. These systems consist of at least:

The GPS receiver processes signals from the GPS satellites and determines the location of the vehicle. This location is compared to the digital maps stored on the CD-ROM and the location on the map is displayed on the screen. The GPS software is typically capable of providing visual and/or voice directions to a user specified location and to points of interest such as restaurants, a gas station, etc.

The GPS applications and services that exist today for vehicles are based on navigation and assistance. For example, directions to the nearest restaurant, request for help in the event of an acciden...
