ABSTRACT:
A personal traffic congestion avoidance system for drivers of motor vehicles traveling on roadways in motor vehicles with GPS-based navigational systems. The system includes a GPS-based navigational system that includes a GPS receiver connected to a visual display, a map database and a wireless communication device for communicating with a remote computer over a wireless communication network. The GPS-based navigation system continuously determines the motor vehicle exact physical location in a region that is intermittently or continuously uploaded to a remote computer via the wireless communication network. The remote computer is connected to a traffic monitoring database or service that provides current traffic affecting events in the region thereto. When a traffic affecting event is located in the designated vicinity of the current location of the motor vehicle, on the current roadway used by the motor vehicle, or on a roadway that may affect the traffic on the current roadway, an alert warning is generated and delivered to the GPS-based navigational system and displayed on the visual display. The driver may ignore the warning or take an alternative route to avoid the traffic congestion.
