Abstract

Disclosed is a service to warn subscribers about traffic problems on their specific commute path before they approach the traffic congestion. Today drivers have to listen to radio broadcasts to find out about traffic accidents or congestion for a large region or city. This disclosure will allow users to react earlier to traffic problems in their specific area and avoid costly driving delays. This invention relies on mobile phones that can be tracked in real-time. Theses phones would contain a GPS (global positioning system) device that would transmit the phone's location back to a base station or rely on a triangulation method to pinpoint the phone's location. Using mobile phone tracking, the service provider can 1) detect congestion on the roadway and 2) identify and notify subscribers that are approaching congested areas. Notification can be through calling the subscribers mobile phone or sending a text message to the phone's screen. A database of average daily commute patterns can be used to predict the specific roads to be traveled and therefore warn the subscriber well before they would reach the traffic congestion. The warning may also include alternate routes. Process: 1) Detection of traffic congestion a) Use mobile phone tracking information and statistically determine when cars are stuck in traffic. b) Rely on other traffic monitoring providers such as radio stations or police. 2) Identify specific geographic area and roads that are affected 3) Determine which subscribers are within or approaching congested area. a) Use mobile phone tracking information to locate subscribers position and direction b) Use past historical tracking information to get subscriber's normal 1
