Abstract

See full text

A server platform in the PSTN performs the service of calling the subscriber if the subscriber's customary commuting route is congested. The service makes an initial call when the fastest commute route is congested. It also makes additional calls each time it finds a better alternate route. The server can accommodate any subscriber commuting pattern. If a street on the subscriber's customary route is found to be congested, then the server sequentially tests additional streets having geographic coordinates nearby, dynamically searching for an alternate route that has an acceptable level of congestion. The server has a voice response unit (VRU) in the platform, to announce to the subscriber that the subscriber's customary commuting route is congested. Following an initial call to the subscriber, the server continues to search for better alternate routes having the least congestion and it calls the subscriber again if it finds a better alternate route.
