Abstract

Abstract A system for instantaneously monitoring traffic congestion including a plurality of monitoring electronic devices located in motor vehicles traveling on roadways in a selected region. Each monitoring electronic device is coupled to a GPS receiver that provides physical location to a wireless modem capable of connecting to a wireless communication network. The system also includes a central computer connected to a wide area network that is able of continuously downloading physical location information from a plurality of monitoring electronic devices also connected to the wide area network. The central computer uses a traffic monitoring software program and a mapping database containing roadway information for a region and the movement information from the monitoring electronic devices to create a continuously updated traffic congestion database. Authorized users of the system are able to log onto the central computer to a portion of the database that contains specific traffic flow and congestion information. Using the system, users are also able to obtain estimated times of arrival for a specific trip, and recommendations on alternative route information. The system can also take into consideration current or anticipated events that may affect traffic congestion.
