摘要 |
<p>A system (10) for instantaneously monitoring traffic congestion including a plurality of monitoring electronic devices (20) located in motor vehicles (12) travelling on roadways (14-17) in a selected region (11). Each monitoring electronic device (20) is coupled to a GPS receiver (30) that provides physical location and to a wireless modem (24) capable of connecting to a wireless communication network (40). The system (10) also includes a central computer (60) connected to a wide area network (45) that is able to continuously download physical location information from a plurality of monitoring electronic devices (20) and non-monitoring devices (22) also connected to the wide area network (45). The central computer (60) uses a traffic monitoring software program (61) and a mapping database (65) containing roadway information for the region (11) and the movement information from the monitoring electronic devices (20) to create a continuously updated traffic congestion database (64). Authorized users of the system (10) are able to log onto the central computer (60) to obtain a portion of the traffic congestion database (64) for specific traffic flow and congestion information. Using the system (10), users are also able to obtain estimated times of arrival for a specific trip, and recommended alternative route information. The system (10) can also take into consideration current or anticipated events that may affect traffic congestion.
