Abstract
A system and method is disclosed for the acquisition of automobile traffic information through wireless data networks. In one embodiment, the method determines traffic conditions on roadways using a plurality of mobile communication devices. Traffic data is obtained from the mobile communication devices. The traffic data is provided to the server. The traffic data is analyzed to determine the traffic conditions.
Claims18
A method comprising:
- determining traffic conditions on roadways using a plurality of mobile communication devices comprising,
- obtaining traffic data from each mobile communication device of the plurality of mobile communication devices, wherein the traffic data includes a relative signal strength value;
- locating each mobile communication device;
- calculating a velocity of each mobile communication device by receiving the traffic data from each mobile communication device at a first time interval and at a second time interval;
- providing the traffic data to a web server;
- and
- analyzing the traffic data to determine the traffic conditions comprising,
- receiving a relative signal strength values at the web server from each mobile communication device;
- mapping with the web server, a geographic location of each mobile communication device to a street map using a database of cell locations;
- and
- counting a number of mobile communication devices passing a point during a certain time period.
