ABSTRACT:
A device for determining the traffic conditions between measurement locations associated with a roadway is provided. The device includes a processor that is capable of determining when a specified measurement location is passed or traversed and measure data as well as start a time period. If a device is traveling towards another specified measurement location but does not reach the location before the time period expires, a new measurement update may be sent by the device to a server. The information in this update may be utilized by the server to determine that there is a slowdown or blockage in traffic and/or that there is a traffic jam between the measurement locations. The device is capable of receiving a traffic update(s) from the server which may specify traffic conditions between the measurement locations. The traffic conditions may indicate that there is a traffic slowdown/blockage between the measurement locations.
