Systems and methods for monitoring vehicle sensors to determine and report road quality using a communication device are disclosed. The communication device determines the vehicle's location on a road, such as by use of a GPS-enabled head unit or similar device and appropriate mapping software. Monitoring road quality may be achieved by adding a sensor to the shocks, by use of a vertical displacement sensor present on the head unit, and the like. Various combinations of sensors may be employed. A horizontal displacement sensor may be used. The signals from the sensors are monitored by the head unit and analyzed to judge the quality of the road by the amount of vertical vibration that is encountered. This data, together with the vehicle's location, may be transmitted through a mobile network to a central server for distribution in road quality reports and to improve driving directions in mapping software.
