Abstract
Monitoring road surface conditions using a mobile computer unit carried by a vehicle operating on a road network and adapted to detect information about the road surface conditions. The detection may be done by means of bump sensors which may also provide information on the size and the depth of the bump according to a detected shock with respect to the vehicle speed. Such information may then be transmitted to a central controller server. The central server may use the collected information for several purposes, such as help in planning maintenance of the road network; forwarded to users and vehicles for journey planning purposes; and to deviate traffic in case of extreme surface damage.
