  6. 5. Algorithm evaluation for road anomaly detection and wear estimation on trucks using an accelerometer

    University essay from KTH/Fordonsdynamik

    Author : Goran Spiric; [2014]
    Keywords : ;

    Abstract : The condition of the roads is a factor that may not only affect the wear of a vehicle, car or truck, but as well may reduce fuel consumption, increase comfort, lower noise and maybe most importantly increase traffic safety. This gives a need of a system that can measure road quality and detect potholes, which could be of interest to haulers and to local road authorities that would get valuable information of road sections that are in need of maintenance.
