Road quality is permanently monitored, allowing to follow-up road degradation over time and to detect anomalies (e.g. due to road works) or unusual rapid aging.
What sets Roads apart?
A number of technologies exist for measuring road surface state; the table below summarizes their properties:
|Laser scanning||High||Low one-time measurements, small number of roads||Very high dedicated hardware & expert personnel|
|CPX trailer||High||Low one-time measurements, small number of roads||Very high dedicated hardware & expert personnel|
|Visual inspection||High||Medium one-time measurements||High dedicated expert personnel|
|Camera-based||Medium only potholes and cracks||Medium one-time measurements||High dedicated expert personnel|
|Smartphone-based||Low only large potholes||High all roads, permanent monitoring||Low|
|Roads||High||High all roads, permanent monitoring||Low|
Roads uses a combination of noise and vibration, measured onboard ordinary vehicles, and provides the best of both worlds: high accuracy (calibrated against laser scanning and CPX measurement data), high coverage in space and time, and all that at a very affordable price. Furthermore, Roads has the following major advantages as compared to the above technologies:
