Measuring of gravel road evenness with acceleration sensor technology

The Finnish public road network is 78 000 km of which 35% are gravel roads. They generally belong to the low volume road network, which provide standard level services. The objective of the project was to develop a method to measure the evenness of gravel roads automatically. The method uses a vehicle equipped with a measuring instrument and data collection unit with data transfer connection. The measuring instrument affixed to the car includes a vertical acceleration sensor and a terminal unit with a data collection module. The measuring method for gravel road evenness was developed by defining an interface between the software application and the measurement unit. The measurement of road evenness recorded by acceleration sensors was researched with the vertical accelerations made by two cars. The impact of tyre pressure was also studied with the car's vibration test equipment. The research concluded that gravel road vertical evenness can be measured automatically. The disadvantage of the acceleration sensor method is that it only gives information from the driving line. The advantage is that a large amount of information can be collected in real-time. The method can also be applied to other purposes such as measuring the road surface roughness.
