ASPEN uses a smartphone mounted in a vehicle (car or van, electric scooter) to examine the level of vibrations using an accelerometer and gyroscope. While driving, the smartphone shakes like an aspen leaf, thus collecting data on a given stretch of road, which it then translates into indicators that determine road surface evenness and driving comfort. In ASPEN, we used, among other things, machine learning methods and the IRI – the International Roughness Index.
ASPEN is not an alternative to classic pavement condition survey methods. It does not calculate some of the complex indicators present in official procedures such as ZEB. Thanks to this, measurement data is collected and processed much faster, and the versatility of the system allows it to be used not only on roads but also on pedestrian and bicycle routes.
