Abstract
This paper presents experimental studies from the road profile measurements by employing accelerometers and international roughness index - IRI assessment tools and practical guidelines with respect to measured acceleration data processing in terms of digital filter design and conversion of vertical acceleration data into displacement data. In addition, it shows comparative analysis of measurements with accelerometers and Rod & Level (Leica TS 06 Plus), and gives some recommendations how to process measured data.
Highlights
It is a well-known fact that roads are one of the most vital sectors of economy of any nations
The measured data of the road profile can be evaluated by using international roughness index - IRI [1] and ISO 8608 [2] standards and national or regional standards some of them are based on the International Standards
In many studies dedicated to the road profile measurements, vehicle-road interaction is used as a main approach
Summary
It is a well-known fact that roads are one of the most vital sectors of economy of any nations. One evaluates the power spectral density (PSD) of the longitudinal elevation of the road profile All of these approaches have some pros and cons with respect to each other in terms of precision, accuracy, efficiency, application purpose and cost. In many studies dedicated to the road profile measurements, vehicle-road interaction is used as a main approach These standardized methodologies, there are a few other techniques used in practice. Some recommendations how to process measured data by employing digital signal filters and comparative analysis of terrain measurement tools are underlined. In these studies, a vehicle-road interaction approach to measure experimentally and evaluate longitudinal unevenness and assess it via a quarter car model of the IRI in numerical simulations is used.
