The influence of lateral position when measuring road surface characteristic data: introductory study

Download

In conjunction with development of rolling resistance models it has been brought up to date that the knowledge of the size of variation of road surface characteristics data across a road section is not well known.

In a rather limited VTI study it was shown that the MPD (Mean Profile Index) level varies with lateral position, especially on smaller roads which are often used as test sections in model development. Also other road surface data such as IRI (International Roughness Index) and megatexture vary. Another conclusion is that data used for model development should be collected. The study is a part of the MIRIAM project.
