The Walking Profiler (WP) is a precise measurement instrument for collecting and presenting continuous paved surface information. The WP meets World Bank Class 1 Profilometry requirements and produces outputs including profile, grade, distance and International Roughness Index (IRI).

The WP samples the pavement surface at a walking pace. As the built-in data acquisition module collects and stores the data, the results are displayed in real time for simple and quick data analysis.
