Comfort evaluation of new bicycle paths with a laser profilometer: 15 years of experience in Belgium

Longitudinal evenness of a road or bicycle lane surface is important for users’ comfort. For roads, indicators for evenness, their relation to users’ comfort in cars or trucks, and acceptance levels for existing or newly constructed roads exist for decades. In Belgium, four indicators called “Evenness Coefficients” (EC) are in use. Considering the surface as a wave, each EC evaluates a different range of wavelengths. EC0.5, for the shortest wavelengths, was introduced in 2013 by the Flemish National Road Administration (Fl-NRA). In 2013/2014 two measurement devices dedicated to longitudinal ev... Mehr ...
