Measuring, Managing, and Reducing Pavement Macrotexture and Roughness to Improve Cyclists' Safety and Ride Quality

Surface texture and roughness of bikeways directly affect the bicyclists' ride quality (Li et al., 2013). Texture and/or roughness requirements for bike paths and shoulders need to be established to improve cyclists' comfort. Aggregate embedment depth and macrotexture for chip seals need to be controlled during construction to achieve smoother pavement surfaces that are more suitable for bicycles. Effective post-construction treatments to improve ride quality should also be determined. Improved bikeway surfaces and ride quality can potentially increase bicycle use for commuting and recreational purposes in the Pacific Northwest. Reduced texture and roughness on bikeways can also reduce bicycle damage and increase cyclists' safety. This research would have three objectives: (1) determine the impact of pavement-related factors on cyclists' ride quality; (2) identify routes with lower ride quality; (3) provide suggestions and guidelines to improve user comfort.
