ABSTRACT
The vibration experienced by cyclist greatly influences the cycling comfort on urban asphalt pavement. However, the relationship between pavement’s surface characteristics and cycling vibration remains undiscovered. In this work, the cycling vibration on urban asphalt pavement was evaluated using a self-developed device, and the 3D digital data of pavement surface was captured via the 3D laser scanning technology. Furthermore, the macro-texture of pavement surface was described via 8 parameters, and the correlation between parameters and cycling vibration is analyzed. The results show that Arithmetical mean height and average peak spacing are two main factors influencing the cycling comfort. Results of this study should be interested by cyclists, bicycle manufacturers, transport planners and road authorities.
