Using an instrumented bicycle to explore the responses of cyclists to pavement characteristics and defects

Abstract

Cycling offers great advantages in terms of space consumption, health and environmental sustainability, but is plagued by a poor road safety record, which has yet to be properly addressed due to a lack of understanding of the behavioural traits and responses of cyclists that would enable the design of suitable interventions. The aim of this study is to offer some insight into cyclist behaviour by investigating its relationship with the road environment, and specifically with pavement features and defects, such as High Friction Surfacing, cracks and utility covers. Using an instrumented bicycle, quantitative measurements of speed, steering angle and roll angle in response to different pavement features were taken from cyclists riding along a pre-determined route in Southampton, UK. The data were analysed using multiple linear regression and the findings highlighted a number of significant positive and negative effects to be considered in the design and maintenance of cyclist facilities.
