Tensions at the heart of the nature of cycling remain: on the one hand cycling is frequently viewed as being a risky activity, while on the other hand it is seen as being a way of allowing populations to live healthier lives. Reviewing this dichotomy, the authors in this book consider the ways that cycling is planned and promoted. This is done partly in relation to these issues of risk and health, but also from the broader perspective of behavioural response to the changing nature of cycling. A section on methodologies is also included which outlines the current state-of-the art and points a way to future research.
