Methods This study mainly used three types of data sets relating to bicycle collisions, use of bicycles and local neighbourhood characteristics in Hong Kong.
In particular, bicycle usage, measured as bicycle-kilometres travelled, was estimated from travel surveys following the activity-based approach.
Objective This paper examines the relationship between bicycle collisions and the amount of cycling at the local level.
Most previous research has focused on national and city comparisons, little is known about differences within a city (the mesoscale).
Does the fact that there are no cyclists injured on a road necessarily mean that the road is safe for cycling?
