Although the bicycle was the first personalised transport machine to be mass-produced, it had received little attention in road research for many decades prior to 1975, when this study was commissioned. This report summarises and reviews existing knowledge from an Irish aspect. At this time, it was believed that there were at least half a million bicycles in the Republic of Ireland, and many believed the usage would significantly increase if the major problem of safety arising from the speed differential between cyclists and motor vehicles were satisfactorily resolved.
