Contractor Report 161 Accidents at mini roundabouts: frequencies and rates

Publication Year

1989

Document Status

Withdrawn

Abstract

Presents the results of a study of the characteristics of mini-roundabouts. The survey included all roundabouts with a central island diameter greater than 4m but which are designed to allow vehicles to run over them and therefore operate in the same way. Accident frequencies and rates were obtained for the former category only.
