FOREWORD

The modern concept of a mini-roundabout was introduced in the UK in the early 1970s as a means to improve capacity and reduce delays at existing junctions where there was limited scope to introduce other forms of control. Since that time, most local authorities have developed their use to address other issues such as casualty reduction and as a speed-reducing feature within traffic-calmed areas. There are about 5,000 mini-roundabouts around the country and a great deal of experience has been gained in their application. The purpose of this document is to pull together this wealth of experience so that it can be shared with all those involved in the various aspects of highway management. It is important to note that this document is not intended as a design standard, but rather to provide guidance concerning appropriate locations and situations where mini-roundabouts should be considered. We would like to thank all those involved in the production of this document for their commitment and hard work. In particular we wish to thank Faber Maunsell, members of the CSS, the Steering Group and the many authorities and organisations that have provided information and examples of good practice.
