Why is this site necessary?

Mini-roundabouts are being used where they should not be:

Mini-roundabouts are not a good traffic calming tool unless justified by the turning movements at the intersection concerned. If traffic calming is the main reason for a scheme think carefully.

Mini-roundabouts are being used where they should but are poorly designed.

• Poor signing

• Lack of deflection for crossing streams

• Little done to change layout on approaches

• Lack of respect for central island - too low or too easy to overrun, often not large enough.

See the remainder of this site for information on all the design details.

Mini-roundabouts are not being used where they should be:

• Busy junctions

• Turning traffic

• Queues, congestion

• Accidents
  Why?

• Lack of confidence in potential

• Alleged need for "better" pedestrian facilities.

• Fear of innovation e.g. central island over 4m diameter at crossroads.

Comprehensive seminar/workshops IN-HOUSE on all aspects of the design, use and installation of mini-roundabouts developed over several years, which can be tailored to meet your needs.

Team up with the Traffic Calming seminar (started in 2000)
and have a double bill!

The seminars have been very popular.
For more information see the
Seminar details page.

The Workshop aspect is that we can look at your problem sites as part of the day. This has proved to be one of the most interesting parts of the day when real issues get a thorough airing at real sites.

ROAD SAFETY IN NIGERIA

This presentation was given by me at the 20th Anniversary International Road Safety Conference of the Federal Road Safety Commission of Nigeria. It was a great privilege to have been invited to participate in this event. Saving lives in Africa...

There seems to be a serious lack of confidence in the mini-roundabout. Cayman Islands for example took over three years to implement a scheme that I knew would work well and could have been installed in a day! But this happens. This work is designed to encourage you to introduce these schemes where they will work best. Correctly done they will reduce numbers and severity of accidents and cut congestion.

Here you will find lots of information about when & where to use a mini-roundabout, how to improve the safety of an existing mini-roundabout and lots more about making the geometric layout for your whole urban area more pedestrian and cycle friendly without resorting to traffic signals.

The main issue with the new TD is that it failed to put engineering before law. The UK TSRGD defines mini-roundabouts with central islands not larger than 4m. I have been pressing for this to be changed for many years. This was the golden opportunity to do this but it was not taken.

Most of my sales are made by email - I am happy to send the book anywhere with an invoice.

The Leeds seminar on Thursday 15th February 07 used up the last of the original books.

This is still the only comprehensive design guide for mini-roundabouts that has been published, fully updated from Mini-roundabouts - getting them right! which itself has proved popular with 998 copies sold in the UK and abroad since publication in October 1996, with many repeat orders.

Mini-roundabouts - A Definitive Guide is essential reading for all engineers, designers and safety auditors practising in this field, and important too for planners and town centre designers. Highway design engineers will also gain much useful information concerning layouts and profiles.

I have set up this site specifically to advance the use of larger mini-roundabouts in the UK

Crossroads probably in urban areas and therefore subject to a 30mph speed limit, where there is either an existing mini-roundabout which could be enlarged or where a new mini-roundabout could be installed which would be over 4m diameter to test the effectiveness of using the larger size. The current official maximum size of 4m (UK) has reduced the use of mini-roundabouts at crossroads - some authorities will no longer install them.

In Germany these larger mini-roundabouts have an excellent safety record (better than compact normal roundabouts).
