| The
book contains sound advice on site selection,
layout details, with a special section on
T-junctions and cross-roads, a simple capacity
test and much guidance on features of design that
contribute to safety. |
Safety
is an integral theme throughout. |
| This
is still the only comprehensive design guide for
mini-roundabouts that has been published and it
has proved popular with over 800 copies sold in
the UK and abroad since publication in October
1996, with many repeat orders . |
In
view of the previous lack of design information, Mini-roundabouts
- Getting them right! 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. |

The
Mini-roundabout Seminar
Comprehensive
seminar/workshops IN-HOUSE on all aspects of the
design, use and installation of mini-roundabouts
developed over the last several years, which can
be tailored to meet your needs.
Optional
assessment of your problem sites can be appended
as an additional half day to the seminar.
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.

| 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).
H-humps Although
there are some of these (Hounslow and Belfast),
they are far too few to test properly. Their
potential may be enormous.
