Welcome to Penntraff Traffic Engineering solutions!

By far the greatest amount of work has been in the field of mini-roundabouts. The Consultancy takes a pride in a long ongoing research of what works and what doesn't. This is a matter that has gone astray in the UK and Penntraff warns against many of the errors that we continue to make here for clients overseas. In France the numbers of normal roundabouts are increasing all the time - around 1,000 are completed each year.
Penntraff provides advice to local authorities throughout the world including a whole day seminar/workshop on the design and use of mini-roundabouts and a second seminar on traffic calming.
The Consultancy published Mini-roundabouts - getting them right! in 1996 and this has now sold out although a new version will be available shortly. See:

But Penntraff also carries out specialist studies for development schemes, helping to secure the necessary planning permission although this can never be guaranteed.
Penntraff will also carry out local studies on behalf of any clients private or public. Just call or email.
