This Thinking Aloud comes from the Traffex show at the NEC near Birmingham, United Kingdom.

It's brought to you by AGD Systems, Flir ITS (formerly Traficon) and Swarco.

Paul Hutton brings you a flavour of the event and hear from organiser Bill Butler, RingGo's Harry Clarke and Sukhdev Bhogal from Flir ITS.

There's also a flavour of the documentary about enforcement which is featured on the Thinking Highways website to go with the new issue of Thinking Highways magazine, while Kevin Borras looks ahead to the launch of the new British-based magazine Smart Highways.
