In this edition of Thinking Aloud, Paul Hutton looks forward to the IMSA conference in Arizona by talking to Aegis ITS, part of the Econolite Group. We also feature the Innovacarretera event in Spain, where Paul speaks to two demonstrators from CIDAUT - monitoring system Amac and Cidro Crossafe - plus tyre recycling system GomaVial and crash barrier manufacturer Hiasa. And Thinking Highways Editor Kevin Borras looks through the new North American issue of the magazine. Remember you can sponsor Thinking Aloud at one of the many events coming up later this year - listen to the show for more details or email [email protected].
