An interview with Kate Carpenter, technical director at Jacobs, is presented in which she discusses the difficulties facing designers of traffic calming schemes. A key challenge is that traffic-calming schemes are not governed by just one set of regulations or standards. Some elements have no design standards, but instead have advisory notes and case studies. She believes that one reason why so many traffic-calming schemes are non-compliant is that designers are struggling to keep up with the multitude of guidance and regulations. The Institution of Highways and Transportation and Country Surveyors' Society published a 'Traffic Calming Techniques' book to clarify the design process. A series of non-standard signs and markings from traffic calming schemes in the UK are discussed. These relate to mini roundabout give way signs, mini roundabouts, chicanes and road humps. New approaches to the design of traffic calming schemes are discussed.
