A Director of Jenoptik UK, formerly Vysionics, has admitted that it's frustrating for the business that speed cameras continue to be criticised when they do a proven job of improving road safety.Geoff Collins was talking to Smart Highways editor Paul Hutton about a paper he's given at the ITS European Congress in Glasgow about the A9 project in Scotland which features the UK's longest ANPR-monitored average speed corridor.In the interview he explains how there has been a significant reduction in the numbers of killed and seriously injured people on the road since the system was introduced around a year and a half ago.  But despite this there are some people who still try to find data referring to very small sections of the overall road where numbers may not have changed, and try to spin this to suggest the system is not working.In the interview, Collins also talks about the rebrand from Vysionics to Jenoptik and confirms that it will not have an operational effect on day-to-day UK work.You can hear this fascinating interview here:[audio mp3="http://smarthighways.net/wp-content/uploads/2016/06/geoff-collins.mp3"][/audio]Picture, Geoff Collins discussing ANPR average speed camera technology on the Jenoptik stand
