Limits and Restrictions
The analysis which Agilysis created looked at one sample area, and had data from more than 10,000 vehicle movements. The details of their report has shown that the information was collected automatically using a combination of location technology and information generated via new cars which have data-collection tools provided by the manufacturers. A close examination of the changes in speed showed that once the scheme was introduced - after the first week - the average speed of motorists in the sample area had dropped by 3.1mph on average. However, this fell to 2.3mph after a month of the new rules being in place.
An Expert Opinion
Richard Owen was the author of the report, and the CEO of Agilysis. He had the following to say about the report: “The evidence on this smaller sample of roads indicates there is no room for complacency. Although the majority of motorists are sticking to the limit, there will be concerns about the minority who haven’t adjusted their speed choices enough. Understanding which roads are seeing lower levels of compliance could be critical in targeting education and enforcement to achieve better compliance. To add some context, the industry usually considers the top 15% – referred to as the 85th percentile – as an indication of where to look at speed management, whether that’s engineering like speed bumps or gates or some kind of enforcement. However, it seems no one can yet enforce the 20mph limits anywhere in the UK because the equipment needs to go through a type of approval process and the government system is so backlogged and has been for about a decade, things are taking an age to make it all the way through. I was at a conference this week where understandably 20mph was raised a few times and they talked about an updated report which reviewed similar schemes in Scotland, Ireland and England and the effect it’s had on casualties.”
