Stanpit Traffic calming
In preparation for the Community Service meeting next Wednesday I have now obtained the relevant statistics from the traffic survey conducted in July and August. Eleven data points were constructed comprising hydraulic tubes across the road which measured traffic volume in passes Northbound and Southbound and the 85% percentile speed of traffic as it passes through the system. On average traffic was passing at 28.15 mph within the 30mph limit and indicated a low percentage of vehicles exceeding 30mph and an even lower percentage exceeding 40mph (this represents a massive fall in the number of vehicles exeeding the speed limit). Higher traffic volumes occur from Purewell Cross to where the traffic calming scheme is located and this applies to both directions, this is clearly due to traffic feeding into and from the residential areas. My interest was to establish whether or not the scheme had made a difference and comparing the stats with those taken in 2007 (prior to the calming scheme) show that that speeds have fallen by as much as 20% from Queens Road down to the Guides hut. This is a good result especially as we now have in hand further measures to make the current scheme more stringent. What has not appeared to have altered is the volume of traffic using the system. This is a difficult thing to properly quantify as the data was obtained in Oct 2007 and would not have included so much holiday traffic. This will be subject of a full debate on Wednesday and will, I am sure drive our attitudes to this Borough wide problem of speeding traffic.
