My attempt at a pedestrian crossing for Scratton Road – a fail so far
November 28, 2012 2 Comments
Following on from a number of conversations with the residents of Scratton Road, and neighbouring streets, I am looking to have a pedestrian crossing installed in Scratton Road. I believe the road is busy, and that a crossing would make the road safer for families and the elderly.
Thus far I have been knocked back in my attempt. What follows are extracts from some correspondence I have had with the relevant council officer.
Unfortunately, the calculation of PV2 (pedestrian volume multiplied by vehicular volume squared) was made that gave a value of 0.17. For a pedestrian crossing to be justified for further investigation, the value of PV2 needs be over 1.0. Therefore, as the threshold was not met, the proposal was not progressed any further.
For your information the PV2 approach to assessing the justification of proposed pedestrian crossings was presented to the Traffic & Parking Working Party and Cabinet Committee in June 2012 and agreed.
I am therefore unable to take the proposal to introduce a pedestrian crossing in Scratton Road any further at the present time. However, we will continue to monitor the situation.
The speed surveys were carried out at three different times along Scratton Road, between September 2010 and October 2011. The highest average speed recorded was 25mph at around the middle part of the street, which is where you would expect the fastest speeds to be. The first two surveys recorded average speeds of between 19 mph and 21 mph.
When considering whether a proposed pedestrian crossing is justified, the main consideration is for pedestrian demand and potential conflict with vehicular traffic and this is what is measured by the PV2 calculation. Other factors, like speed and personal injury accidents are also a consideration, but regrettably, overall there is no justification for a pedestrian crossing in Scratton Road, based on the data that has been measured. The table below summarises the speed survey data for your information.
Date road location total vehicles % exceeding limit
|Date erected||Date removed||road||location||Total no vehicles||% exceeding limit||Avg speed

Please note that equipment sited near No.15, is approximately 200m east of the roundabout (the road is approximately 400m in length).
