concerns over speeding vehicles.
Data from the recent traffic speed survey carried out on Horsham Lane, Upchurch between Monday 22nd and Sunday 28th July (inclusive) is now available.
Survey equipment was placed in Horsham Lane near the Crosier Court junction where it recorded traffic speeds both East and Westbound, 24 hours a day for a full 7 days.
The raw data (available to download at the link here >> www.upchurchmatters.co.uk/traffic-speed-survey-on-horsham-lane.zip) is broken down into vehicle types and numbers by time of day.
Below is the Traffic Manager's explanation:
“Speed survey equipment was placed immediately west of the Crosier Court junction, as discussed. Traffic speeds were recorded 24 hours per day for a full seven days by means of pneumatic tube counters. One of the limitations of this type of equipment is that it can generate some anomalies, for example when two vehicles cross the tubes at the same time but in opposite directions. This can ‘confuse’ the equipment and record what appears to be an exceptionally high speed for a couple of vehicles. The number of instances of this is usually very low and, because average data is used, these anomalies do not distort the data. However, we need to flag this in case people interrogate the raw data and spot these high speeds.
The two measures that are used when looking at traffic speed are mean (average) speed and 85th percentile speed. The latter is the speed at which 85% of vehicles are travelling at or below.
The mean speeds recorded were 27.2 miles per hour (westbound, i.e. towards Rainham) and 25.9 mph (eastbound, i.e. towards the village centre).
The 85th percentile speeds recorded were 31.9 mph (westbound) and 31.0 mph (eastbound).
These speeds are what we would expect on a length of road where 30mph applies (speed limits should be set so that the mean speed of traffic is below the enforcement speed for that limit, which, for a 30mph limit would require a mean speed of 35 mph or less).”
The traffic speed survey was paid for through a grant made by Swale Ward Councillor, Alan Horton to Upchurch Parish Council from his Swale Borough Council Ward Members Grant allocation (last year) and was to help inform the current Parish Highways Improvement Plan Consultation which residents can still take part in until Tuesday 20th August 2019, details of which can be found at the link here >> http://bit.ly/2M0XwSv
