We now have our second set of statistics from our speed sign, stating again for clarity, this is NOT a speed camera. It does not record any number plate details.  Also, for the avoidance of doubt, the LVCA does not have an objective of getting a 20mph speed limit on Langford, it simply wants to raise speed awareness on our estate.

This set of data is for vehicles traveling from the Pipits Croft roundabout towards Ravencroft and Kestrel junctions, so when exiting the estate.  The statics are for a four week period starting Monday 13^th November and ending Sunday 10^th December.  During this time some 58,462 vehicles passed the sign in one direction, which averages 2,000 per day, or 4,000 per day if you assume an equal number of vehicles in the opposite direction.

The chart below puts traffic in 5 mph buckets, so for example 28,220 vehicles passed the sign doing 25mph to 30mph.  A total of 13,167 vehicles travelled past the sign above the 30mph speed limit, which equates to 22.5% of all vehicles, compared with the 12% that  exceeded the speed limit when the sign was located near Shearwater and Avocet junctions.  For context, nationally 50% of drivers break the 30mph speed  limit, which was somewhat surprising to me.

(Clicking on any chart will make it larger and more easy to read on your device)

The chart below is complex, it shows that on average that vehicles are traveling below 30mph, however we do have a considerable number of vehicles traveling at 35,40, 45mph etc, with one vehicle hitting 60mph.

The chart below provides the daily volumes for a single week.

The final chart, shows the flow of traffic through the day, highlighting a considerable morning peak in traffic flow.

The primary objective of the speed sign is to encourage us all to drive at a safe speed on our roads on our estate.  We hope you find these insights useful.  The speed sign has now been positioned to monitor vehicles entering our estate from the Kestrel Way and Ravencroft direction.  In the New Year a new socket will be installed near the school, and enable us to provide statics on vehicles using this stretch of road.

In the meantime, from us all at the LVCA, have a Merry Christmas and a safe New Year.

Following on from the original set of data from our local speed sign, we thought it would be interesting to take a sample week in order to share some more insights.  Specifically for the 7 days starting Monday 16th October, the following charts show:

1. Volume of vehicles passing the sign per  day.
2. Average volume of vehicles passing the sign per hour of the day.
3. The range of speeds vehicles are passing the sign per hour of the day.

Please note, the sign records vehicles one direction only, so the true number of vehicles passing the sign is doubled if you assume the same number of vehicles traveling in the opposite direction. Clicking on any of the charts makes them bigger and easier to read.

On a week day, approx. 1,700 pass the sign. If you double that to take into account vehicles traveling in the opposite direction, that is 3,400 vehicles – a surprisingly busy stretch of road.

The above chart shows the high volumes of vehicles per hour during the morning and early evening periods.

This is a complex chart, it does show that on average vehicles are traveling below 30 miles per hour. However, during peak times each day we have a considerable number of vehicles traveling at 35, 40, 45 and even 50 miles per hour down this stretch of road. Let’s all play our part in keeping this busy road safe for all residents of our estate.
