Village Radar Speed Sign
The village now has it's own Radar Speed Sign, managed by the Parish Council.
Funded by the generosity of one of our village residents, the Speed Indicator Device (SID) is located at one of a number of locations and directions along the main road of the village for three weeks at a time.
The SID is not an enforcement device and does not log data to be passed onto the police - although they can request the data in the event of an incident. Instead, The SID encourages and influences drivers to slow down to the speed limit. While there will always be drivers who in the absence of enforcement measures will still drive above 30mph through the village, the data shows that the device has a positive effect on behaviours.
The SID records an average of 4000 vehicles going along the main road per day (roughly 2000 each way), and while some of the maximum speeds are extreme (and worrying - the highest speed recorded so far has been 92mph), the overall figures are interesting. The SID is moved regularly to one of six locations agreed with Highways, as their evidence indicates that the efficacy of Speed Indicator Signs drops off over time in one location. For each location, the Parish Council is currently recording a baseline (without the sign flashing, for one week) to find out what the normal speeds are, followed by the device operating for two weeks. This allows us to gather data to decide which locations are best placed to get the best use of the device.
Location 1 Village Boundary West
This location is just within the village boundary on the Alresford Road. It is very close to the 30mph incoming border.
Without the sign running (fig.1), only around 44% of traffic is at or under the speed limit after entering the village. A further 28% are doing up to 35mph. Of concern is that higher speeds (above 35mph) account for 27% of traffic, which is significant.
the SID running at this location only records the speed as the vehicle passes it - it lights up outside the 30mph zone, but it does not log those speeds (fig.2). It clearly encourages more traffic to slow down earlier than the 30mph border, increasing those at 30mph or under to 65%, up to 35mph down to 18% and importantly reducing the higher speeds down to 16%.

Location 2 Sutton Manor Farm
Further into the village, round the bend and on the long straight towards the Ship.
It was expected that this would have a higher figure of speed compliance than Location 1 at the border, but the figures are very similar.
(Fig.3) Only around 47% this far into the village is within the speed limit, with a further 28% up to 35mph. The higher speeds taking up 25%.
With the SID operating (fig.4) the 30mph or under drivers increases to 66%, up to 35mph reduces to 20%, and the higher speeds reduce to 14%.

Location 3 Bus Stop West
Opposite the Ship, this location is very far into the village.
The data shows that by the time that traffic reaches the Ship, there is an overall slowing down (fig.5) - a significant increase in 30mph drivers at 64%, with a further 21% up to 35mph. 15% of drivers are still driving at higher speeds. This still, however shows that 35% are still driving above the speed limit even here.
With the SID operating (fig.6), 30mph increases to 77%, with 35mph down to 14%. Very high driving is now only around 9%, but this is still just under 1300 vehicles in the sample.

Location 4 Centre
After the bend of Ship Hill, this location is opposite Park view Cottages.
The baseline data has been collected, and this shows that without the SID in operation, the vast amount of traffic is keeping the speed limit (90%), with very little at higher speeds. This is Higher than at any other point on the circuit, and is influenced by the bend of Ship Hill as vehicles navigate down the road.
The SID at this point has a much smaller effect, because most of the traffic is at or under the speed limit. The number of vehicles (fig.8) within the speed limit only increases by around 2% and the higher figures are negligible.

Fig. 8: Location 4 with the SID operating. Data collected 11-17 Dec 2021
Location 5 Bus Stop Centre
Located at the Bus Stop in the centre of the main road.
This also shows a high number of compliant drivers (fig.9) with 75% on or under the speed limit, and high speeds (41mph+) only at 2%.
With the SID in use (fig.10), the traffic at or now under 30mph increases by 9%. and the 31-35mph number almost halves. The higher speeds also reduce, but overall the difference is less than towards the outer ends of the village.

Location 6 Bus Stop East
Located at the Bus Stop opposite the Old Plough.

Location 7: Cobbs Farm
Located around 20 metres in from the village border, this monitors the long straight incoming from the Ropley Roundabout.
This end of the village is a very different picture (fig.13): the amount of traffic that is within the speed limit is very low, even 20 metres in from the 30mph border - only 35%. those going at up to 35mph is 22%. The big change is also in the higher speeds accounting for 43% of traffic - worryingly with 10% at very high speeds (over 1600 vehicles in one week). If this traffic is slowing down, much of it will not go down to 30pmh until half of the village distance. Over 65% of traffic is breaking the speed limit.
With the SID operating (fig.14), the 30mph compliance goes up to 56%, the up to 35mph offenders 17%, and the higher speeds reduce to 27% - which is still significant compared to the other locations. To put this into context, the very high speeds with the SID in use are still around two and a half times that of other locations without the SID in use.

There is a long way to go to fully understand the data and the behaviour of drivers. For example, how the device works within the different locations, which location is most effective and what improvements can be made will become more apparent as data is taken from each location Campaign over the next year.
The use of the SLR only affects the side of the road that it is pointing at. For this side, the device has had a significant impact on driving behaviours:
The device has influencing/encouraging an approximate further 20% of drivers who naturally drive above the speed limit to slow down to within it.
In addition, the number of drivers who are still speeding against the SLR has more than halved across all of the speed ranges.
The area of concern is the Ropley entrance to the village, with the road acting as a straight runway
These improvements are only for one direction of traffic at a time. The traffic on the non-SLR side of the road is still the higher ratio.
