Traffic data from SAM2 devices
A SAM2 is a vehicle activated sign that displays and records the speed of an approaching vehicle.
The Parish Council own two SAM2's. These are mobile units and are moved around the village on a regular basis.
SAM2 locations
For each location the Parish Council needs a licence from Norfolk County Council Highways department to mount a SAM2. These are the locations that the Parish council currently has licences for.

60mph recorded 11.12.24 at 22:40
Vehicles exceeding 30mph:
Approximately 37% of vehicles (depending on day of the week).
SAM 2A Comments:
All SAM 2A traffic data for December is very much the same as was recorded during the previous month. I have re-synchronised the radar clock against real time for this SAM. It appears to be working correctly now.

November 2024 data
Hi All,
Here is the SAM data for the period 31.10.24 to 01.12.24
The following is a summary.
SAM 2A Serial Number HR-BT-10565 (original SAM)
Location:
On Salhouse Road (B1140) adjacent to wherry gardens bus stop facing traffic coming from Salhouse.

Vehicles exceeding 30mph:
Approximately 36 to 42% of vehicles (depending on day of the week).
SAM 2A Comments:
There has been an issue with the radar clock being out of sync with live time. This has caused some errors with accurate timings of events, such as the timing of peak traffic movements. I will investigate the cause of this. Although timings are inaccurate, actual traffic volumes are broadly true. Data for November shows a decrease in volume of traffic coming from Salhouse by about 100 vehicles per day. Data for vehicles travelling in excess of 30 mph was broadly the same as last month.

The monitor was turned around '180 degrees' to collect data for the traffic going in opposite direction (ie towards Salhouse) during May. Prior to May it had been recording data for traffic coming into Wroxham.
The volume of traffic travelling to Salhouse (when compared with traffic travelling towards Wroxham) was slightly lower (by about 150 vehicles per day). However regarding vehicles exceeding the 30mph limit, there was a slightly higher amount. The difference being about 4% more. The monitor will remain in this position for June / July to give a more accurate picture of vehicle movements travelling towards Salhouse over a longer period. _______________________________________________________________________________

Period:

Vehicles exceeding 30mph: Approximately 41 to 45% of vehicles
SAM 2A Comments:
Volume of vehicles shows a slight increase on the February data by about 100 vehicles per day. Vehicles travelling in excess of 30mph is almost identical to February data, at 41 to 45%. This Salhouse Road continues to be the main location in Wroxham for volumes exceeding 30 mph.

Period:

Data:
Total vehicles:
200,616 (an average of approx 7,716 vehicles per day). [note that data between 26th and 30th March was not recorded due to flat battery so daily figure adjusted accordingly from 6445 to 7716].
Max speed recorded:
85 mph recorded 01.03.24 @ 08:20
Vehicles exceeding 30 mph:
Approximately 14 to 20% of vehicles
SAM 2B (New) Comments:
Daily traffic volumes for March were higher than the previous month by about 900 vehicles per day. Vehicles exceeding 30mph were about the same as previous month. There was one significant speed recorded at 85mph, which is quite extreme for morning rush hour. It is possible this could have been a malfunction (for no other reason than travelling at 85 mph at 08:20 would be extremely dangerous at this location), however 2 vehicles were recorded at 70 mph. 5 at 65 mph and 25 at 60mph. Although this represents a very small proportion of the 200,000 vehicle movements, travelling at double the speed limit is not safe.
General Comments:
The monitors will remain in the same positions for April. (SAM 2A on Salhouse Road facing traffic coming into Wroxham and SAM 2B on lamppost 30 Norwich Road facing traffic coming into Wroxham.

SAM 2A Comments:
Monitor moved to Salhouse Road (facing traffic coming into wroxham) on 01.02.24. Comparing data with data recorded at this position (during February 2022) volume shows a decline by about 440 vehicles per day. Vehicles travelling in excess of 30mph also declined compared to February 2022 (down by about 15%). This is possibly due to the 30mph zone being expanded further towards Salhouse. However 41 to 47% s still a high proportion of traffic volume that exceed 30mph.
