Nothing very noteworthy here. There are a lot of vehicles slowing to turn into Jessop Road or Freemans Lane – hence the modal speed of 17mph and the correspondingly reduced averages. We have extracted this data, cleared the memory and then turned the device round to face towards the old railway bridge so that we can compare the statistics for the Northbound traffic.
The data set runs from midnight on Sunday 10th to midnight on Saturday 16th – an exact 7 day period.
Colehill Parish Council jointly own the Speed Indicator Device with Holt Parish Council. It is managed in conjunction with a team from Dorset County Council, however the deployment and data collection is by Parish Council volunteers. It can only be deployed on purpose-erected poles at several sites across the two parishes – as agreed with County Highways.
