MVAS & SIDS case study


  • Project name: Speed Indication Device (SID) Installation
  • Client: Staffordshire County Council & Staffordshire Casualty Reduction Partnership (SCRP)
  • Area: Staffordshire
  • Value: £30,000
  • Date: 2011

The Staffordshire Casualty Reduction Partnership (SCRP) is an organisation that works with several agencies, including Staffordshire County Council, Staffordshire Police and Stoke-on-Trent City Council, with the aim of reducing road traffic accidents by encouraging drivers to lower their speed.


The organisation was looking for ways to change the behaviour of road users, without incurring the substantial cost of installing fixed speed cameras in multiple locations. Key criteria were portability, programmability, and cost effectiveness.


JPCS worked collaboratively with the SCRP and members of the local community to understand their requirements and develop options to identify a solution for the speeding issue, whilst providing flexibility and cost-effectiveness. The result was subsequent investment in 30 speed indication devices (SIDs) on hinged posts. SIDs are effective at reducing the proportion of vehicles exceeding the speed limit.

Groundscrew installation

The innovative Groundscrew® foundation enabled the fleet of SIDs to be moved periodically between a large number of pre-determined locations. Using Groundscrew® meant that there was no requirement for permanent fixings and re-siting the SIDs was quick and low-risk. As a result, JPCS was able to minimise the disruption experienced by the local community and the impact on the environment.


Groundscrew fittingJPCS installed 197 Groundscrew® foundations at key sites in the Staffordshire area. Once the foundations were in place, the SIDs were installed at their initial locations.

JPCS then took over the management of the scheme: every three weeks the data is downloaded from the devices, which are then moved to the next location, as specified by the SCRP.

Key Benefits

  • Minimised disruption through installation and re-siting – the SIDs can be installed or moved very quickly in response to local demand
  • A cost-effective, sustainable and flexible solution to meet the needs of local communities
  • One point of contact, including accurate speeding data collection in a given area so that the SCRP can work with the Council to identify other speed reduction methods.
