General highway condition of carriageways and footways within in the borough are assessed over a 2 year period.

Our unclassified roads represent the largest proportion of the network and yet the lowest levels of traffic movement.

Stockport uses GAIST to monitor the condition of the network. GAIST monitors surface condition using a combination of high-definition cameras. They capture images along the road creating a "video-like quality" to show asset condition. This imagery helps identify changes, monitor degradation, and provide real-time intelligence for road maintenance and infrastructure management.

A number of parameters measured in these surveys are used to produce a road condition indicator which is categorised into 5 condition categories. For compliance with the data metrics of Government reporting this can then be reported, when necessary, into 3 condition categories:

  • green – no further investigation or treatment required

  • amber – maintenance may be required soon

  • red – should be considered for maintenance

From 2026 to 2027 a new methodology will be used based on the BSI PAS2161 standard. Local Highway Authorities will be required to use a supplier that has been accredited against PAS2161. This new standard will categorise roads in a way that will help government gain a more detailed understanding of road condition in England. GAIST’s system is ready to meet the requirements outlined above.
