The selection of roads where planned highways works are required is based on a full detailed video survey of the entire road network completed each year.
Road surfaces are graded based on their condition, from 1 (as worst) to 5 (best). Condition survey outputs are imported into specialist asset management software that assists with the visualisation of raw condition data and supports the development of annual programmes and lifecycle planning.
Weighted priority factors are applied to the base condition data scores to prioritise treatment locations. Priorities and associated weightings include:
- proximity to hospitals or GP Surgeries
- proximity to schools
- proximity to leisure and health facilities
- bus routes and frequency
- Live Job data (pothole)
Feedback may also be sought from highways safety inspectors and consideration given to streets with large amounts of insurance claims.
Treatment location outputs provide a sound starting point for further review and engineering assessment. Some higher-ranking schemes are progressed, but others may be deferred to be managed by reactive means until a wider scheme can be economically justified (works are often triggered for only a small part of the whole road/street) or until other developer or regeneration led opportunities can be realised. In some cases, the data is not representative of the actual asset condition following engineering assessments and schemes are not taken forward or may be deferred to later years.
The process described above is in accordance with National Guidelines. Schemes are based on fundamentals of condition need, but the process ensures that available funding is targeted to get the biggest benefits whilst avoiding ‘worst first’ principles which would address condition but not the wider need.
Further surveys relating to the skid resistance are also undertaken, the results of which feed into the Surface Dressing Programme. These surveys are undertaken on the entire classified network (A,B, and C roads), and analysis based on national guidance, with particular emphasis on areas such as:
- junctions
- intersections
- crossings
Works detailed here do not have scheduled dates. Consultation letters will be delivered to residents on all streets affected prior to start of any works in your area.
