Project summary
This project analysed road surface skid resistance and road traffic collision data for selected local authorities, to develop a model of the relationship between skid resistance and collision risk for a typical ‘city’ road network. The model provides road engineers an evidence-led approach to prioritise maintenance funding.
Phase two of the LASR Approach has now been approved, with 13 Local Authorities tasked with implementing this new approach in parallel with their existing approach to managing skid resistance. Where they find sites that they consider to justify treatment, the LASR Approach team will work with them to identify pairs of sites with similar characteristics, of which one will be treated and the other will form an untreated control. Following treatment, the LASR Approach team will monitor the collisions occurring at treatment and control sections and assess the benefit from treatment.
