A Systems Approach to the Management of Skid Resistance Deficiencies on a Road Network

This paper describes the development and use of a new tool that provides an improved approach to the assessment and treatment of sites with insufficient skid resistance in New Zealand. This work has been carried out initially in the Performance Specified Maintenance Contract (PSMC) environment where the contractor must take full accountability for meeting a range of pavement parameters, including skid resistance. Typically, the inspection of skid deficient sites is undertaken by experienced road engineers, who decide what type of action is needed to address skid resistance deficiencies on the network. However, that approach, based on site inspections alone, can lead to significant oversights and errors in the assignment of treatments to skid deficient sites. To address this problem, a new approach was developed which synthesizes historic skid resistance trends, accident data and pre-scheduled works. Using this integrated approach in conjunction with site inspections, the pavements engineer can make a more informed and holistic assessment of the site deterioration trends, likelihood of accidents and cost of intervention. The approach outlined in this paper has been implemented on several road networks with significant gains in inspection process efficiency and consistency of assigned interventions. The paper outlines the background to the methodology, putting specific emphasis on the PSMC context and the need for innovation. The key motivators behind the system are described and a detailed description of the methodology, with example outputs, is presented.
