STARS - Scoring Traffic at Roadworks
Overview
Objectives:
The aim of the Scoring Traffic at Roadworks (STARs) project is to enable National Road Administrations maintenance contracting authorities across Europe to set appropriate and effective contractual limits for the impacts of road maintenance and construction works on traffic, and to enable consistent benchmarking of roadworks safety across Europe.
Differing traffic management practices, born of differing approaches to addressing safety, result in variation across the European Union. In order to understand these national differences this study aims to generate a common method and standard to assess contractor performance
Methodology:
The main elements of the study are:
- To use existing and new evidence and experience to construct three comparable outcome-based scoring scales for performance at roadworks. The scales will reflect road worker safety, road user safety and traffic performance.
- To calibrate the three scales to account for international variability using scheme specific data from across Europe with a focus on roadworks on the Trans-European Road Network.
- To develop a single, unified metric based on the premise that the three scales are interdependent, as shown in the above triangle figure. This scale will be developed from unbiased rating of sample schemes and the performance of various nations and will highlight specific traffic management techniques that score highly across the three scales.
- To produce a practical tool for use by procurement officers and contracting authorities in setting contractor targets
The proposed method for this study uses a mixture of information collection and theoretical models. By drawing upon the strengths of six EU research institutions the project will be able to deliver a practical evidence-led scoring method.
