IRIS is a Vias institute project commissioned by the Conference of European Directors of Roads (CEDR)The main aim of the IRIS project (Incursion Reduction to Increase Safety in road work zones) is to improve the knowledge on traffic management at work zones in order to increase safety for road workers and road users. The project will present conclusions and recommendations to road authorities and share information about best-practices in temporary traffic management for short, medium and long term road works. This also includes procedures and guidance for road inspection and audit methods.

The project starts with an in-depth analysis of statistics on accidents in or nearby work zones using existing databases such as CARE and IGLAD. Moreover psychological mechanisms will be reviewed that can explain some patterns of road accidents nearby work zones. A review of recent literature and studies will enable to identify existing audit and inspection practices and their (estimated) impact on the safety of road works. Also other existing practices to prevent incursions into work zones will be summarised. Based on this information a guidance document on Temporary Traffic Management layouts will be prepared and recommendations for road safety audit and inspection procedures will be developed.

The project will be finished in 2019 and is managed by a consortium of three partners: Lund University (Sweden), Kuratorium für Verkehrssicherheit (Austria) and Vias institute.

Vias institute will contribute to all parts of the project, with particular responsibilities for the in-depth analysis and the dissemination of the results.
