Åtgärder för att minska hastighet förbi vägarbetsplatser: utvärdering baserad på tre fältförsök

Mats Wiklund

A state-of-the-art literature survey concerning the improvement of road-work safety has previously been carried out. A list of potential new measures was produced and several of these were prioritized, for further investigation, by the Swedish Road Administration. The investigations of three of these prioritized measures are documented in this report: - Intelligent congestion warning system, - Dynamic message sign (DMS), - Optical speed bars. The measures were tested in field at real road-works and all three measures, each in their own way, have the potential to increase traffic safety at road-work zones. In the report, questions that remain to be answered are highlighted and some alternative designs of the measures are proposed.
