A combination of technologies is leading to major congestion and cost reductions during roadworks on the UK's motorway network. Innovative construction programme scheduling technology and the deployment of moveable barriers has achieved substantial savings of money and time on UK motorway roadworks managed by the Highways Agency (HA). This combination has set the scene for a new generation of road usage analysis tools. The HA's objective was to reduce the congestion caused by lane closures during roadworks, while also enabling the work to finish as quickly as possible. To do this the technology is providing greater accuracy in the prediction of traffic flows and in matching current demand to capacity in a range of scenarios.
