Design of Temporary ITS at Larger Road Works in Denmark

The Danish Road Directorate (DRD) is establishing temporary intelligent transportation systems (ITS) at two major motorway projects in order to improve traffic safety and traffic flow. Using stationary road markings to negotiate traffic on a construction site can impede the progress of widening the motorway because it can restrict the free movement of road workers and transport of materials to and from the construction site. Additionally, it is a very detailed process that requires close inspection every time a change is made to a sign board. Conventional sign posts would have been very difficult to use at the two projects under consideration because the projects employ two different approaches in carriageway widening. In one of the projects, the carriageway widening will be done symmetrically, while the other location requires the utilization of asymmetrical widening. One feature that is common to both of these projects is that the road works shift from one location to another as the project proceeds and this means that the system design has to be flexible enough to allow for managing such issues as lane closures or limited lane usability. As a result of this, the ITS has inbuilt flexibility that allows for the lateral displacement of the lane control signs when the traffic lanes are shifted.
