Roadworks warning is a safety-related Cooperative Intelligent Transport System (C-ITS) service that mainly aims to reduce the number of accidents caused by roadworks. Based on efficiency and
roadworks warnings contribute to the elimination of non-recurrent traffic jams.
Accidents often occur in connection to roadworks because road users do not anticipate properly or react too late or do not pay full attention to the traffic while changed situations - e.g. due to closed lanes because of short-term roadworks or changed road layouts. Therefore, it is important that the driver receives a warning timely to adapt his driving behaviour.
Different communication technologies will be implemented for the execution of this service RWW: An ITS Roadside Station (IRS) sends information to the ITS Vehicle Station (IVS) via ETSI G5. Another communication channel is Digital Audio Broadcast (DAB) to transmit the information to the navigation systems in the vehicles.
