This project, as part of a wider work plan, aimed to determine whether drivers can respond adequately to emergency situations when they are extracting information from co-located signs. It also tested whether drivers are able to extract information from co-located signs and make required decisions (e.g. drive to the required destination, or change speed) after an encounter with an emergency situation. The study was designed in collaboration with researchers from ARRB Group; it utilised the CARRS-Q driving simulator to test three critical scenarios in emergency situations with the following sign configurations:
- conventional sequenced sign locations;
- co-location of variable message signs (VMS) and variable speed limits (VSL) and/or lane control signs (LCS); and
- triple co-location of direction signs, VMS and VSL/LCS.
