Samenvatting
Drivers' revealed responses to active Variable Message Sign (VMS) information in North London was surveyed during Autumn 1998 as part of the demonstration stage of the CLEOPATRA project. The information displayed related to delays caused due to road works downstream of the VMS location on the A1 Archway Road. The information was relevant to only this one sign in the London system. A survey of drivers' revealed behaviour in response to the message was conducted during off-peak conditions. The findings from this survey are reported in terms of drivers' use of the information, their revealed (reported) behaviour and their opinions of the VMS information, both specifically in relation to the sign location, and in general.
