Travel Times in Virtual DMS

A “Virtual DMS” method has been created for presenting travel time information to callers of the North Carolina 511 traveler information telephone service (NC 511). When travel time information is presented to drivers on Dynamic Message Signs (DMS), the travel times reported are measured from the physical DMS to a downstream location, such as a cross street or interchange. As such, the traveler’s location and direction of travel are fixed. This presentation format is much different than traditional 511 travel time dissemination where the caller’s location and direction of travel is not only variable but the caller could be calling from, or could be interested in, any roadway. North Carolina combined the best of both DMS and traditional 511 travel time presentation, providing callers their travel times to downstream exits based on their current location and travel direction; termed “Virtual DMS”.
