An Investigation of Operational Procedures for Highway Advisory Radio System by Brain Smith et al.
Motorists continue to rely more on commercial radio traffic reports.
A key objective of ITS is to provide travelers with accurate, real-time information, helping them make better decisions as to when to travel, what mode to use, and what route to take. Developing this capability is important, and VDOT's Intelligent Vehicle-Highway System Strategic Plan identifies traveler information system as a priority area. However, the AM radio is an interface currently available in nearly all automobiles. VDOT is currently using HAR to advise motorists of traffic conditions in the Hampton Roads tunnels, to manage traffic during construction on Interstate 66 in North Virginia, to assist in incident management and in work zones in other areas of the state. HAR is an opportunity and a significant challenge.
