Abstract—As part of ITS initiatives worldwide, Advanced
Traveler Information Systems (ATIS) provide potential travel-
ers with information and images from roadway and roadside
technology. This information benefits the traveling public by
improving pre-travel routing and other trip planning capabil-
ities. As part of broader traffic management ITS strategies,
these systems improve overall safety by reducing the number of
congestion-related crashes and improve the efficiency of trans-
portation systems by increasing roadway capacity. However, the
development of an ATIS offers numerous challenges that are
unique to the individual region served. The cost of deployment
and operation is of critical importance, particularly for states
with smaller populations and transportation budgets. This
paper presents the design of the Oklahoma Pathfinder ATIS,
addressing the state’s constraints and exploiting the state’s
unique ITS deployment. It details the information capabilities,
deployment experiences, and traveler reception of the system.
