Abstract:This paper presents the authors' understanding of a key tradeoff in ATIS investment planning: investment in expanding surveillance coverage to additional miles of roadway vs. improving the accuracy of the information provided on roadways already covered by ATIS. Building on previous work using the Heuristic On-Line Web-Linked Arrival Time Estimation (HOWLATE) evaluation methodology, they explored the relevant cost and benefit relationships to provide guidance to high level decision-makers implementing ATIS systems.
