On-Time Reliability Impacts of ATIS. Volume III. Implications for ATIS Investment Strategies.

摘要

The effect of ATIS accuracy and extent of ATIS roadway instrumentation on the on-time reliability benefits to routine users of ATIS are evaluated through the application of Heuristic On-line Web-linked Arrival Time Estimation (HOWLATE) methodology. The HOWLATE methodology employs archived estimates of roadway travel times to recreate hypothetical, retrospective paired driving trials between travelers with and without ATIS. Previous research using this technique demonstrated that travelers who receive notification of current congestion prior to departure can realize substantial time management benefits from improved on-time reliability and trip predictability, and that these savings can be converted to a dollar-valued benefit. In this report, we expand the repertoire of applications of HOWLATE to investigate the impacts of ATIS accuracy and geographic coverage levels on the value of ATIS service, and how to best conduct ATIS evaluations using small data sets. We then examine the implications of these findings on the development of cost-effective ATIS deployment strategies.
