Toward the Use of AVL Buses as Probes for Regular Vehicle Traffic Conditions Estimation: A Literature Review

Large spatial and temporal coverage and regular frequency (headway) make transit buses equipped with automatic vehicle location (AVL) system an attractive alternative data source for an urban signalized street advanced traveler information system (ATIS). Although research of using AVL buses as probes can be traced to more than a decade ago, the real-life applications are scant. This paper reviews five relevant studies since 1990’s. The study objective, data, modeling techniques, application types and findings about the utilization of AVL information are summarized and compared. It is identified that the major obstacles in utilizing bus probes are the many unknowns of bus–car dynamics in an urban traffic stream, the uncertainties in bus operations, the lack of knowledge of traffic phenomena on urban streets and the technical challenge in handling of AVL data. Thoughts of future research needs are given at the end of the paper.
