Planning and Implementation of Automatic Vehicle Location Systems for PublicTransit

摘要

The current state-of-the-art AVL technologies, applications, and potentialbenefits are described in this report. Results from a survey conducted among 135 transit properties are summarized. The survey results show that smaller agencies are less likely to implement AVL since there are less incentives as congestion and crime problems are far less serious than in larger urbanized areas. Other survey results include the commonly used technologies, some of the planning practices, the implementation experiences, etc. Documents related to system specifications and bidding were obtained from a number of transit properties, and are summarized to provide information on some of the technical requirements of AVL systems.
