Analysis of Rail Transit Operations with Rail Track Circuit Occupancy Data

Transit agencies have made a significant investment in centralized operations control systems (OCS) for their rail transit lines. In addition to their important role in safety and management of transit operations, OCSs collect and store volumes of data related to the movement of trains through the system. Based on the activation/deactivation times recorded for each block by OCS, useful information, such as headway and travel time distributions, schedule adherence, and even vehicle trajectories can be extracted. This information can then be used for service monitoring, design of more effective service maintenance strategies, and operations planning and schedule design. The paper demonstrates the use of the data through a case study of MBTA’s Red Line.
