Towards 3-minutes : application of holding and crew interventions to improve service regularity on a high frequency rail transit line

Transit service regularity is an important factor in achieving reliable high frequency operations. This thesis explores aspects of headway and dwell time regularity and their impact on service provision on the MBTA Red Line, with specific reference to the agency's objective of operating a future 3-minute trunk headway, and to issues of service irregularity faced today. Current operating practices are examined through analysis of historical train tracking and passenger fare card data. Headway regularity is explored in the areas of initial headway regularity, stability of line headways, and passenger impacts. A metric of effective utilization is proposed which quantifies the effect of headway irregularity on passenger capacity on an individual train basis. Dwell times are explored through a statistical approach without passenger regard, and through a regression approach with passenger regard, both applied to automated data.
