Increasing Railway Efficiency and Capacity Through Improved Operations, Control and Planning
"In chapter 5, I develop a new decision support framework to help capacity planners determine how to optimize the allocation of capital investment for capacity expansion projects. This framework has three stand-alone tools: (1) an ""Alternatives Generator"" that enumerates possible expansion …

Improving transit service connectivity : the application of operations planning and operations control strategies
… variability in vehicle arrival times. On the control side, the practice currently adopted at CTA is to hold a "ready" vehicle at a transfer stop if the connecting vehicle has already arrived and this is likely to be an effective as well as easy-to-implement control policy.

Diagnosis and assessment of operations control interventions : framework and applications to a high frequency metro line
Service control, the task of implementing the timetable in daily operations on a metro line, plays a key role in service delivery, as it determines the quality of the service as provided to passengers. This thesis proposes a framework for the study of rail service control which builds on the …

A Real-time Management of Distribution Voltage Fluctuations due to High Solar Photovoltaic (PV) Penetrations
… for the grid operator. Traditional voltage control devices like switched capacitor banks or line voltage regulators can alleviate slow-moving fluctuations, but these devices need to operate more frequently than usual when PV generation fluctuates due to fast cloud movements. Such frequent …

Running time variability and resource allocation : a data-driven analysis of high-frequency bus operations
… which must be dealt with through real-time operations control. An aggregation method is developed to measure the non-systematic variability of arbitrary time periods. Visual analysis tools are developed to illustrate running time variability by time of day at the direction and segment …
