Rail Transit Operations Analysis: Framework and Applications

This thesis investigates strategies to improve service quality performance on a rail rapid transit line. Using data sources now commonly available, such as databases in Automatic Transit Supervision systems, an approach is suggested that uses available data and continuing input from agency personnel. The approach aims to draw out local operational and institutional conditions affecting service ...

A DEVS library for rail operations simulation

Detailed yet computationally efficient simulation models are needed to support the design and operation of modern rail infrastructure systems. LIBROS-II is a model component library for microscopic rail operations simulation. Basic rail elements are modeled as atomic DEVS models which are further aggregated into more elaborate rail component models. The latter can in turn be used modularly for ...

Approximate dynamic programming for rail operations

Approximate dynamic programming offers a new modeling and algorithmic strategy for complex problems such as rail operations. Problems in rail operations are often modeled using classical math programming models defined over space-time networks. Even simplified models can be hard to solve, requiring the use of various heuristics. We show how to combine math programming and simulation in an ADP-f...

Real Time Simulation of Rail Dispatcher Operations

Cognitive task analyses (CTAs) have been conducted to better understand the thoughts and actions of modem railroad dispatchers. These have provided information necessary to any investigation of dispatching operations, especially the study of the impact of new communications technology on the dispatching environment. This project was conceived to provide an empirical test-bed for such technologi...
