• Abstract:
  A growing demand for passenger and freight transportation, combined with limited capital to expand ; the United States (U.S.) rail infrastructure, are creating pressure for a more efficient use of the current ; line capacity. This is further exacerbated by the fact that most passenger rail services operate on ; corridors that are shared with freight traffic. Tools and methodologies for capacity analysis are one ; approach to investigate the situation. As the U.S. continues to develop higher speed passenger services ; with similar characteristics to those in European shared-use lines, understanding how such analysis are ; done in both continents grows in relevance. A detailed investigation was done to understand how each ; continent approaches capacity analysis, and whether any benefits could be gained from crosspollination. ; It was found that there was no major divergence between approaches or criteria used for ; capacity. However, there are differences in the tools used in these two regions, as the tool designs ; follow the main operational philosophy of each region (timetable based in Europe vs. non-timetable ; based in the U.S.). ; Timetable management is one of the operational methodologies commonly applied in the highly ; structured European rail system to improve the capacity utilization while maintaining acceptable level ; of service (LOS) parameters. The potential benefits of using similar methodologies to benefit the less ; structured U.S. system were studied in this research. A Hybrid Simulation approach was developed as ; part of the research to investigate the use of timetable management features and to analyze the tradeoff ; between LOS parameters and capacity utilization in the U.S. In the method, the output from Rail ; Traffic Controller (RTC), a simulation tool commonly used in the U.S., was used as an input for ; timetable compression by RailSys (a simulation tool developed in Europe).
