More Trains : More Trains A B C D Slide 6: Is it possible to have more Trains? Taking Shorter Times? A B C D CAPACITY : CAPACITY “The maximum rate of output for a process.” -Lee J. Krajewski & Larry P. Ritzman Track Capacity???? Track Capacity : Track Capacity The highest number of trains per day that can be moved over a subdivision under a specified schedule and operating plan while not exceeding a defined threshold Key Features of Article : Key Features of Article Measurement of theoretical, practical, used and available track capacity. Definition of parameters which affect capacity measure by dividing them into three categories: plant, traffic and operating Capacity equations that are used to determine capacity utilizations for various parameter values. Measures of Capacity : Measures of Capacity Theoretical Capacity Capacity(# of Trains/day) Practical Capacity Used Capacity Available Capacity Used Capacity Track Capacity : Track Capacity Parameters Affecting Capacity Plant Parameter Traffic Parameters Operating Parameters Plant Parameter : Plant Parameter Length of the Subdivision Meet Pass Planning Spacing (MPPPS) Meet Pass Planning Uniformity (MPPPU) Intermediate Signal Spacing Ratio (ISSR) Percent Double Track (% DT) Traffic Parameters : Traffic Parameters Traffic Peaking Factor ( TPF) Priority Probability ( PP) Speed Ratio (SR) Average Minimum Run Time (AMRT) Operating Parameters : Operating Parameters Track Outages (TO’s) Temporary Slow Orders (TSO’s) Train Stop Time (TST) Maximum Trip Time Threshold (MTTT) Real World Events : Real World Events Track out of Service High priority Train The Parametric model takes into account: Track Configuration Changes, Train Schedules, Service Expectations Steps in Capacity Planning : Steps in Capacity Planning Estimate Capacity Requirements Identify gaps Develop Alternatives Evaluate the Alternatives The Parametric Capacity Model allows us to do a “what-if” analysis by varying the parameters to have the maximum utilization of the Track Asset with minimal resources Parametric Capacity Model : Parametric Capacity Model Input Output Article Review : Article Review Theoretical Importance Measures and monitors track capacity taking a broad, system perspective Innovativeness/Originality Effective decision support tool that can be used to develop cost-effective solutions Methodologically Sound Adequacy of Literature Review Not adequate due to the absence of detailed deduction and explanation of equations and some variables Article Review : Article Review Quality of Ideas Concept can be used to simulate different plant, traffic and operating alternatives Clarity of Writing Snapshots of the Parametric Capacity Model inputs and outputs Potential to Stimulate Further Research Further research could be conducted by including additional factors such as weight and length of trains Overall Contribution Software based on this model can help in monitoring and measuring the dynamic nature of railway network capacity Slide 20: Thank You You do not have the permission to view this presentation.
