This paper presents the movement dynamic of the train and the relationship between the speed of wheel and train, as well as a discussion about the concept of wheel slip. There are two different operation regions designated as creep and wheelspin areas for wheel slip. Creep and wheelspin areas have stable and unstable characteristics, respectively. Wheels and rails are constructed from iron, and...

This paper considers the second-best policy problem that arises when auto travel is priced below its marginal cost and there is a substitute mass transit mode. We analyze the problem by combining a model of a rail line based on Kraus and Yoshida (JUE (2002)) with the highway bottleneck model. The model involves a transit authority which optimizes, in addition to the fare, two dimensions of tran...

Train crew management involves the development of a duty timetable for each of the drivers (crew) to cover a given train timetable in a rail transport organization. This duty timetable is spread over a certain period, known as the roster planning horizon. Train crew management may arise either from the planning stage, when the total number of crew and crew distributions are to be determined, or...

Among the most commonly used methods of scheduling train stops are practical experience and various “one-step” optimal models. These methods face problems of direct transferability and computational complexity when considering a large-scale high-speed rail HSR network such as the one in China. This paper introduces a two-stage approach for train stop scheduling with a goal of efficiently organi...

Automatic Train Operation (ATO) is one of the most important functions for an advanced train control system in high-speed railway systems. Research on optimization methods for ATO has been done before it is implemented in a train control system. From a theoretical point of view, it can be formulated as one of the functions of multi-objective Optimal Control Theory. This paper presents a new mul...

Railway planners have several tools to simulate the operation. Simulation allows the evaluation of the railway system’s quality by different points of view. Analyses of timetable stability and robustness include several indicators: recovery time and total delay among others. This paper formulates a model to describe the delay on a railway line. The total delay is characterized as a polynomial f...

With the increased availability of cheap and reliable depth sensors, imaging systems can now use depth information to better detect and locate objects in a scene. New augmented reality (AR) systems, such as the Microsoft HoloLens, are now mounting depth sensors on their glasses to improve functionality. The motivation behind our project is to perform object recognition using RGB-D (color and de...
