The Train Diagram's Designing And Assessment Of Urban Rail Transit

The train diagram is an integrated plan of railway transportation. It's quality direct impact on the efficiency and safety of the transportation organization. The urban rail traffic passenger flow is on a random convergence of the main crowd, which leads to the unique complexity of urban rail transport, and asks for higher demand for the train diagram's performance. Use for reference from the train diagram's design and assessment of mainline railway, combining the characteristics of urban rail traffic, this paper makes exploration and research on the train diagram's design and assessment of CBTC system.Base on introduction of the basic knowledge of train diagram, this paper in detail introduces the composition structure of train diagram and analyzes the function of the various sub-systems. Paper researches the whole algorithm of drawing train diagram, and emphasizes the process of turn-back station's diagram, the line of train's entrance/exit from the yard, the line between peak an d off-peak times.Paper puts forward adjustment strategies for the train running departure from the scheduled diagram. Aiming at unavoidable train delay in urban rail traffic, which is because of various subjective and objective causes, the paper analyzes the reason and influence of train delay, and puts forward two adjustment strategies. Auto regulations, including timetable calibration, the equal interval regulation, replace train number, and manual regulation including non-stop regulation, train detaining, and so on.To ensure the system to achieve the stability, reliability and expandability, the system using object-oriented programming methods, realize the drawing and regulating function of train diagram on the Visual C++ 6.0 platform, verifying the system functions and algorithms. Combining the specific conditions of train diagram system, paper puts forward display optimization solutions.Finally, the paper makes exploration on assessment of train diagram, analyzing the diagram indicators, including static indicators and dynamic indicators. From the adjustability of train diagram, paper preliminary researches the assessment of train diagram, using expert paradigm.
