The Method Of Calculating The Middle Simple Locomotive And The Train Composition In The Turnover Point Based On The Modeling In The Conditions Of A Pair Traffic Of Trains, M.N. Masharipov
Journal of Tashkent Institute of Railway Engineers
The article developed a method for calculating the average downtime of a locomotive and the composition of a train at a turnaround point based on modeling in a pair train schedule. As a result of this, it is scientifically substantiated that strict adherence to the principle “trains do not expect a locomotive” will lead to a significant increase in the cost of locomotive hours at the point of turnover

Graduate Theses and Dissertations
This project evaluates the performance of Weigh-in-Motion (WIM) auto-calibration methods used by the Arkansas Department of Transportation (ARDOT). Typical auto-calibration algorithms compare the WIM measured weights of vehicles from the traffic stream to reference values, using five-axle tractor-trailer configured trucks for comparisons, e.g. Federal Highway Administration (FHWA) Class 9. Parameters of the existing algorithms including the Front Axle Weight (FAW) reference value, the sampling frequency required to update the calibration factor, and thresholds for Gross Vehicle Weight (GVW) bins were evaluated. The primary metric used to estimate algorithm performance was Mean Absolute Percent Error (MAPE) between the WIM and static …

Pedestrian simulation modeling has become an important means to study the dynamic characters of dense populations. In the continuous pedestrian simulation model for complex simulation scenario with obstacles, the pedestrian path planning algorithm is an indispensable component, which is used for the calculation of pedestrian macro path and microscopic movement desired direction. However, there is less efficiency and poor robustness in the existing pedestrian path planning algorithm. To address this issue, we propose a new pedestrian path planning algorithm to solve these problems in this article. In our algorithm, we have two steps to determine pedestrian movement path, that is, …
