Numerical Synthesis of the Track Alignment and Applications. Part I: The Synthesis Method

Mădălina DUMITRIU

This paper features a method to synthesize the track irregularities, by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method thus suggested allows a convenient formulation of the limits of the interval specific to the wavelengths of the track lateral irregularities, so that it will be representative for the frequency range of the ve(..)

A Study of the Dynamic Parameters Influence over the Behavior of the Two-Section Articulated Vehicle during the Lane Change Manoeuvre

Rusi Rusev/ Rosen Ivanov/ Gergana Staneva/ Georgi Kadikyanov

The course stability and the steerability of the two-section wheeled vehicle at high velocities during the lane change manoeuvre are studied in this paper. Mechanic-mathematical model is developed, on which base simulation programmes are elaborated. Simulation studies of the course stability at different velocities depend on some constructive and exploitation factors are made by these models. Based on the simulation results an idea for an algorithm and a semi-active control system of the resista(..)

Evaluation of the Transition to the Organization of Freight Trains Traffic By the Schedule

Dmitriy KOZACHENKO/ Roman VERNIGORA/ Vladimir BALANOV/ Nikolay BEREZOVY/ Lidiia YELNIKOVA/ Yulia GERMANYUK

The paper considers the issues of bulk conveyance organization between industrial enterprises on schedule. Currently the movement of the main part of freight trains is performed on preparedness and occupation processes of separate schedule train paths by some terminals are not fixed. And, due to the lack of statistical material on the punctuality of the schedule for the movement of freight trains, research of the passenger trains movement with subsequent dissemination of results on freight movem(..)

The Determination of Admissible Speed of Locomotives on the Railway Tracks of the Republic of Kazakhstan

Seidulla ABDULLAYEV/ Natalyа TOKMURZINA/ Gabit BAKYT

Today modern locomotives of KZ4AC, KZ8A, TE33A series were put into service in the Republic of Kazakhstan. In order to establish safe operating mode of these locomotives the admissible speed on the railway tracks of the Republic of Kazakhstan was determined. The admissible speed of locomotives was determined on the basis of analysis on the results of dynamic and railroad tests and calculations for stress of railway construction.

Speed Compliance in Freeway Variable Speed Limit System – Case Study of the Prague City Ring

Michał MATOWICKI/ Ondřej PŘIBYL

Many previous studies have confirmed the strong relationship between speed compliance and the frequency and severity of traffic accidents. Variable speed limit (VSL) system as a measure to improve traffic safety enables the freeway system to change its posted speed limit based on various traffic and environmental conditions. Such system helps drivers to recognize the upcoming events, to adjust their driving style and in such way to address speed variation of the traffic flow. This is called spee(..)

Analysis of the Force during Overcoming the Roadblock – The Preliminary Experimental Tests

Jakub POLASIK/ Konrad J. WALUŚ

The paper applies to the issue of preservation of passenger vehicles during overcoming the roadblocks on a dry asphalt surface with the constant speed. The study aimed to estimate the forces which are affecting the suspension of the vehicle during the contact between a tyre and roadblock. Using the video recording it is possible to calculate the values of the tyre deflection and forces acting in the system. The obtained deflections of the tyres were compared to earlier laboratory test results an(..)

Signal Controlled Junctions Calculations in Traffic-Capacity Assessment - Aimsun, Omnitrans, Webster and TP 10/2010 Results Comparison

Ľubomír ČERNICKÝ/ Alica KALAŠOVÁ/ Ján KAPUSTA

Every increase in traffic volume on road network in towns can lead to overcrowding of road network. This results in undesirable external costs such as traffic congestions, which cause high loses in time during transportation, increased fuel consumption and thus higher production of greenhouse gases and noise. This all ultimately reduces the attractiveness of the area. The increase of traffic volume and therefrom derived traffic problems are needed to be solved during traffic-capacity assessment (..)

The paper presents the research results of cuts braking modes on the gravity humps. The objective of this paper is developing the methods for assessment of braking modes of cuts under conditions of fuzziness of their rolling properties, as well as selecting the permissible starting speed range of cuts from retardant positions. As a criterion for assessing the modes of target control of cut rolling speed, it was proposed to use an average gap size on a classification track at the established norm(..)
