ON A FAIR MANIFOLD FARE RATING ON A LONG TRAFFIC LINE

Stanislav PALÚCH/ Tomáš MAJER

The paper studies the possibilities to design a fair manifold tariff on a long traffic line. If a single tariff is used on a long bus or railway line, passengers travelling long distances are favoured at the expense of those travelling short distances. The fairest approach to tariff is setting an individual tariff for every origin–destination relation of line stops that expresses real travel costs. However, sometimes the individual tariff is too complicated and is therefore replaced by double-, (..)

USING A WHEEL PAIR WITH A COUNTER-FLANGE TO PREVENT DERAILMENT

Yuriy Iv. OSENIN/ Larysa DEGTYAREVA/ Galyna OSENINA/ Oksana SERGIENKO

The authors propose an engineering solution for a wheel pair with a counter-flange that satisfies the existing standards of vertical and horizontal dynamics and the movement stability index. An improved profile of a rail wheel with a counter-flange is developed. It provides additional contact in the horizontal plane in the situation of transverse vibrations of the wheel pair against the rail track, adds to carriage stability and increases the wheel’s resistance to derailment when passing a curve(..)

GEOMETRIC ANALYSIS OF MANEUVERABILITY PERFORMANCE FOR VEHICLES WITH TWO STEERING AXLES

Jędrzej PILISIEWICZ/ Roman KACZYŃSKI

One of the most important features of motor vehicles is their steering maneuverability. Ways of determining single axle steering are well known. This paper presents an idea of how to determine maneuverability of motor vehicles with two steering axles. The concept makes use of elements of kinematic analysis as well as of a 3D model of the steering system. It is based on the theoretical analysis of the most unfavorable situations, such as parallel and perpendicular parking techniques, on the basis(..)

IMPACT OF ROAD GEOMETRY ON VEHICLE ENERGY CONSUMPTION

Blaž LUIN/ Stojan PETELIN

It has been shown that road geometry has a great impact on overall energy consumption and emissions. Some roads connect traffic origins and destinations directly. On the other hand, some use winding, indirect routes. Indirect connections result in longer distances driven and increased fuel consumption. A similar effect is observed on congested roads and mountain roads with many changes in altitude. Therefore, we propose a framework to assess road networks based on energy consumption. This framew(..)

PROBABILISTIC MODEL FOR AIRPORT RUNWAY SAFETY AREAS

Stanislav SZABO/ Peter VITTEK/ Jakub KRAUS/ Vladimír PLOS/ Andrej LALIŠ/ Marek ŠTUMPER/ Iveta VAJDOVÁ

The Laboratory of Aviation Safety and Security at CTU in Prague has recently started a project aimed at runway protection zones. The probability of exceeding by a certain distance from the runway in common incident/accident scenarios (take-off/landing overrun/veer-off, landing undershoot) is being identified relative to the runway for any airport. As a result, the size and position of safety areas around runways are defined for the chosen probability. The basis for probability calculation is a p(..)

INVESTIGATION INTO THE BIMODAL TRANSPORTATION PROCESS BY MODELLING RAIL MODULE STATES

Оleksander LAVRUKHIN/ Victor ZAPARA/ Yaroslav ZAPARA/ Olga SHAPATINA/ Ganna BOGOMAZOVA

The bimodal transportation process, which takes into account the modelling of rail module states, has been studied. The article demonstrates marked graphs of rail module states with and without running gear change in operation. It has been established which states have the greatest impact on the probability of a steady mode. The work has considered fractality of arrivals and its range in the queueing system with priorities.

IMPROVING THE ORGANIZATION OF THE SHOVEL-TRUCK SYSTEMS IN OPEN-PIT COAL MINES

Mark KORYAGIN/ Artyom VORONOV

The aim of the study is to reduce idle times of mining trucks and shovels in an open-pit coal mine. A heuristic algorithm for making dispatching decisions in conditions of dynamic allocation of trucks is developed. Priority parameters for choosing the shovel after the end-of-truck unloading are introduced. Also, an algorithm for searching for the optimal priority parameters to satisfy the required efficiency criterion is developed. This algorithm is based on a simulation model of a shovel-truck (..)
