A STUDY ON COOPERATION OF URBAN TRANSPORT MEANS: PRT AND LIGHT RAIL

Waldemar GRABSKI/ Wiktor B. DASZCZUK

It is difficult to organize urban transport in the city center. Existing buildings, narrow streets and working infrastructure make it difficult to use the oldfashion transport means such as trams or buses. The new idea consists in elevation of the transport in the very city above ground level (typical PRT systems cover rare areas like airport or fairgrounds). The study analyzes the hierarchical, layered system consisting of a ring light rail and PRT (Personal Rapid Transit) serving as commuter n(..)

THE EFFICIENCY OF TRANSPORTATING PERISHABLE GOODS BY ROAD AND RAIL

Mariia OLKHOVA/ Yurii DAVIDICH/ Dmytro ROSLAVTSEV/ Nataliia DAVIDICH

This research analyses the competitive advantages of road and rail transport through the example of Ukraine transportation market. Spheres of efficient usage of rail and road transport while transporting perishable goods have been studied. The key factors influencing the mode choice, as well as the kinds of cargo that depend on the mode choice have been determined with the help of revealed preference data. A mathematical model of mode choice has been offered. The criterion of the effectiveness o(..)

FINANCING PUBLIC TRANSPORT SERVICES FROM PUBLIC FUNDS

Miloš POLIAK/ Štefánia SEMANOVÁ/ Michaela MRNÍKOVÁ/ Lenka KOMAČKOVÁ/ Patrícia ŠIMURKOVÁ/ Adela POLIAKOVÁ/ Salvador HERNANDES

The paper deals with the issue of efficiency of public passenger transport through financial support from public funds from the perspective of improving road safety. The aim is to verify the hypothesis that financing public passenger transport from public funds is a significant tool to influence the number of passengers carried by individual automobile transport, and thus it can be used a tool for influencing road safety in a particular territory. The first part of the paper analyses the sources(..)

FORMING DELIVERY ROUTES WHILE PROCESSING THE STOCHASTIC FLOW OF REQUESTS FOR FORWARDING SERVICES

Vitalii NAUMOV

Formation of rational delivery routes is the main way to increase the effectiveness of client services for freight forwarding companies. The main part of the requests for transport services comes from occasional (non-constant) clients. The set of those requests forms a stochastic flow. For stochastic requests flow, the delivery routes are formed in the process of the requests receipt. Therefore, the standard approaches for merging of requests from multiple clients into routes, based on linear pr(..)

INFORMATION SUPPORT OF DECISION MAKING IN URBAN PASSENGER TRANSPORT MANAGEMENT

Vladimir NEMTINOV/ Yulia NEMTINOVA/ Andrey BORISENKO/ Vladimir MOKROZUB

In this paper, we examine the problems of simulating modeling of urban transport route network operation and development of an information system for automating the process of modeling and processing of simulation results with SIMUL8 software. In order to solve this problem, it is required to solve the following set of related tasks: formal description of the urban transport systems structure and parameters of its functioning, development of mathematical models of urban transport network perform(..)

SELF-DIAGNOSIS METHOD FOR CHECKING THE WAYSIDE SYSTEMS FOR WHEEL-RAIL VERTICAL LOAD MEASUREMENT

Daniele CORTIS/ Stefano GIULIANELLI/ Gabriele MALAVASI/ Stefano ROSSI

Nowadays, wayside measurement systems of wheel-rail contact forces have acquired great relevance for the monitoring of rolling stock, especially for freight trains. Thanks to these solutions, infrastructure managers can check and monitor the status of rolling stock and, when necessary, impose corrective actions for the railway companies. On the other hand, the evaluation of contact forces is part of the rolling stock authorisation process [1] and a mainstone for the study of the running stabilit(..)

USE OF AN AUTOMATON MODEL FOR THE DESIGNING OF REAL-TIME INFORMATION SYSTEMS IN THE RAILWAY STATIONS

Igor ZHUKOVYTS’KYY

The author proposes to develop special models that are built based on finite-state machine, Mealy, in order to display information about technological processes at railway stations. The input alphabet of such machines is represented by the real signals (from the floor equipment, the related information systems and the dispatch office personnel). This representation allows one to formalize the software design process of real-time information management systems for these technological processes. T(..)
