Assessment of Rail Freight Transport Service Quality

Published Online: 19 Jun 2012
Page range: 188 - 192

Abstract

Assessment of Rail Freight Transport Service Quality

Investigations show a growth of requirements for goods transportation quality by rail. There is a need to analyse in details goods transportation system by rail to meet requirements of market and give extra boost to development transportation service quality. The purpose of the current article is to give a partial overview about the experts, freight forwarders and customers' survey results. The analysis of customers' answers showed that they are not fully satisfied with quality of the service. It was identified that freight forwarders and other transportation service providers must carry out regular self-assessment of performance against defined criteria of service. Clear and united criteria of cargo transportation quality by rail will make easier to choose transport mode, transport means and route. The survey data and literature analysis showed that there is a vast range of criteria to be proposed for rail service quality evaluation, but no one of the models is prevailing. The analysis showed that most often the mentioned criteria are linked with the information, rolling stock, reliability and punctuality.

Mobile Phone Accidents - Experience Of India

Abstract

Mobile Phone Accidents - Experience Of India

Every year nearly 1.4 million people have been killed because of they are wireless customers and their over-bearing cell phones. While in India, an estimated 1.35 lakhs person died due to road accident in 2010, which is approximately 10% of road accident fatalities worldwide and these figures are the highest in the world. But still no research has been carried out to find the number of drivers using cell phone involved in road accident and very limited efforts has been carried out to prevent accident due to cell phone usage. To our knowledge this is the first survey carried out in India to determine the number of drivers involved in an accident due to mobile phone use. With the aim of preventing such accidents, it is proposed to develop a highly efficient automatic system for early detection of incoming and outgoing call, by placing an antenna along with mobile detection unit above the driver seat. This unit is capable of distinguishing whether the cell phone used either by the driver or by the passenger, if the driver uses of cell phone is detected, a safety application named Cellphone Accident Preventer (C.A.P.) which is developed using J2ME will be automatically load on the driver's cell phone which helps in eliminating the risk of accidents from occurring, at the same time ensuring that the user does not miss any emergency call. The research has been extended to show how far the system will help in preventing accidents and to what extent this system will help in reducing the Indian economic loss incurred unnecessarily due to road accident fatalities.

Consideration of the Aspects of the Transportation Systems Microscopic Model Application as Part of a Decision Support System

Abstract

Consideration of the Aspects of the Transportation Systems Microscopic Model Application as Part of a Decision Support System

The article presents the experience in using decision support system (DSS) when managing urban transport system (UTS) and a possibility of using microscopic modelling as an integral part of the decision-support system (DSS) when managing the urban TS. To illustrate the problem and a possible DSS-based solution, an example of a specific project has been examined, where microscopic modelling was used for the analysis of possible reconstruction of a transport system (TS) fragment in the city of Riga, - which was performed in 2010 in the laboratory of applied software systems of the Transport and Telecommunication Institute (in Riga). The project goal was the consideration of expediency for implementation of a pedestrian area in the street of city centre with the existing street traffic. The article formulates some problems that occurred in the process of development and application of simulation model for analysing various scenarios; some possible alternatives of their solution are suggested.

An alternative of possible DSS architecture for managing TS in Riga is suggested; some requirements to the data handling and organization in the system are examined. Special attention has been paid to the problem of synchronizing the data handling of macroscopic and microscopic models of urban TS. The article formulates the requirements to organization of data transmission interface between macroscopic and microscopic data. The suggested DSS concept can be used when solving various problems of transportation planning.

Urban Public Transport System's Reliability Estimation Using Microscopic Simulation

Page range: 219 - 228

Abstract

Urban Public Transport System's Reliability Estimation Using Microscopic Simulation

In the article the procedure of the reliability measures estimation for one route of the public transport network on the basis of a traffic flow modelling is suggested. A definition of UPTS reliability is based on the analysis of the Travel Time Reliability, Arrival Time Reliability and Probability of arriving to the stops with delay no more than m minutes. The approach is applied to the real task of the reliability estimation for Riga city public transport route. The microscopic model of transport network fragment is used for it.

Information Support System for Technology of Applying the Multi-Component Nano-Structured Protective Coatings

Abstract

Information Support System for Technology of Applying the Multi-Component Nano-Structured Protective Coatings

The given article considers the process of arranging informational support in carrying out experiments on applying the nanostructured protective covering on different materials. For nano-coverings coating, there is used special plant, which is given different modes of performance. For accounting all parameters and for accumulating the data, which characterize the results of the experiments, there is suggested an information system which employs the database designed for these purposes. The authors suggest an approach to defining the main requirements and functions of an information system on the basis of functional simulation and consider the issues of its realization. This information system also allows processing the results of the experiments with the use of statistical methods. The analytical module of the information system is supposed for solving the tasks of determining the thickness of covering depending on the specified mode of plant operation (pressure, voltage, current); it is also employed for determining what operation mode is required for receiving the covering with certain designated properties and parameters. Consequently, the task of scientific prognostication of the covering properties is solved.
