Optimization of Fuel Costs Using the Information System

The paper deals with optimizing fuel consumption through the use of information system in road freight transport. The aim is to calculate and compare the costs for an operation with the information system as well as without it.

Measurement of the braking distance in dependence on the momentary vehicle weight

The braking distance is one of the most important features of the braking system of a vehicle during its operation. The distance depends on many factors related to technical part of the vehicle, road surface or the driver. This paper focuses on the examination of the impact of the momentary weight of the vehicle on its braking distance. It aims at explaining the issue through practical tests and drawing conclusions for further research and practical application in expert activities.

The Application of Automatic Identification Technologies by the Czech Post

This article deals with the question of practical use of automatic identification technologies in postal sector, with special focus on using barcode technologies and radio frequency identification in Czech Post. After introductory section, which is aimed at description of current situation and analysis of crucial factors of choosing automatic identification technologies, there are subchapters discussing the theoretical base of both technologies, as well as their practical use in postal sector. In the part of practical application of both identification technologies is specified the basic structure of barcodes used by Czech Post and also the description of international project UNEX, which deals with the measurement of the quality aspects of selected postal products and services. Concluding part contains a brief outline of possible radio frequency identification technology application.

The analysis of safety on Polish roads between 2000 - 2010

This article provides an assessment of the security situation on Polish roads. Statistical data on road accidents that occurred in different provinces in late 2000 - 2010 were analysed and the attention was drawn to the differences in the number of road accidents recorded between them.

The Genesis and Metamorphoses of Risk

Each business activity and also an individual person face risk every day. But what is risk? People have different attitudes to risk. Natural survival instincts make some people use all possible means to avoid injury or loss. These decisions are not decisions but more of inner instincts of survival. If we move from an individual to an organization, standards and rules become more complex and more formal. When activities become more complex, instinctive and institutional patterns of behaviour forming the basis of personal risk management become inadequate and decisions become more complicated. The theory of risk has been a subject dealt with in many available books by domestic and foreign authors and risk management as such has been a subject of detailed research. We can even claim it constitutes an independent part of the theory of economy.

The Risk Analysis in Public Passenger Transport

Possible repair methods of concrete retaining wall

This document gives instruction and information about remediation of transport retaining walls. Concrete and reinforced concrete retaining walls in terms of proposal and workmanship in comparison with many other structures can be considered less demanding. Unfortunately, this fact does not apply every time and we have to solve compromise proposals for remediation. Calculation of load would also not be problematic even for a less ambitious structural engineer. Also, design principles, and most simple form should not bother anyone. The ways of remediation described in this article can be applied to other concrete structures, whether they are retaining walls and noise barriers along roads or railways.

The measurement of contact surface of dunnage bag used for cargo securing in different gaps between cargo

This article provides comparison between the measured values of dunnage bag restraining forces and calculated values of restraining forces according to the draft version of Guidelines for Packing of Cargo Transport Units (CTU Code) for the dunnage bag of dimensions 60x120 cm and maximum filling pressure 0.2 bar.
