Limits of Environmentally Friendly Transport
I. Drahotský, A. Peltrám
Transactions on Transport Sciences 2009, 2(2):36-41 | DOI: 10.5507/tots.2009.007
For railway transport to be more environmentally friendly than road transport it is necessary to reach more than the minimum occupancy and load in passenger trafficking and in freight trafficking respectively. It is not of great use to compare average values, e.g., of consumption of energy and emissions of elements of greenhouse gases; a better option is to compare the consumption of fuel per passenger and the same in the case of emissions. When comparing two vehicles of the same or comparable modes of transport (buses, railway units) in local and regional passenger traffic we can describe, with an acceptable simplification, the point of intersection...
Involvement of Aviation Activities in the Scheme for Greenhouse Gas Emission Allowance Trading
Transactions on Transport Sciences 2009, 2(2):42-47 | DOI: 10.5507/tots.2009.008
The European Union includes the Environment as one of the four main target areas requiring greater effort. One pillar of EU environmental policy is the Greenhouse Gas Emission Trading System. In the EU directive 2008/101 it was held that aviation will be added to the system of greenhouse gases trading. Despite the relatively low volume of aviation emissions, the danger of aviation emissions emitted in the higher atmosphere tips the scales. Aviation will be part of the ETS from year 2012, but the most important decisions and customizations of the ETS system for aviation are to be done now. The involvement of aviation in the ETS presents many difficulties...
Solar Cars and Energy Effiecient Management System
J. Koloc, M. Šimánek
Transactions on Transport Sciences 2009, 2(2):48-59 | DOI: 10.5507/tots.2009.009
This paper summarizes the basic assumptions that led to a thesis which investigates the use of high efficiency solar cells used by solar cars, with the main aim of minimizing energy consumption in such a vehicle. A solar car is special in the way that there is not only energy consumed, but also generated. This energy should be used in the most efficient way, for example with the use of a combination of different energy storages, such as high efficiency batteries and super capacitors.
Tracing Traffic Information Identity in Distribution Systems
P. Bureš, J. Vlčinský
Transactions on Transport Sciences 2009, 2(2):60-67 | DOI: 10.5507/tots.2009.010
Tracing messages and information passing through a distribution system is necessary for resolving problems and improving performance. This paper summarizes the requirements, analyzes the aspects, proposes a conceptual approach, gives an example of possible implementation, and summarizes the findings. A number of challenges are uncovered, for example prescribed identification schemes in the system; versioning; repetition of incoming and outgoing messages; multiple output channels; recycling of IDs; invalid messages, etc. The key requirement is to trace messages with information on the input and output of the distribution system by assigning the proper...
Driver Behavior Influenced by an Aggressive Factor
J. Faber, Z. Lisá, M. Novák
Transactions on Transport Sciences 2009, 2(2):68-73 | DOI: 10.5507/tots.2009.011
This paper presents systematic research dealing with aggressive driving in the Czech Republic. There is limited information concerning reckless driving, aggressive driving or road rage either in the Czech Republic or in European Union. A lot of opinion polls were carried out, unfortunately based on subjective feelings, which refer to some differences (e.g. gender or age). The systematic survey of driver's behavior, which proceeds further in cooperation with Faculty of Transportation Science, Ministry of Transport and Police Headquarters, is helping to describe the aggressive behavior of drivers in the Czech Republic and suggest possible ways to avoid...
Bonding of Structural Parts of Vehicle Bodies and Aspects of Passive Safety
J. Kovanda, T. Růžička, M. Kepka
Transactions on Transport Sciences 2009, 2(2):74-85 | DOI: 10.5507/tots.2009.012
Many new materials, technologies and new structural solutions are applied in vehicle bodies. With the application of new, non-conventional materials we obtain better capabilities, a higher level of safety, and, last but not least, weight reduction. At a time when energy savings are sought after, weight reduction is a great motivational factor for the application of composites, aluminium and magnesium alloys, etc. The use of nonconventional materials is connected with requirements for a different technology for the manufacture of vehicle bodies, as well as the issue of mutual connection of individual parts. Completely different actions, which we are...
