To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airpl ...[more] |

The present report is organized in 4
main parts: the first one raises the various stakes of street design; the second one presents a
systemic approach to street production and locate the role of current, implicit and
unchallenged street models; the third one exposes a set of design operators that may help
urbanists and researchers to conceive new models of street; the fourth and last part deals with
first applications of these tools: the construction of a street forms classification and the ...[more] |

In this numerical study, the fuel-saving potentials of drag-reducing devices retrofitted on heavy vehicles are analysed. Realistic on-road operations are taken into account by simulating typical driving routes on long-haul and urban distributions; variations in vehicle weight are also considered. Results show that the performance of these aerodynamic devices depend both on their functions and how the vehicles are operated. Vehicles on long-haul routes generally save twice as much fuel as those d ...[more] |

Czech Science Foundation project No. 103/09/1499: Multichannel Ground Penetrating Radar as a Tool for Monitoring of Road and Bridge Structures, is solved by CDV-Transport Research Centre (2009 - 2011). The main aim of the project is a verification of potential of multichannel ground penetrating radar (GPR) as a non-destructive tool for detection of road defects and bridge defects.
Project is focused on design and practical verification of test procedures for:
-detection of voids under roadba ...[more] |

The main scientific and engineering goal of this book is to deal simultaneously with soil dynamics/vibrations and wave propagation in soils (including seismic waves). These various fields are generally considered in separate disciplines such as earthquake geotechnical engineering, civil engineering, mechanics, geophysics, seismology, numerical modelling, etc. The objective of the book is to offer in a single publication an overview of soil dynamics and wave propagation in soils with emphasis on ...[more] |

This guideline of the Ministry of transport of the Czech Republic is one result of R&D project No. 1F55B/090/120: Rigid pavements – new construction, repair and reconstruction technologies, comparison with flexible pavements and long term monitoring. The purpose of the guideline is to compare and evaluate pavement structures with asphalt courses and with cement courses and summarise all viewpoints used during selection of proper pavement type. Except for construction costs the other aspect ...[more] |

There are many locations with occurrence of accidents in the Czech Republic and we can notice unreasonable numbers of casualties and damage to health or property there. Thorough analysis of statistic data from PÈR (Czech police) made by Centrum dopravního výzkumu, v. v. i. (Transport Research Centre - public research institution) can confirm this phenomenon.
Due to the current economic situation in the Czech Republic it is not possible to ensure efficient traffic surveillance only by means of ...[more] |

In April 2007, Centrum dopravního výzkumu, v.v.i. was appointed to
coordinate a project CONGMAN – Effective traffic flow management of congestions on
motorways and dual carriageways with the use of ITS. The project is assigned by the
Ministry of Transport of the Czech Republic as a R&D project. In the first stage of the
project, the research team (CDV, Brno University of Technology, and HIT Hofman
s.r.o.) has developed an intelligent transport system for effective traffic flow
