Evaluation and Classification of the Dummy Loadings Regarding Biomechanical Protection Criteria during a Bus Rollover

M. Kalinský, J. Pavlata

Transactions on Transport Sciences 2008, 1(2):51-60 | DOI: 10.5507/tots.2008.008

This paper presents simulation experiments and follow-up investigations of the passengers' biomechanical criteria during the rollover of various types of busses. The evaluation process focuses mainly on the reduction of the risk of injury. The partial aim is to indicate the influence of the safety restraint systems.

Interpretation of the Galileo Safety-of-Life Service by Means of Railway RAMS Terminology

The Galileo Safety of Life (SoL) - Level A service has been designed mainly to support aeronautical operations ranging from en-route up to approach with vertical guidance (APV II). This is why the Galileo SoL Service has been specified by means of quality criteria coming from ICAO's (International Civil Aviation Organization) Required Navigation Performance (RNP) concept, i.e., in terms of accuracy, integrity, continuity, and availability. However, Galileo SoL - Level A service is also intended for railway signalling which is based on a different safety philosophy. The objective of this paper is to describe links among the Galileo quality criteria...

Limitation of Geosynthetics Usage on Road Subgrade

There are several ways of geosynthetics functionality. Well-known mechanisms are functions of separating, filtrating, protecting and slope reinforcing. There are several publications describing the influence of geosynthetics on increasing the soft-soil bearing capacity and their positive role on final subbase deformation. However, this geosynthetics functionality has not been explained satisfactorily in detail yet. The research presented here deals with clarifying the possible geosynthetics functionality. Six kinds of geosynthetics of world renowned producers were selected for testing. The measurement was carried out in the Geotechnical Laboratory...

Pollution of the Highways Runoff

This paper collates the final results of the project dealing with the quantity and quality of highways rainfall - runoff. Field investigation was carried out through the period 2005 - 2007 on several stretches of D1 highway Praha - Brno. Low contents of the EU priority dangerous substances in surface runoff, which depends on the character of sampling and level of traffic intensity, were found. An impact on the water ecosystem, mainly on the algae Scenedesmus quadricauda, was confirmed through ecotoxicity testing. The measurement of precipitation and outflow has also brought findings about the variability of runoff coefficient in this built up transport area.

Key Attributes of the High Speed Rail System Project

L. Týfa

Transactions on Transport Sciences 2008, 1(2):87-94 | DOI: 10.5507/tots.2008.012

The contribution focuses on the provision of the high speed railway lines (HSRL) in a region, in which the HSRL is being considered. Defined first is the high speed rail system concept, followed by a description of the procedure preceding the implementation of such a railway line, and the basic principles of the HSRL route layout.
