Assessment of Heavy Metal Pollution (Cd, Cu, Pb, Hg) in Urban Soils of Roadsides in Brno

A. Debnárová, H. Doleľalová Weissmannová

Transactions on Transport Sciences 2010, 3(4):147-156 | DOI: 10.2478/v10158-010-0021-1

This environmental study is focused on the distribution of heavy metals in the soils of selected localities in Brno. The soils samples were collected near roadsides and the concentrations of Cd, Cu, Pb and Hg were determined with using atomic absorption spectrometry. The contamination of soils from selected localities was evaluated on the basis of the pollution index, contamination factor and degree of contamination; and the limit contents of heavy metals in soils which is listed in the Guidance M®P Czech Republic were also used for assessing the contamination. Mercury and cadmium have been identified as the main polluting metals in selected localities...

Critical Infrastructure Safety Management

D. Procházková

Transactions on Transport Sciences 2010, 3(4):157-168 | DOI: 10.2478/v10158-010-0022-0

Critical infrastructure is a set of mutually interconnected networks, i.e., the systems of various sectors of a human system. An interconnection of systems means their mutual dependence. Therefore, in connection with safe critical infrastructure and with sustainable development potential, it is necessary to solve several problems, namely the safety of partial infrastructures and the safety of a set of mutually dependent infrastructures. With regard to present knowledge we know that the optimum safety of the set of infrastructures is not the set of optimum safeties of partial infrastructures, and, therefore, we must search for a solution in a different...

Abdominal Finite Element Model for Traffic Accidents Injury Analysis

L. Ondoková, L. Hynčík

Transactions on Transport Sciences 2010, 3(4):169-178 | DOI: 10.2478/v10158-010-0023-z

The abdominal cavity is a vulnerable region of the human body. The severe and critical abdominal injuries arising during traffic accidents are the second most important bodily injuries after thoracic injuries. The injuries are predominantly caused by contact with the lap belt, steering wheel, armrest, dashboard, side door, etc. However in terms of investigating the biomechanical response of the abdomen, experimental studies have turned out to be particularly difficult to perform and the results obtained are not easy to interpret. Therefore attention should be paid to a generation of more realistic human body models with detailed inner organ models...

The Synergy Transportation

V. Vlčková, Z. Votruba

Transactions on Transport Sciences 2010, 3(4):179-186 | DOI: 10.2478/v10158-010-0024-y

Paper reflects the aspiration to denominate the relation between transportation and fields of environmental and nature phenomena, following and having respect for the principles of sustainable development. Systems knowledge and methodologies are used: Systems approach; methodologies of synergy and principles of sustainable development. The Theory of Production Function is extended to tackle these problems.

Dynamic Tests: Passenger Car vs. Child Pedestrian

Z. Schejbalová, A. Kváąová, Z. Marek

Transactions on Transport Sciences 2010, 3(4):187-196 | DOI: 10.2478/v10158-010-0025-x

The Department of Forensic Experts in Transportation at the Faculty of Transportation Sciences performed a second set of dynamic passive safety tests on a passenger car (M1 category - ©koda Octavia II) in a child pedestrian collision. Initial and test conditions were similar to those that were made in the first set of tests in September 2009 (©koda Roomster). Deformations of contact zones on the frontal vehicle surface were analyzed by 3D scanning technology (3D handy scanner). Head, thorax and pelvic resultant acceleration, acceleration of knee joint in sagittal direction and the contact force on the femoral structure of the dummy (P6 dummy, 1.17m;...

Technical Note on Design of Suspension Parameters for FSAE Vehicle

O. Suchomel, B. Ruzicka

Transactions on Transport Sciences 2010, 3(4):197-203

Correct suspension parameters determination is one of the most important design issues in the development of each type of car. The aim of the suspension design in the field of race cars is to provide ideal operating conditions for the tire and to allow it to generate the maximum amount of traction, braking and lateral forces which determine a vehicle's acceleration capabilities. This article describes the determination of the Formula Student/SAE car suspension parameters related to the vertical dynamics of the car as a basic point in tuning up the suspension on the car itself in real operating conditions.
