Vision Zero from the Perspective of Traffic Psychology
Transactions on Transport Sciences 2014, 7(1):1-8 | DOI: 10.2478/v10158-012-0048-6
The presented article reflects a scientific approach to the concept of a traffic system known as Vision Zero, which was postulated in 1997 by prof. Kare Rumar in Sweden. The implications of this approach are explored in terms of psychology. Other documents of the European Commission (including "Towards a European Road Safety Area: policy orientations on road safety 2011-2020") and the development of traffic safety in the Czech Republic are also discussed. The article seeks to provide information about the vision of traffic safety in European countries, which is based on the tenet that each road fatality is unnecessary - "Vision Zero". Attention is...
Design of Algorithms for Payment Telematics Systems Evaluating Driver's Driving Style
S. Kantor, T. Stárek
Transactions on Transport Sciences 2014, 7(1):9-16 | DOI: 10.2478/v10158-012-0049-5
This article and its issue fall into the area of payment telematics systems in the transportation domain, with specific focus on the evaluation of driver's driving style. The aim of the described research is a suggestion of an algorithmic method of the evaluation of the driving style of the driver for payment telematics systems. This, in its result, allows comprehensively to take into account the differences in drivers' behaviour and therefore also the probability rate of a traffic accident. The output of the algorithm is a projection of the evaluation into insurance payment. The article points out the weaknesses and shortcomings of the Pay As You...
New Concept of Hybrid Drive with Multi-Gear Planetary Transmission
Transactions on Transport Sciences 2014, 7(1):17-26 | DOI: 10.2478/v10158-012-0050-z
Paper presents an innovative concept of a hybrid drive with two- or three-gear planetary transmission. The arrangement can be extended by one or two additional clutches. Considering the minimum of two-gear planetary transmission, the combustion engine can work in an optimum efficiency mode, i.e., with low consumption and thus with reduced emissions of pollutants, as well as in modes enabling energy storage. Individual gears of the multifunction transmission, constructed as a system as simple as possible, accommodate various driving demands, e.g., serial or parallel driving modes, or parking blockage.
Delay Function in Dependence of Dynamic Phenomena

Transactions on Transport Sciences 2014, 7(1):27-34 | DOI: 10.2478/trans-2014-0001
Knowledge of actual road traffic volume and road capacity is a part of the data necessary to know when an emergency event occurs and the traffic needs to be quickly diverted to an alternative route. The method based on Czech standards for calculating traffic volume and capacity was innovated. The first step of the method deals with the determination of road capacity depending on its category and traffic volume. The other part of the method takes into account the calculation with adverse weather conditions, such as rain or snow, low temperature and bad visibility. The latter part is derived from international studies. The actual capacity method is used...
Determination of Trajectory of Articulated Bus Turning along Curved Line
H. A. Dang, J. Kovanda
Transactions on Transport Sciences 2014, 7(1):35-44 | DOI: 10.2478/trans-2014-0002
The paper focuses on the presentation of a single-track dynamic model of articulated bus, a simplified linear model, which is based on reducing the double-track dynamic model with suitable assumptions that the front body lateral accelerations and rotational angles of the articulated bus are small. On the other hand, the phenomena of friction and interstice, such as articulated system (fifth wheel), are neglected. A coordinate system is defined to precisely describe the translational and rotational motions of the vehicle. In details, the author provides the dynamics model, sets up the kinematics and dynamic relations and builds differential equations...
Technical Note on Description of Impulse Vessel

Transactions on Transport Sciences 2014, 7(1):45-46
The biomechanical research projects deal with different fields of vehicle passive safety, especially with mechanisms of injury, their investigation and predictions of injury severity. The presented article describes a device which helps to understand the spreading of the pulse wave. It causes very dangerous diffuse brain injury, which is responsible for 75% of deaths in traffic.
