“…The model consists of some main elements: zones, nods, connectors, manoeuvres, connecting elements, stops, public transport routes. Nodes indicate the allowed manoeuvre directions and priorities (main, secondary road), street connections are described by the length, number of lanes, speed restrictions on traffic, the traffic throughput (Dell'Acqua, Russo 2010; Dragcevic et al 2008). Modelling has been performed in several stages (Fig.…”

The growing demand for transport and communication services leads to more and more important, traffic related and closely associated problems, especially in the city centre, such as traffic congestion, air pollution, noise and some others. When modelling traffic flows in the Kaunas city centre, the simulation models of crossroads were created based on the principle of cellular automaton model, taking into consideration such relevant traffic indicators as the average speed of traffic flow in diflerent streets, traffic intensity, congestions and distributed flows. Operation of cellular automaton model is associated with the improved approach of further vehicle model. Modelling of microscopic traffic flows is based on the brake light-cellular automaton (BL-CA) model. Random functions were made discreet and autocorrelation values of these functions were calculated in this work. Fundamental macroscopic traffic characteristics were obtained. Numerical dependences of the average traffic speed and traffic flow, traffic density and traffic flow, the average traffic speed and density were determined, with a help of which the demand parameters of transport network were evaluated in the Kaunas city centre in certain time intervals.

“…In this paper, two computer programs are used as user applications in AutoCAD for the purpose of swept path analysis: AutoTrack and GF (developed at the Faculty of Civil Engineering of the University of Zagreb). The reliability of these programs was verified against experimental tests of vehicle movement on the polygon [24,25]. Test results [24,25] showed that the departure from really measured values remains within the limits of accuracy of road pavement construction, and that the software programs are suitable for research involving accurate drawing of vehicle movement trajectories.…”

The design and possible simplifications of four-leg channelized intersections are analysed in the paper. The research resulted in a new simpler approach in which all intersection elements are properly formed from the very beginning, so that the need for the swept path analysis and redefining of intersection elements is rendered superfluous. New procedures for the design of four-leg channelized intersections for the 60 to 90 degree intersection angles, and for semi-trailer trucks 16.5 m in length, are presented. Novi postupak oblikovanja četverokrakih kanaliziranih raskrižja U radu se istražuje projektiranje kanaliziranih četverokrakih raskrižja i moguća pojednostaljenja. Provedeno je istraživanje rezultiralo novim i jednostavnijim pristupom u kojem su svi elementi raskrižja pravilno oblikovani od samog početka, tako da je potreba za kontrolom provoznosti i redefiniranjem elemenata raskrižja postala suvišna. Prikazani novi postupci projektiranja četverokrakih kanaliziranih raskrižja za kutove presijecanja osi od 60 do 90° za tegljač s poluprikolicom duljine 16.5 m.Ključne riječi: četverokraka kanalizirana raskrižja, nesemaforizirana raskrižja, trajektorije kretanja vozila, prometni otoci, rubovi kolnika, mjerodavno vozilo Wissenschaftlicher Originalbeitrag

The paper deals with the influence of active car safety systems on driver's behavior in emergency situations, i.e. emergency braking, steering angle, etc. Several models of real vehicles have been tested in order to analyse the ABS and ESP systems operation efficiency. The results of emergency braking and stability in real vehicle testing with ABS and ESP stability control systems switched on and off are presented in detail. In order to get the maximum impact of ABS and ESP systems (full activated) the real vehicles were tested on the asphalt paved road covered with wet snow. Tests were also carried out on the road sections with different pavement and state. The XL Meter Pro Beta measurement device was used for the real vehicle testing. The brakes and active safety systems of the vehicles have been tested for their effectiveness at different conditions: when the vehicle is braking on horizontal wet asphalt, and on an icy gravel surface, at a different initial running speed: 40km/h, 70 km/h and 100 km/h. During the real vehicle testing the stability during emergency braking resulted in the assessment of influence of active safety systems on handling the vehicle and its stability, and the driver's behaviour in emergency situations i.e. on a slippery road, or at sharp steering angle. The results of real vehicle testing have been presented in the paper in the form of charts. Examination of a vehicle emergency braking and stability systems results in the conclusions concerned with handling of the vehicle ad application of the above systems.
