  • IMPORTANCE OF TRAFFIC SAFETY AND ENVIRONMENTAL PROTECTION IN SERBIA

    pg(s) 3-5

    This paper is devoted to traffic safety and environmental protection in Serbia. Unfortunately the level of air pollution i.e. the level of emission of carbon dioxide in the world is still raising. Additional actions are needed in order to limit the effect of climate changes in the following years. People ask why electric vehicles aren’t main-stream? It seems that price has a lot to do with it. The Road Traffic Safety Agency with its systematic and responsible activities set clear guidelines for the monitoring and improvement of road safety in Serbia. In the Republic of Serbia from 1981 till 2013 in the traffic accidents 41.718 persons were killed. In the same period 632.936 persons were seriously injured. Republic of Serbia on the 16th of November 2011 began to commemorate the World’s Day of memory on victims in the traffic accidents. Law on road traffic safety came into effect in the Republic of Serbia in 2009. and brought many changes in our legal order. Majority of those changes meant harmonization with European Union regulation in the area of traffic safety. Changes made by the st new Law on infractions (“Officaial Gazette of the Republic of Serbia“, no. 65/13) in application from March the 1 2014. show the increase of penalties for unscrupulous drivers, but drivers complain on to many regulations and difficulties to get documents for motor vehicle use. In this paper there are mentioned the most efficient hybrids we can buy today. In Serbia “FIAT automobiles of Serbia” is still the leading exporter on the list of 15 biggest Serbian exporters, according to the data of the Serbian Ministry of Finances. In April 2015 at New York Auto Show will be possible to see all new accomplishments in auto-moto industry all over the world.

  • EQUIPMENT OPTIMIZATION IN REGIONAL AGRICULTURAL LOGISTICS CENTERS

    pg(s) 17-18

    A regional agricultural center is a key link in the system of supplying Georgian standard citrus cultures to the goods markets of European countries. The elements of such logistics centers are united into three groups which comprise three large logistics divisions – supply, production and distribution.

    Optimization of the production subdivisions and technical equipment is carried out on the basis of optimizing the whole center by developing a simulation model based on statistical modeling of random streams. At first, a structural-parametrical (qualitative) model of agricultural center was developed. For optimizing the center’s technical equipment and operating standards, the combined optimization parameters have been developed. Based on the objective function formalization, there has been developed a system model of planning and optimizing of agricultural center by developing the system constraints. Optimization and algorithmization of subdivisions and the whole system are carried out by decomposition of model on separate blocks, which correspond to separate subsystems of the center.

  • ACTUAL ACCELERATION, VELOCITY AND TRAVELED DISTANCE PROFILES OF VEHICLES IN URBAN ENVIRONMENT AS DOMINANT MICROSCOPIC TRAFFIC FLOW PARAMETERS

    pg(s) 44-2

    In this paper we have presented a methodology used to determine actual acceleration, velocity and traveled distance profiles of vehicles of different categories in urban environment, as dominant microscopic traffic flow parameters. The tests have been done on representative arterial road in the city of Skopje. Within a period of one month, we have been observing the traffic on the subject arterial road and have determined the average traffic flow during different day periods. The structure of the traffic flow has also been analyzed. In the experiment we have used a probe vehicle equipped with adequate measuring system to follow more than 130 vehicles of different categories on the observed arterial road, imitating i.e. reproducing their behavior as much as possible. The final goal to determine the domains of these microscopic traffic flow parameters in specific velocity intervals, regarding different vehicle categories was reached. These results have shown to be very useful as input parameters in the single lane urban traffic flow simulator that we have developed.
