    Trans Motauto World, Vol. 4 (2019), Issue 1, pg(s) 24-27

    Transport has irrepressible contribution for the effective development of economy and society. But, these contributions are exceeded by harmful environmental consequences that transport growth causes especially in urban areas. Air pollution, acid rain, noise, climate change are just few of the problems which every urban area is dealing with. Hence, it is very important to provide development of the transport that at the same time could increase its sustainability and minimize environmental degradation. Numerous sustainable transport solutions are available with a potential to decrease these negative influences and promote mobility with higher sustainability. This paper presents a review of sustainable solutions, successfully applied in practice, as guidance for those urban areas that are dealing with the environmental problems from transport, but still are a step behind in undertaking activities.

    TRAFFIC AND DRIVERS SYMBIOSIS: MANAGING BOTH FOR LOWER AIR POLLUTION

    Machines. Technologies. Materials., Vol. 11 (2017), Issue 12, pg(s) 587-590

    Air pollution problems in urban areas mainly can be connected with the high amounts of toxic exhaust emissions, generated from the growing use of vehicles that use fossil fuels. Roads in urban areas are full with vehicles, and their management is important not just for smoothing traffic flows, but also for reduction of air pollution. Various ways could be considered in which traffic management can affect local air pollution. But, is not just traffic management that should be considered solely. Attention should be given to the behavior of the drivers, which also has his impact on air pollution levels. Therefore, the purpose of this paper is to show the importance that traffic control and management as well as drivers’ behavior together have on exhaust emission pollution. In addition to that, measures with their effects in the both categories: traffic management and drivers’ behavior are proposed.

    DATA COLLECTION AND ANALYSIS TO IDENTIFY THE TRAFFIC PROBLEMS OF THE EXISTING NETWORK AND APPLICATION OF SOFTWARE FOR SOLUTION PROPOSALS, A CASE STUDY

    Machines. Technologies. Materials., Vol. 11 (2017), Issue 11, pg(s) 553-556

    The development of information technologies are taking part in all spheres of human lives. In the traffic engineering shows a big need for application of advanced computing tools.

    Softwares for traffic analysis except that allow precise, visual and multifactor analysis of the imagined or proposed traffic solutions, they save time and money as opposed to the site testing. For proper development of the traffic, it is needed detailed and comprehensive planning of the process that will contribute to improving the traffic infrastructure.

    One of the crucial steps before using any software for traffic analysis is the collection of data with purpouse to establish the relevant traffic loads for the examined area. Namely, to get the real realistic picture of the traffic situation, it is necesarry recording the traffic to get daily, monthly and annual imbalance on traffic intensity in the investigated location. From the data obtained, the software will use the relevant data that realistically reflect the traffic situation.

    In the present work will be shown simulation of the most critical crossroads in the town of Gostivar in the two versions of existing and newly-condition situation using the software tool PTV VISSIM 7. Here will be analysed the most important parameters of the current traffic flow – the time losts in order to indicate the need of change the way of the traffic management of this intersection.
