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.

Choosing a model, shaping and using a model represent a sensitive stage of the transport system planning process. Considering the fact that contemporary software packages exist, based on modern technology and long – term experience it is decided to rely on the software package PTV Vision VISUM, for forecast in the traffic in Bitola town. Synthetic model is designed by this software package, modeling is done on existing situation and model’s calibration. In this paper will be represented testing on the model for transport demand for the city of Bitola, their validation.

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.

Vehicles growth has continuous negative influence on air pollution problem especially in urban areas. Exhaust emissions from vehicles contribute for a significant amount of toxic air polluters, harmful both for the environment and health. This underlines the need for development and implementation of technological measures aimed towards emission control and reduction. Technological measures are under continuous research and innovative development, and as a result vehicles have the opportunity to be equipped with different solutions for emission control. Used technological measures at the moment, as well as the next generation measures are all included in the categorized review presented is this paper. Also, a suitable kind of technological measures for countries like Macedonia without industry for car production and with older vehicle fleet are presented.

The dynamic intensity in growth of the number of motor vehicles, and with that the high quantity of exhaust emissions, significantly contributes the air contamination and other serious problems with his quality, especially in urban places. Today, the total number of vehicles globally exceeds 800 million; from witch 300 million are loading freight vehicles. These numbers are disturbing, and the concern is that the constant growth of these vehicles and the consumption of the fossil fuels will continue to raise the negative effects on the environment through the air contamination and to cause serious health problems. In this document is given the analyses for the quality of exhaust emission of diesel engines, identification of the factors which have dominant affect, actual situation about pollution from diesel engines and conclusions about future use of diesel engines vehicles, especially in the countries which are not member of EU.

This paper investigations detail analysis of the influence the type of construction and the way of fixing seat bearers on basic bus construction and its superstructure. Before performing experimental investigations it was modeling of tension-deformation condition of across frame made by using Finite Element Methods. During experimental investigations on basis of this analysis it was founded three measuring points where deformations were measuring. According results from experimental investigations it was third type of seat bearers allowing raise of safety area of bus passenger’s.

Significant part of air pollution control strategy can be achieved through measures in urban transport planning. The need for this analysis is based on the fact that transport planning decisions are often made without proper consideration of their air pollution consequences. This inevitably deteriorates air quality in urban areas, particularly in those areas which already have problem with urban air pollution. The paper deals with transport planning approach towards reducing air pollution and this approach is analyzed through short-term and long-term measures, recommended for Bitola. Implementation of these measures has a potential to contribute for improvement of the current problem with air pollution.

For urban transport to be competitive and sustainable, it has to be smart. Cities worldwide use smart technologies to integrate transport systems, minimize costs and improve user experience. The concept of smart transport is a hot topic between city leaders looking to find a wave of innovation to more sustainable and prosperous cities [1]. The city of Skopje is on a good path towards the development of smart urban transport. Hence, the purpose of the paper is to present progress made in the city of Skopje implementing smart measures in urban transport. More important, the analysis recommends additional smart measures and directions with a potential to support and strengthen sustainable urban mobility features.

Information about non-motorized transport, i.e., cycling and walking, are needed for planning and management support of urban transport systems. However, in the city of Skopje, monitoring programs still aren’t established by transport officials on regular basis. Hence, transport planners and researchers lack bicycle and pedestrian counts for managing traffic demand. Having in mind principles for comprehensive monitoring as a framework for assessment, this paper summarizes approaches and recommendations for initiating monitoring program in the city of Skopje. Also, describes steps in establishing monitoring program and identifies possible application of the analyzed monitored data for non-motorized transport.
