Abstract At present, high traffic intensity level on the roads currently saturates a great demand for individual transportation. Mobility is an important part of everyday activities in cities. The increasing number of passenger and freight vehicles on the widening transport infrastructure raises several problems. The range of use of public passenger transport does satisfy enough the citizens needs and its use is constantly decreasing, especially in the new EU countries. One of the reasons is also the growing sale and production of new passenger cars in the EU, resulting in congestion in the road infrastructure of cities and environmental problems. These issues are dealt with the modern City Logistics concept. The contribution focused on the basic principles of city logistics, the reasons for its development and, in particular, the possibilities of practical use. An example is the city of Trenčín in Slovakia, where a regional rail passenger transport is proposed for city traffic service including Park and Ride system.

The advantages of using motor transport for transportation of goods are substantiated. On the basis of an analysis of the indicators of the volume of transported goods and the turnover of goods of motor transport in a number of countries of Europe (Austria, Great Britain, Spain, Italy, Poland, Finland, France, the Czech Republic, Sweden), reduction of activity in the field of road transportation of goods in 2013 − 2014 and its activation in 2015-2016 are established; in addition, the influence of such negative environmental factors on the activity of road transportation of goods as reduction of the trade turnover of these countries with Russia as a result of the EU sanctions, increasing competition in the road transportation market, and the strengthening of the EU requirements for rolling stock and social guarantees for transportation workers was identified. The statistical data on the volume of transported goods and goods turnover of motor and all types of transport during 2012 − 2017 in Ukraine was explored, and a number of problems were identified that hinder the development of this sphere of activity, the main of which are: low quality of transport infrastructure and, above all, unsatisfactory conditions of road communication lines and corruption in the road construction sector, resulting from inefficient management of the field of activity; low level of safety control as far as road traffic and environmental protection are concerned; environmental pollution by road transport with emissions of harmful gases and transport noise, etc. The basic areas of the development of the sphere of road transportations of goods and of the network of highways are determined.

Transport as a key factor Transport as a key factor that directly influences the rapid development of any social system is in turn directly linked to the quantitative and qualitative changes of other types of productive forces. The transport service is not only important in the solution of economic tasks, it also helps to develop the road network, bring the village closer to the city, facilitate the permanent work of local personnel and rational use of labor resources. It is worth noting that transport services are also crucial in areas such as enhancing state defense capabilities, strengthening its combat capacity and prompt delivery of relevant content to its intended destination. The research paper is a contribution to the science-based system of economic indicators that create the conditions for increasing the efficiency of transport services and that will be useful for controlling the targeted use of available resources. There are given recommendations on increasing the number of consumers of transport infrastructure, establishing privileges or preferential tariffs for socially vulnerable segments of the population and identifying sources for covering these costs. Furthermore, the results of the study create the basis for the formation of specific theoretical and methodological foundations aimed at the development of transport services in the Republic of Uzbekistan.

The size of the territory of the Russian Federation presupposes the existence and systematic implementation of a long-term program for the country’s spatial development, the main element of which is the transport infrastructure. The reorganization of the authorities performing the functions of managing the activities in the field of road transport and road facilities, and the development of strategies for the development of this sector was completed only in the first decade of the 21st century. The total length of transport routes is 1.7 million km, more than 90% of which are roads, which determines the importance of road transport and the development of road transport infrastructure. Automobile transport provides not only economic tasks (transports 68% of cargo), but also solves social issues: it increases the mobility of the population, ensures an increase in well-being (due to the creation of jobs), determines the level of quality of life, ensures territorial accessibility to recreational and healthcare facilities, culture, etc. Nowadays, the domestic fleet of passenger cars is almost 50 million units and continues to grow, but the age structure of the vehicle fleet is deteriorating. The main problems necessary for the implementation of the tasks and ensuring road safety are: expansion and modernization of the road network; provision of transport infrastructure with road facilities, in particular, with service stations in sufficient quantity; improving the quality of service for vehicles and a number of others.

Introduction. An analysis of the most well-known agglomeration management models in Russia and abroad has shown that there are no comprehensive solutions in this area yet. The problem of information modeling of control actions on the state and development of the road network of these territorial entities is not well understood and requires further comprehensive research. The purpose of the paper is to formulate the most important principles and methodological approaches for building a modern information system for managing the road infrastructure of urban agglomerations.Methods and models. The designed system based on information modeling technologies of transport interaction processes between corresponding points. The structure of the system presented on the principles of multi-agent project management. The authors identified the types of mathematical models for solving key problems in the framework of design modules by creation of an agglomeration transport framework, ensuring the regulatory requirements of the transport and operational condition of roads and by creation of conditions for the continuous and safe movement of road transport.Results. The architecture of the “Road Network-6D BIM” developed system reflected the relations of two information processes: filling the system with knowledge and forming box solutions using a knowledge bank. The n-D modeling based on three-dimensional projections of structures (3-D) with the addition of digital modeling technologies: calendar terms, resources and financing of objects in the life cycle. The authors tested system elements during the experiment and the implementation of the project for the integrated development of the transport infrastructure of the Omsk agglomeration.Discussion and conclusions. The implementation of the “Road Network-6D BIM” project in the proposed concept makes a definite contribution to solving the problems of managing the road network of the city agglomeration by increasing the level of intellectualization of the tasks at all stages of project management.

The main task in ensuring the appropriate level of organization of traffic on the street and road network of cities is to minimize traffic delays, increase traffic safety, provide transport and pedestrian communication between the planning elements of the city. Problems caused by the deterioration of the street and road network significantly affect the work of the entire transport complex of the city. Significant traffic delays, congestion, characterized by increased travel time, deterioration of transport services, increased pollution of urban environment due to increased emissions and noise, increasing the number of road accidents indicate the inconsistency of the road network of cities to the modern level of motorization. To ensure the required capacity of the elements of the road network, there is a need to create appropriate road conditions, namely the construction of new and reconstruction of existing engineering structures and elements of streets and roads. However, addressing these issues may not always improve the performance of the entire network, as, in parallel with technical measures based on the construction and reconstruction of transport infrastructure, the application of effective traffic management measures to manage traffic in urban areas should be addressed streets. When creating conditions for optimizing the operation of regulated intersections, it is necessary to take into account the technical condition of vehicles, road conditions and the condition of the road surface. One of the main tasks of any traffic organization is to increase the capacity of intersections and reduce vehicle delays, ie the passage of traffic lights with minimal delay. To solve the problem of congestion of the street and road network of the city is to increase the efficiency and use of coordinated management of traffic and pedestrian flows, improving the operation of traffic lights. To implement the introduction of coordinated traffic light regulation, or the so-called green wave, it is necessary to establish the intensity and composition of traffic flows, the capacity of the elements of the road network and the modes of operation of traffic light facilities. The paper considers the results of the study of the impact of coordinated traffic management in the central part of Rivne on reducing traffic delays when passing intersections by vehicles and proposed technical solutions to improve road safety by equipping intersections with additional technical means of traffic control.

Managing the congestion is an old and legitimate claim of the cities. However, in spite of the promising solutions, the use of passenger cars outside the city centers did not decrease. The still hot topic requires a real solution.The goal of the traffic planning and management was to serve the traffic demands but with the increase in traffic, infrastructure development could not keep up, so this goal - theoretically - is not valid anymore. We are in the midst of a paradigm shift: the old goals are obviously not working, but new goals and the tools needed to achieve them have not yet been developed.According to the presented research, the operation of urban-suburban rush hour congestion radically differs from the way we have assumed so far, so a new framework was developed that describes this traffic operation. This framework allows us to look for new and valid management solutions and set new strategic and operational goals. In this paper, it is proposed not to build infrastructure for traffic demands, but to adapt the traffic demands to the infrastructure, by creating the optimal saturated traffic flow. This will prevent negative traffic dynamics and impacts on the network and provide higher quality and a more reliable road network operation. The research results have led us to theoretical questions such as the right of the limitation of the free routing on the road network.

The paper herein presents greenp-median problem (GMP) which uses the adaptive type-2 neural network for the processing of environmental and sociological parameters including costs of logistics operators and demonstrates the influence of these parameters on planning the location for the city logistics terminal (CLT) within the discrete network. CLT shows direct effects on increment of traffic volume especially in urban areas, which further results in negative environmental effects such as air pollution and noise as well as increased number of urban populations suffering from bronchitis, asthma, and similar respiratory infections. By applying the greenp-median model (GMM), negative effects on environment and health in urban areas caused by delivery vehicles may be reduced to minimum. This model creates real possibilities for making the proper investment decisions so as profitable investments may be realized in the field of transport infrastructure. The paper herein also includes testing of GMM in real conditions on four CLT locations in Belgrade City zone.

<div><span>Diesel light-duty-vehicles (LDV) largely exceed the Euro emission standards of nitrogen oxides (NO<sub>x</sub>) in real-world driving conditions. Air quality models at meso- and large-scale resolutions have recently been used to quantify the impact of such an emission excess upon air quality and human health. In this work, we argue that these approaches can significantly underestimate the impact of diesel LDV excess NO<sub>x</sub> emissions upon NO<sub>2</sub> pollution in compact and heavily trafficked cities. We design two modeling scenarios for the study: a business-as-usual scenario where diesel LDV emit NO<sub>x</sub> in excess, and a counterfactual scenario where emissions are compliant with the Euro emission standards. We compare then NO<sub>2</sub> concentrations of the air quality mesoscale model CALIOPE at both 4 km and 1 km resolution with the street-scale model CALIOPE-Urban in Barcelona city (Spain). The EU annual NO<sub>2</sub> limits are repeatedly exceeded in Barcelona where a large share of passenger cars are diesel (65 %). Results show that the street scale model is able to largely represent the observed NO<sub>2</sub> concentration gradients between traffic and background stations in the city in contrast to the mesoscale model. The mesoscale model strongly underestimates the impact of diesel LDV excess NO<sub>x</sub> emissions upon NO<sub>2</sub> pollution both in absolute terms (by 38 to 48 %) and relative terms (by 10 to 35 %). Using the street scale model, we find that diesel LDV excess NO<sub>x</sub> emissions are associated with about 20 % of NO<sub>2</sub> levels in the city, contributing to an increase of citizens exposed to levels above the EU annual NO<sub>2</sub> limits of 15%.</span></div>
