The article provides an overview of the current state study of one of the most pressing environmental problems of large cities – the problem of noise pollution. Due to the increasing number of cars, industrial machines and mechanisms to date, over 60% of people living in cities, daily exposed to excessive noise. The aim is to study the problem of noise pollution urboecosystem of Lviv and finding effective methods to combat with noise. Identified sources, the main characteristics and ways of dealing with the harmful effects of noise pollution. Established magnitude of noise burden on certain streets and filed a comprehensive assessment of the acoustic load of the city. A performance experiments noise which generated of motor vehicles when driving on different stretches of road near two intersections – st. Franko – Green and Levitsky – Tershakovciv. Near the street. Franko during bilateral traffic and trams bilateral traffic noise performance of road transport accounted 75,7dBA +/– 3.2. By reducing the transport speed to 6–10 km/h performance noise constituted 70,4dBA +/– 2.5. Indicators of noise on the Levitsky street during a stop to road transport and traffic lights at the beginning of the movement consisted 66,8dBA +/– 2.9 and 2.6 +/– 69,8dBA. Indicators of noise on the Tershakovciv street respectively amounted to 63.8 +/– 3.2 dBA and 65.2 +/– 3.3 dBA. Today, the simplest and most common methods of noise control is the discharge of roads, planting green space and installing anti–noise screens.

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.

Due to the acceleration of scientific and technological progress in the word, the level of traffic flows, industrialization, thenumber of automotive and technical equipment of the urban economy has increased, as a result of which people are constantlyexposed to high-intensity noise. However, few people know that, by its effect on the human body, noise is more harmful thanchemical pollution. Constant exposure to noise not only reduces hearing, but also causes other harmful effects – ringing in theears, dizziness, headache, increased fatigue. People working in noisy conditions have an increased level of neuropsychiatricdisorders.The article discusses the algorithm for evaluative mapping of noise pollution in the settlement area, which will ensurebringing the city territory to sanitary standards. The resulting noise map, which should be part of the master plan, captures thecurrent and future state of the noise regime in the city. Accurate noise maps require the analysis of large number of differentnoise sources and, as a result, are very costly, although in most cases only an estimate of the noise loading is required.Therefore, it is advisable to build a hierarchy of noise sources and take into account the most significant. Such the mostsignificant source of noise in settlements, as a rule, is a road network - streets and lanes on which movement of auto transport isallowed. The procedure for creating a geospatial model of noise pollution in the environment of a geographic information systemdescribed in the article includes creating a multibuffer for each noise source, translating the resulting vector image into a rastersurface, superposition of individual object noise rasters, and creating an integrated evaluated map. Formed ways to improve thenoise situation based on the results.

The article discusses the issues and results of the use of statistical modeling (one of the types of simulation modeling, the so-called "Monte Carlo" method), to assess the effectiveness of traffic management on the example of the Timofey Charkov st. and Verkhnetarmanskaya st. intersection, located in the city of Tyumen. The results are based on the length of the vehicle queue and traffic delay time for one car in the scenario of widening the intersection’s carriageway and/or the implementation of the adaptive regulation for traffic flows. The calculations were carried out in the "SmartAdaptive+" program developed by the authors, and designed for a technical and economic assessment of the effectiveness of traffic management measures and the use of adaptive regulation and measures to change the road network nodes configuration.

Every country's vehicular traffic is increasing, growing, and there is terrible traffic congestion at intersections. In the current case, most traffic lights have a fixed light sequence, so green light sequence is to determine with-out taking priority vehicles into account. As a result, priority crews such as police cars, ambulances, fire engines are still unable to perform, get stuck in traffic and come in late, which can result in the loss of valuable property and life, which does happen on occasion. The green light sequence is evaluated given the current state of traffic, without taking into account the existence of emergency vehicles. Our aim to this paper is to present a mechanism for scheduling emergency vehicles. It is provided to important such as access control protocol to convey emergency vehicle information to the Traffic Management Center (TMC) with time delay and to all alerts while using GPS techniques for acquiring emergency vehicle information. Only then is the emergency vehicle quickly dispatched, and the destination is reached on time. It would be helpful in the future for the prominence of casual vehicles.

The objective of the article is to develop a system of principles and methods aimed at improving management of transport flows on the street and road network of a large city with traffic lights regulation. The suggested methodology is based on the methods used in Russia and abroad to improve road traffic safety and quality, results of a survey of experts in the field of road design and traffic management, monitoring at regulated crossings, and analysis of road accidents in the city of Volgograd. The primary customer property of a regulated crossing is road safety. Elimination of causes of road traffic accidents associated with road traffic, structural geometric, signalling, and technical conditions is the most important task regarding a regulated crossing. Enhancing road traffic quality at low levels of network load supposed considering demand for transportation, increase in travel comfort, coordination, and flexibility of traffic lights operation. High degree of network load supposes that more attention is paid to traffic capacity of the street and road network elements, restrained access of vehicles to areas of greater congestion, increased duration of a green light cycle (for more than 120 seconds, if this does not affect traffic safety and network congestion degree).

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.

Expansion of a road network has often been observed to cause more congestion and has led researchers to the formulation of traffic paradoxes such as the Pigou–Downs and the Braess paradoxes. In this paper, we present an application of advanced traffic signal control (ATSC) to overcome the Pigou–Downs paradox. Port Louis, the capital city of Mauritius is used to investigate the effect of using a harbor bridge to by-pass the city center. Using traffic cellular automata (TCA) simulations it has been shown how, if traffic is only gradually deviated along the by-pass, an overall longer travel time and decreased flux would result. By making use of ATSC, which involves traffic lights that sense the number of vehicles accumulated in the queue, better travel times and fluxes are achieved.
