The chapter proposes the correction of the concept of “smart city.” It is substantiated that the specificity of the redistribution of the population and economic resources to the major cities of Russia, mainly to regional centers, requires the modification of the concept of “smart city.” In accordance with this concept, a number of principles are proposed, among which the most important are the principles: integration, metabolism, architectural quality of the urban environment. The most important functional goals are defined: the creation of a new production structure, formation of a modern transport and logistics infrastructure, modernization of the road-street network, development and modernization of the rolling stock of urban transport, development and modernization of communal infrastructure, provision of safe and comfortable living conditions for citizens, improvement of the ecological condition of the urban district, improvement of the state of objects of cultural heritage and improvement of the urban district. Three levels are singled out, each of which requires solutions.

The development of urban transport in recent years has become one of the most important issues related to improving the quality of life in Polish cities. Excessive pollution in the form of greenhouse gases and other harmful substances from buses affects people’s health as does the excessive noise. This article analysed the measures being taken to reduce emissions, and the results showed that it is possible to reduce CO2 emissions by more than 28 thousand megagrams (Mg) per annum. Policymakers in Poland should consider limiting electricity generation through coal combustion and recognize, at least temporarily, CNG/LNG-powered buses as low-carbon rolling stock and co-finance their purchase and the necessary infrastructure.

Nowadays, the world’s leading cities are focused on the Smart City concept, due to the widespreading of innovations that enhance quality of life. The need for sustainable development for the harmonious prolongation of the humanity existence raises attention to attempts for improving the economic, social and environmental conditions. Among the modes of transport, the most harmonious in the modern city, which strives for sustainable development, is the tramway. The experience of the tramway renaissance during the last decades indicates that it is not only a mode of transport but also a positive impact on the urban space and community. In the context of Ukraine’s integration into the European Community, it is important to analyse the experience of cities that have been successful in implementing urban transport innovations. In the article, we compare the cities of Kyiv and Budapest to find spatial patterns that should be obeyed for the sustainable development of a post-socialist city based on smart solutions.

Introduction. Recently, in large and medium-sized cities, the increase in traffic has been exacerbated by the growth of motorization and the lack of development of the road network. Increasing vehicle traffic to a critical level leads to overcapacity of the arteries and, as a consequence, increases the level of delay. Public urban mass passenger transport is one of the most vulnerable groups in this regard. In order to unload the city’s street network, it is necessary to reduce the level of road traffic. One of the effective measures to deal with this problem is to increase the attractiveness of urban mass passenger transport, i.e. to ensure an adequate level of service for passengers including high speed, which can be increased by giving priority to bus traffic. One of the prospects for prioritizing public urban transport is the development of individual lanes or streets for urban rolling stock only. Due to the lack of criteria for the allocation of separate lanes for urban rolling stock, they have begun to appear in the vast majority on the main streets of the city. There are a large number of urban highways used for the operation of only one public transport route with dedicated lanes on them. The need for such arrangements is questionable. It is therefore necessary to formulate the criteria that justify the need for a separate urban passenger lane on a given stretch of the city network. Thus, the purpose of this work is to identify patterns between traffic parameters and the parameters of the urban public passenger transport programme, which will determine the criteria for the need for a separate lane for urban land transport on each individual stretch of the network.Materials and methods. This article deals with the method of determining the need for a separate lane for public urban passenger transport on a given stretch of the road network. In order to improve the quality of the transport of passengers, a mathematical model has been developed, based on such indicators as the level of traffic delay and the share of passenger traffic in the total flow of participants. Results. The necessary conditions have been laid down the strict implementation of which determines the need to ensure the priority of urban mass public passenger transport on the section of the city’s street network under consideration.Discussion and conclusion. The dependencies obtained make it possible to identify the need to ensure the priority of urban transport.

Transit stations are generally well known as nodes of spaces where percentage of people walking are relatively high. The issue is do more planning is actually given to create walkability. Creating walking led transit stations involves planning of walking distance, providing facilities like pathways, toilets, seating and lighting. On the other hand, creating walking led transit station for women uncover a new epitome. Walking becomes one of the most important forms of mobility for women in developing countries nowadays. Encouraging women to use public transportation is not just about another effort to promote the use of public transportation but also another great endeavour to reduce numbers of traffic on the road. This also means, creating an effort to control accidents rate, reducing carbon emission, improving health and eventually, developing the quality of life. Hence, in this paper, we sought first to find out the factors that motivate women to walk at transit stations in Malaysia. A questionnaire survey with 562 female user of Light Railway Transit (LRT) was conducted at LRT stations along Kelana Jaya Line. Both built and non-built environment characteristics, particularly distance, safety and facilities were found as factors that are consistently associated with women walkability. With these findings, the paper highlights the criteria  which are needed to create and make betterment of transit stations not just for women but also for walkability in general.

Subject. The article considers functioning and development of process flows of transportation and logistics system of a smart city. Objectives. The study identifies factors and dependencies of the quality of human life on the organization and management of stream processes. Methods. I perform a comparative analysis of previous studies, taking into account the uniquely designed results, and the econometric analysis. Results. The study builds multiple regression models that are associated with stream processes, highlights interdependent indicators of temporary traffic and pollution that affect the indicator of life quality. However, the identified congestion indicator enables to predict the time spent in traffic jams per year for all participants of stream processes. Conclusions. The introduction of modern intelligent transportation systems as a component of the transportation and logistics system of a smart city does not fully solve the problems of congestion in cities at the current rate of urbanization and motorization. A viable solution is to develop cooperative and autonomous intelligent transportation systems based on the logistics approach. This will ensure control over congestion, the reduction of which will contribute to improving the life quality of people in urban areas.

Представлены результаты внедрения в хирургическую практику урологического отделения Дорожной клинической больницы г. Ярославль биполярной техники трансуретральной резекции (БТУР) и энуклеации простаты (ТУЭБ) для лечения доброкачественной гиперплазии предстательной железы (ДГПЖ) средних и больших размеров. В сравнительное исследование включено 164 пациента, разделенных по методам операции на 2 основные группы (ТУЭБ - 33 человека, БТУР - 49) и 2 контрольные (открытая простатэктомия - ОПЭ - 38 и монополярная ТУР - 44). Для новых эндоскопических методов установлено значимое снижение объема кровопотери, частоты геморрагических осложнений, сроков послеоперационной катетеризации и госпитализации. Для количественной оценки различий средних и относительных показателей использо-вали непараметрический критерий Манна-Уитни, оценка качественных признаков проводилась с применением критерия Пирсона (χ2), уровень значимости различий для исследования выбран р ≤ 0,05. Анализ послеоперационной динамики клинических показателей в среднесрочной перспективе показал сходную радикальность и эффектив-ность сравниваемых методов. Установленные меньшая инвазивность, большая безопасность и лучшая переносимость биполярных эндоскопических операций демонстрируют перспективность их внедрения взамен бывших стандартных хирургических методов, что позволит повысить качество оперативного лечения и сократить затраты стационара. The results of the introduction into surgical practice of the urological Department of the road clinical hospital of Yaroslavl bipolar technique of transurethral resection (BTTR) and enucleation of the prostate (EOTP) for the treatment of benign prostatic hyperplasia (BPH) of medium and large sizes are presented. The comparative study included 164 patients, divided by the methods of surgery into 2 main groups (EOTP - 33 people, BTTR - 49) and 2 control (open prostatectomy - OPE - 38 and monopolar TTR - 44). For new endoscopic methods, a significant reduction in the volume of blood loss, the frequency of hemorrhagic complications, the timing of postoperative catheterization and hospitalization was established. Nonparametric Mann-Whitney test was used to quantify the differences in mean and relative indicators, qualitative characteristics were evaluated using Pearson test (χ2), the significance level of the differences for the study was chosen p ≤ 0.05. Analysis of postoperative dynamics of clinical parameters in the medium term showed similar radicality and effectiveness of the compared methods. The lower invasiveness, greater safety and better tolerability of bipolar endoscopic operations demonstrate the prospects of their implementation instead of the former standard surgical methods, which will improve the quality of surgical treatment and reduce the costs of the hospital.
