The problems of improving the quality of public urban transport services, environmental protection, and public health in large cities and megacities have taken the leading place among the issues on the agenda of public administration bodies, as well as of non-governmental and international organisations.This context determined the study on the significance, modern conditions, problems, and development outlook regarding the urban public transport in Yerevan.Important part of the population of the Republic of Armenia lives in the city of Yerevan. Main economic activity of the Republic, as well as urban and private transport facilities are most concentrated in the capital city. The total number of vehicles circulating in the city on working days exceeds 300 thousand units.Urban public transport of Yerevan plays an important role in ensuring the normal life of residents and guests of the city. At the same time, several serious socio-economic problems are associated with transport, which are aggravating while the economy develops and the volume of cargo, passenger transportation and motorization of the city grows. Such problems, first, include the growth of the number of road traffic accidents, then, serious environmental degradation in the areas adjacent to the highways and in other districts of the city.In recent years, it has become obvious that the solution to those problems goes beyond the competence and responsibility of the city hall or of any single ministry and requires focusing the efforts of the number of government bodies and of the public at large.The objective of the study is to identify the main factors affecting the efficiency and safety of urban public transportation, as well as the impact of road traffic on the environment in Yerevan.Their identification will improve the quality of transport services and transportation safety, as well as reliability of vehicles and of their service properties, reduce their environmental impact, and develop a unified integrated effective and viable system of measures towards a comprehensive and effective solution of transport problems of public urban transport.

The article considers the main approaches to the analysis of motivation in the management of transport behavior of the inhabitants of megacities. A number of surveys of urban residents confirm that the level of traffic is one of the main problems facing society. Concepts for managing the demand for passenger traffic in the world's cities are considered. The goals, objectives and measures of the concept of traffic demand management are defined and structured. Cities around the world are looking for opportunities to switch drivers from private cars to public transport. Psychological determinants (attitudes, acceptance, interests), which are important but hidden variables in the analysis of transport behavior of megacities, are substantiated. Among them, the content is completely unexpected, those that are not considered in domestic scientific sources to assess the quality of urban transport (and are just beginning to appear in foreign studies). Personal factors of transport behavior (re-choice of route) are considered from the standpoint of a new scientific trend - behavioral economics. Improving the quality of services also determines high ratings of satisfaction and consumer value. Consumer value suffered mainly from the sacrifices of passengers. Based on the findings, a number of management measures were proposed. The TDM concept is one way to manage the demand for transportation. Managing demand for transportation is not a panacea, but it helps solve transportation problems in the city. An analysis of the availability of opportunities to motivate people to use public transport more often (with an acceptable value of the perceived quality of travel). Among the conditions and motives for the transition to the use of public transport to replace the car should be noted: the strength of the impact on the person; unconditional quality of providing basic and additional services when traveling in the city; creation of a person's stable personal beliefs (environmental, sense of their own city, etc.); providing transport information in real time. Fear of loss of time, increased costs, accidents, violation of private space (crowding) is also a strong motive for changing transport behavior.

Public transportation is one of the sustainable form of transportation which provides mobility options for the people. The public transport services are very basic need of people’s lives, especially in developing world. It is the basic means for mobility of a large percent of people and hence it is the driving force of economic and social life. Quality of service, characterized by the Level-of-Service (LoS) is one of the major factors determining the demand for public transport. This study tries to determine the city-wide Level-of-Service provided by the public transport system using the service level benchmarks as a case study of Trivandrum city. The indicators for determining the Level-of-Service used in the study are presence of organized public transport system, availability or extend of public transport supply, service coverage, average waiting time, level of comfort in public transport and the fleet availability. This approach can be used to determine the LoS at the city-level and thus provides a measure for identifying the public transport quality of an urban area.

The subject of the study is the formulation of strategic measures to improve the quality of public transport services. The goal is to justify a set of strategic measures aimed at improving the quality of public transport services. To achieve this goal, the following research objectives have been identified and solved: to establish the specifics and principles of effective strategic planning for urban transport services provision; to identify the features of urban transport services system; to identify the main measures for urban public transport services development, in particular, for the city of Kyiv. To achieve the goal of the study, a set of system theory methodologies has been selected. In modern science, this approach is considered to be the most productive and capable of providing a high degree of verification of the results obtained. As a result of the study: 1) a complex of strategic measures is substantiated, aimed at improving the quality of public transport services, namely: optimization of modal transportation; integration of modal transportation; optimization of road space; increasing the bus fleet; improving bus design and increasing the comfort in passenger compartments; selection of fare forms; development of information systems of interaction; compliance with the Traffic Laws and passenger transportation rules; increase of internal efficiency of transport operators’ activities; use of information technologies; increase of transport operators’ incomes; 2) the specifics and principles of effective strategic planning for urban transport services provision are established. They consist in applying an iterative approach to strategic planning. Its advantages are due to simultaneous execution of any strategic planning work (from writing the following elements of the strategic plan to the fulfilment of its objectives) with continuous analysis of results obtained, which makes it possible to adjust the works according to the changing environment conditions; 3) the features of the urban transport service systems are revealed, namely: urban public transport systems are complex open dynamic socio-economic systems. We consider multimodality of external environments, multifactoriality of external influences, presence of internal imbalances in systems as one of the main reasons for their unsatisfactory state. Therefore, a multifaceted approach is needed, which takes into account the maximum number of factors and combines a range of measures to improve the quality of urban passenger transportation; 4) the main measures for the development of urban public transport services, in particular, for the city of Kyiv, are identified, namely: ensuring multimodal public access to public transport stations and public places; organization of information and communication interaction between all elements of the passenger transportation system; use of various forms of urban public transport fare; mathematical modelling of integration interaction of different types of public transport.

This comparative study analyzes the impact of the COVID-19 pandemic on motorized mobility in eight large cities of five Latin American countries. Public institutions and private organizations have made public data available for a better understanding of the contagion process of the pandemic, its impact, and the effectiveness of the implemented health control measures. In this research, data from the IDB Invest Dashboard were used for traffic congestion as well as data from the Moovit© public transport platform. For the daily cases of COVID-19 contagion, those published by Johns Hopkins Hospital University were used. The analysis period corresponds from 9 March to 30 September 2020, approximately seven months. For each city, a descriptive statistical analysis of the loss and subsequent recovery of motorized mobility was carried out, evaluated in terms of traffic congestion and urban transport through the corresponding regression models. The recovery of traffic congestion occurs earlier and faster than that of urban transport since the latter depends on the control measures imposed in each city. Public transportation does not appear to have been a determining factor in the spread of the pandemic in Latin American cities.

This study assesses changes in mobility behaviour in the City of Barcelona due the COVID‐19pandemic and its impact on air pollution and GHG emissions. Urban transport is an important sourceof global greenhouse gas (GHG) emissions. Improving urban mobility patterns is therefore crucial formitigating climate change. This study combines quantitative survey data and official governmentdata with in‐depth interviews with public administration officials of the City. Data illustrates thatBarcelona has experienced an unprecedented reduction in mobility during the lockdown (a 90%drop) and mobility remained at comparatively low levels throughout the year 2020. Most remarkableis the decrease in the use of public transport in 2020 compared to pre‐pandemic levels, whereas roadtraffic has decreased to a lesser extent and cycling surged at times to levels up to 60% higher thanpre‐pandemic levels. These changes in mobility have led to a radical and historic reduction in airpollution, with NO2 and PM10 concentration complying with WHO guidelines in 2020. Reductions inGHG emissions for Barcelona’s transport sector are estimated at almost 250.000 t CO2eq in 2020 (7%of the City’s overall annual emissions). The study derives policy implications aimed at achieving along‐term shift towards climate‐friendlier, low‐emission transport in Barcelona, namely how torecover lost demand in public transport and seize the opportunity that the crisis brings for reform byfurther reducing road traffic and establishing a 'cycling culture' in Barcelona, as already achieved inother European cities.

A properly functioning public transport is one of the most important components of urban mobility for the population. Due to spatial inhomogeneity and overall socio-economic differences within a city, there are often considerable disproportions in the quality of transport services within its districts. Also, the city of Krakow is no exception in this case. For a comparison of public transport accessibility in 18 Krakow districts, 7 major quantitative and 5 minor indicators were created. These indicators include the most important characteristics of transport services such as accessibility, frequency, connectivity of connections, and ratios of tram public transport subsystem. The resulting values give a fairly comprehensive picture of the quality of the transport services. Overall higher values for most indicators occur in the central districts of the city. However, due to the complexity of the observed characteristics, it is possible to discover significant differences in the structure of individual indicators. Peripheral districts reach higher amplitudes, which means that in some aspect they have even better transport services than the city center. Yet, at the same time, we also find opposite extremes here, highly below-average values for most other indicators. A detailed analysis of the results provides a unique perspective on the disparities among districts. It can also serve for specific identification of strengths and weaknesses of transport services and its possible optimization.

In rentier countries around the Gulf, a paradigm shift is certainly happening. Gulf States resorted to branding strategies which would secure a global recognition for their cities. The paper analyzes the effectiveness of tools used in Doha, the capital city of Qatar to create its own identity within the Gulf States and the rest of the Middle East. The analyzed tools will include City Uniqueness, Quality of Public Spaces, Signature Architecture, Events, Festivals, Cultural Tourism and Facilities. One of the main strategies used in Doha to articulate its brand is enhancing the ability of the city to host global Events, Festivals, and international sports. Competitions and cultural Carnivals. The research illustrates the use of Interesting Architecture, Cultural Facilities, Unique streets, Public parks, City natural and man-made Uniqueness as a City Marketing and Positive Branding Tools. The paper investigates crucial questions including the impact of the digital paradigm on the competitiveness of cities? How to regionally and globally market a city? What are the sustainable and resilient strategies for branding contemporary city? The paper also articulates a model for the case of Doha city banding and marketing which is based on a balanced approach. Such an approach would consider traditional assets including history and heritage. Also, it will include contemporary and innovative assets resulted from the last decade unprecedented investments in the sectors of education, research, culture and knowledge. Hence, the paper suggests a more holistic approach to city branding which would balance between social equity, economic prospertiy and ecological intergrity.

As a result of the analysis, it was revealed that social networks (Vkontakte, Facebook), thematic communities in microblogging networks (Twitter), resources for travelers (TripAdvisor), transport portals (Autostrada) are a source of up-to-date and operational information about the traffic situation, the quality of transport services and passenger satisfaction with the quality of levels of transport services. However, the existing transport monitoring systems do not contain software tools capable of collecting and analyzing traffic information located in the Internet environment. This paper discusses the task of building a system for automatically retrieving and classifying road traffic information from transport Internet portals and testing the developed system for analyzing the transport networks of Crimea and the city of Sevastopol. To solve this problem, an analysis of open source libraries for thematic data collection and analysis was carried out. An algorithm for extracting and analyzing texts has been developed. A crawler was developed using the Scrapy package in Python3, and user feedback from the portal http://autostrada.info/ru was collected on the state of the transport system of Crimea and the city of Sevastopol. For texts lemmatization and vector text transformation, the tf, idf, tf-idf methods and their implementation in the Scikit-Learn library were considered: CountVectorizer and TF-IDF Vectorizer. For word processing, Bag-of-Words and n-gram methods were considered. During the development of the classifier model, the naive Bayes algorithm (MultinomialNB) and the linear classifier model with optimization of the stochastic gradient descent (SGDClassifier) were used. As a training sample, a corpus of 225,000 labeled texts from the Twitter resource was used. The classifier was trained, during which the cross-validation strategy and the ShuffleSplit method were used. Testing and comparison of the results of the pitch classification were carried out. According to the results of validation, the linear model with the n-gram scheme [1, 3] and the vectorizer TF-IDF turned out to be the best. During the approbation of the developed system, the collection and analysis of reviews related to the quality of transport networks of the Republic of Crimea and the city of Sevastopol were conducted. Conclusions are drawn and prospects for further functional development of the developed tools are defined.
