The article discusses development of a system of transport and interchange hubs (TIH). The need to create TIHs is due to an opportunity to increase efficiency of passenger flows in the urban public transport system, to reduce travel time for passengers, to ensure comfortable and safe conditions for transfer, and to improve quality of service to the population.  The objective of the research is to develop methods that allow solving the problem of optimal selection of TIH locations in any city according to the economic criterion and the criterion of the average travel time using the methods of mathematical modelling. The technique comprises search for optimal travel routes in the city and identification of effective interchange hubs using the developed software product called «Efficient transfers». Efficient transfer hubs with maximum passenger traffic are candidates for TIH locations. The work describes calculations made according the proposed methods and optimal options for location of this in the city of Samara considering limited funds, reduction in travel time and in the number of passengers using these TIHs. The research also resulted in obtaining the dependence of reduction in the average time of an urban trip on the number of TIHs.

Abstract Due to the increased tendency to use private transport in urban areas of Manizales and Villamaría municipalities, it is intended to include alternative modes of transport that are more time-efficient and environmentally sustainable to improve the inhabitants’ quality of life. This article aims to analyse the inclusion impact of a sustainable public transport system, such as a new cableway line in the city connecting the Central Business District (CBD) with Ciudadela del Norte district, measuring overall average accessibility for the current and future scenario. This establishes the average travel time and the savings in terms of time shown as a percentage that these modes of transport would create in the population displacement and also which inhabitants are the most likely to benefit.

The present paper investigates the characteristics and best construction strategies of smart cities around the world, as well as the determining factors of the satisfaction of the quality of life and the importance of the value of environmental sustainability. A case study of the city of Kalampaka and its residents was examined. The survey was conducted between July 2016 and August 2016. The selection of the sample was done by using the method of simple selection and includes a random sample of N=150 individuals. Statistical analysis showed that resident’s knowledge about smart cities was fairly good (48% of sample knew the phrase “smart cities”). Furthermore, they believe that the appearance of the city of Kalampaka needs improvement (75% of sample is disappointed with the current appearance of the city). Regression analysis showed that the value of environmental sustainability is greatly influenced by the energy saving, as well as, innovation has an impact on the level of quality of life. Older people seem to be satisfied with administration’s efforts.

Studies show that Tehran is one of the most polluted cities in the world. This pollution is more due to the traffic of cars. According to statistics, Tehran only had 3 days of clean air in 2012 and 2013. The consumption of low-grade petroleum products by non-standard vehicles manufactured with old technol- ogy has caused air pollution to the city in the absence of an efficient public transport system as well as inefficient management. The results suggest that transition from this dilemma is possible through efficient laws, proper man- agement, the use of world-wide knowledge and culture and general education from the basic levels. Obviously, solving this problem will directly affect the quality of life of citizens, and its effects can be seen in the economic, health, environmental and social spheres. The indirect effects of the crisis can be predicted in economic growth and development, and even in the promotion of national security (at a high level).

The article discusses the main activities of state authorities, labor collectives of transport enterprises in Western Siberia to improve the operation of urban public transport in the region during the eighth five-year plan (1966-1970). During the study period, the increase in the level of transport services for urban residents was directly related to measures to develop and strengthen the material and technical base of passenger transport enterprises, technical re-equipment of automobile and tram rolling stock, and construction of a new type of public transport in Western Siberia – the urban trolleybus. The author comes to the conclusion that during the eighth five-year plan, urban public transport enterprises in the region received significant material and technical development, which became the basis for increasing the volume of passenger traffic and improving the quality of transport services for the urban population of the West Siberian region

The article is devoted to the establishment of information support to determine the patterns of changing the function of gravitation of employees of the urban-service enterprises. It has been established that the development of urban transport systems is impossible without the use of information technology to predict the parameters of the formation and absorption of passenger traffic. The design of urban transport systems cannot be achieved without assessing the impact of traffic improvement measures on changes in traffic and passenger flows. The main parameter by which it is possible to predict the choice of places of gravity by the inhabitants of cities is the function of gravitation between different areas of the city. The formalized functions of the gravitation of urban dwellers are not differentiated by the social composition of the population of cities. In addition, they use only travel time between areas of the city as an independent variable. The article proposes the formalization of the gravitation function of employees of the urban service enterprises using the parameters of the urban transport system, areas of departure and arrival, as well as the cost of movement. A special questionnaire has been developed to obtain the original information. A natural survey was carried out using it. As a result of the processing of survey data using correlation and regression analysis methods, the degree of influence of the studied factors on the value of the gravitation function of employees of urban service enterprises was revealed. Analysis of the correlation values obtained showed that the most significant impact on the value of the gravitation function of employees of urban services is the ratio of the cost of movement between districts and average wages in the city. The least impact is the distance from the area of residence to the place of application of work, the ratio of the cost of one square meter of housing in the area of residence and the average salary in the city, the ratio of the cost of one square meter of housing in the area of employment application and the average salary in the city. However, the compatible influence of all factors can change the level of influence of each factor and its combinations. In addition, it is advisable to take into account the technical and operational performance of urban passenger transport routes and individual transport routes.

The article discusses the modern problems of green building. The duality of the greening problem in large cities is noted: on the one hand, this is one of the factors of conflict, on the other hand, the factor of the quality of life, creativity of the city, and its image level. The selection of factors for the analysis was carried out taking into account the research of Russian and foreign scientists and the possibility of obtaining reliable statistics. The study was conducted according to the landscaping of the districts of St. Petersburg. As a result of the study, clustering of St. Petersburg districts was carried out according to greenery indicators, the level of green construction in each of the considered territories of the city was estimated. A paired analysis of indicators made it possible to identify the most problematic areas of the city, to conduct a comparative assessment of the districts according to the level of greenery and their sufficiency to create a comfortable environment

The center of activities of Santiago de Chile has been continuously evolving towards the eastern part of the city, where the most affluent residents live. This paper characterizes the direction and magnitude of this evolution through an indicator stating how much the built surface area for service purposes grows in different areas in the city. To identify the impact of this evolution, we compare residents’ travel-time distributions from different sectors in the city to the central area. This travel-time comparison is focused on the sectors where informal settlements were massively eradicated between 1978–1985 and those areas where the settlements were relocated. This analysis show that this policy and the consequent evolution of the city were detrimental to the affected families, significantly increasing average travel time to the extended center of the city and inequality among different socioeconomic groups in the city. Although the phenomenon is quite visible to everyone, it has not received any policy reaction from the authority. These findings suggest that middle and low-income sectors would benefit if policies driving the evolution of the center of activities towards them were implemented.

The selection of an optimal urban public transport system is prepared by a feeding-back planning process based on systems analysis. The decision situations are presented graphically, they define a plausible area of value judgements and insert into the figure indifference lines for each pair of alternative systems. The scheduling problem is handled by applying utility profile theory and zero–one optimization technique. By means of a particular formulation of variables and constraints, horizontal and vertical interdependencies between investment alternatives can be integrated.

Reducing passenger flow through highly frequented bottlenecks in public transportation networks is a well-known urban planning problem. This issue has become even more relevant since the outbreak of the SARS-CoV-2 pandemic and the necessity for minimum distances between passengers. We propose an approach that allows to dynamically navigate passengers around dangerously crowded stations to better distribute the passenger load across an entire urban public transport network. This is achieved through the introduction of new constraints into routing requests, that enable the avoidance of specific nodes in a network. These requests consider walks, bikes, metros, subways, trams and buses as possible modes of transportation. An implementation of the approach is provided in cooperation with the Munich Travel Corporation (MVG) for the city of Munich, to simulate the effects on a real city’s urban traffic flow. Among other factors, the impact on the travel time was simulated given that the two major exchange points in the network were to be avoided. With an increase from 26.5 to 26.8 minutes on the average travel time, the simulation suggests that the time penalty might be worth the safety benefits.
