AbstractPassenger ropeways are a promising alternative for the development of public transport infrastructure in large cities. However, the construction of ropeways has a rather high cost and requires taking into account a significant number of restrictions associated with the features of the existing urban development and the placement of urban infrastructure. The main objective of this research is to develop optimization models that minimize the total cost of modular intermediate towers of a discretely variable height and a rope system due to the optimal placement and selection of the height of these towers, taking into account the features of the surface topography and urban development. The proposed modular principle for the construction of intermediate towers also enables the cost of construction to be further reduced. As a specific example, the design of a ropeway in the city of Bryansk, which has a complex terrain, is considered. The developed models are conveniently used at the initial stage of the design of the ropeway to compare the cost of various options for the location of the ropeway route in order to reduce the risk of error when choosing the least expensive option. The calculation results can serve as a guide for a preliminary assessment of the number and height of intermediate towers, their installation locations on the ground and the characteristics of the cable system.

Sustainable development of large cities and megacities is ensured due to coordinated implementation of program activities in priority sectors of the urban economy. The traditional driver of Moscow’s development and the link for such sectors of the economy is the construction complex, which together with the complex of urban economy, carrying out the improvement of the entire city infrastructure, forms a new urban environment and a modern space for life. The implementation of such a multi-component goal has predetermined a new urban development policy of the city, including the complex of works on construction, reconstruction and renovation of capital objects and territories with supporting engineering, social and transport infrastructure, comprehensive improvement of urban spaces, as well as a number of measures for capital repairs of buildings and structures. The article discusses the methodical approaches and the main results of research dedicated to the urban development of the capital.

Large cities still peak the interests of some Indonesian society. Big city development as the center of economic activity is a powerful pull for society, influencing high workforce from both inside and outside of the city, causing a strong current of urbanization. One main problem that always accompanies urban areas development is density population. Urbanization has caused a very rapid explosion in the city population; one implication is the clumping workforce in large Indonesian cities. The high number of people who choose to settle in the city increase the number of both legal and illegal settlements. In the high-density settlement, many houses are not liveable and irregular. The densely populated settlements find many houses unfit for habitation and irregular. The research aims to formulate the sustainability level of Urban communities, Lowokwaru District, Malang City using quantitative method through sustainability level calculation. Jatimulyo Urban Communities is measured by the sustainability criteria of density, diversity, mixed-use, and compactness to formulate the related sustainable urban spatial structure. Interpretation of the calculation results references similar research. The calculation result shows that Jatimulyo Urban Communities is included in the moderate sustainability level, where density is moderate (101.1-200 people/ha), has a moderate building density (20-40 buildings/ha), has a random diversity level (1.0) and an entropy index (0.51), and compactness is near perfect inequality (Gini Coefficient 0.99).

Transport infrastructure of the city affects the cadastral value of real estate. Transport accessibility of real estate affects the investment attractiveness of land. Transport accessibility increases the market value of the property. Modeling changes in the market value of real estate is an urgent task. Increasing the cadastral value of real estate and tax payments forms a model of investment in transport infrastructure. The article describes an example of modeling the increase in the price of land near the Central bridge of the city of Novosibirsk. The construction of the Central bridge is planned in 2019–2022. The new bridge increases the value of real estate. The cost of land increases by 50–100 %. The scheme of location of price zones is made. The increasing coefficients in the range from 1 to 2 are determined. Investors are given information about the increase in the value of land after the construction of the bridge. The payback period of construction projects is calculated.

In the present work the economic feasibility of a project of public infrastructure, the expansion of the subway of the city Potenza, is estimated. The assessment has been developed through the application of the Cost-Benefit Analysis. As is known the advantage of this technique is the ability to express in monetary terms the externalities (positive and negative) generated by the project. In this case, the external cost savings related to the improvement of the mobility in the city have been internalized. The research has shown that the valuation of the externalities can be an effective way to manage the planning of new public transport infrastructure.

For 200 years, the Metro has been carrying out most of the passenger traffic in large cities and metropolitan areas. The metro architecture embodies cultural ideals, historical milestones and the achievements of society in various fields. The metro is the transport frame of the city, participates in the formation of the urban ensemble. Sustainable development of the metro requires a comprehensive study of its architecture, analysis of domestic and foreign analogues: the prerequisites and chronology of metro development, identification of concepts, directions, principles and techniques of the architectural formation of metro objects. A systematic approach to architectural analysis and design of the metro, identifying the importance of the role of an architect allows to determine the prospects and vectors for the development of transport infrastructure, improve the quality and safety of passenger traffic, design energy-efficient, autonomous, economical, aesthetic and ergonomic metro stations. The high rates of modern metro design require the development of measures to preserve the unity of the metro lines and communication with the city space. Systematization and classification of trends in the development of metro architecture in the period from 1823 to 2000 will allow to determine the arsenal of architectural techniques, to develop urban planning approaches to the architectural solution of the stations

The article considers the features of the functional planning structure transformation of North American megalopolises in the context of the construction of inland railways. The subject of inquiry is the territories of the sett lement system formation in North America from the beginning of colonial invasions, where the interests of Great Britain, France and Spain intersected to the current stage of megacities. There is investigated the infl uence of railway transport on the development of megacities in North America. The subject of research is the Canadian Pacifi c Railroad and the US Transcontinental Railroad, which contributed to the countries urbanization and industrialization. The prerequisites for the transformation of suburban areas were the intensity of labor, cultural, household and industrial links between the center and the periphery in the meridional and latitudinal directions, formation of new kind of scientifi c and industrial complexes, multi-nodes, its infl uence on the functional planning structure of suburban areas and outskirts of megacities. The article introduces the concept of “multi-node”. Multi-nodes are multifunctional urban development complexes with transport infrastructure and engineering facilities which form a complex of terminals for goods transshipment and passengers transferring from one kind of transport to another, as well as public spaces integrated into the urban environment, scientifi c and innovative enterprises with full autonomy and communication that provides the megalopolis with energy resources. Multi-node complexes are located closely to each other and form an integral group, most often around the near-airport territories. This group may not have clear planning boundaries in the form of streets, driveways, fences, and so on. The purpose of the research is to study the sequence of the functional and planning structure formation of the city in dynamics. At the initial stage, from the linear structure of the city along the railway to a more complex ray system, and in the future - the formation of the ring type planning structures, that provide switching of traffi c fl ows on all azimuths directions. It is planning to be constructed a theoretical model of interaction between subcentres and multi-nodes in the suburban zones of intracontinental megacities.

In the last decade light rail transit systems have become a popular mode of public transport in many cities around the world to upgrade the existing public transportation network, but also, and perhaps more importantly, to support neoliberal urban development strategies. The paper takes its starting point in the growing critical literature discussing the politics of light rail and related transport infrastructure projects in the context of neoliberalism. The paper uses the case of Aalborg, Denmark, to demonstrate how light rail projects are embedded in particular infrastructure imaginaries, which reflect wider political agendas of promoting urban development and economic growth. In the case of Aalborg, the city’s spatial strategies have played an important role in constructing an imaginary of the city as the region’s ‘growth dynamo’, which in turn have led to a growth-fixated conceptualisation of the city’s spatiality, and contributed to rationalising the need for investments in light rail. The paper argues that light rail projects are first and foremost politically rationalised as important investments for facilitating urban development and supporting entrepreneurial city strategies of urban and economic growth, whilst their social objectives of providing affordable public transportation play a less prominent role in the contemporary imaginary of the city.

The paper considers an algorithm for solving the problem of finding the optimal location of key objects of transport and warehouse infrastructures within the framework of a methodological approach to designing logistics infrastructure in the territory of the region of the countries. The methodological approach includes three stages. At the first stage, areas  are determined where it is advisable to locate key objects of the regional logistics infrastructure. Further, using the models developed by the authors, the linking of warehouse infrastructure objects on the ground has been carried out and, taking into account the designed warehouse network, the optimal dislocation of transport infrastructure objects has been determined.  To find the optimal locations for the objects for regional logistics infrastructure facilities, the authors propose an algorithm that is applicable both for building warehouse and transport infrastructures due to the similarity of the models. The algorithm is based on the method of constructing a sequence of plans. At the initial stage, the final expansion is constructed for the set of plans under consideration. For a given set, a minorant has been determined for the cost function associated with the placement and maintenance of infrastructure facilities, the movement of goods, and the haul of an empty vehicle. After that, an iterative algorithm has been formed that determines the sequence of optima of the minorant on a sequence of nested sets. At the first step, an element of the set of plans has been found that minimizes the minorant, at the next step, the found element is excluded from the set under consideration, and a new optimum is sought on the remaining set for which the minorant takes the minimum value. To eliminate multiple plans, it is advisable to use dynamic programming procedures. The limits of applicability  of the method for constructing a sequence of plans are determined by the ability to construct an extension of the set of plans for placing objects, select a minorant on it, and build an algorithm for ordering optima.

The article notes that modern methodology development of the general plans for large cities do not contribute to the efficiency of the projects; do not satisfy modern challenges and threats in urban development. One of the most important challenges is the process of globalization, when a special role is assigned to the large cities. Cities compete for the attracting investments, modern industrial facilities, and skill creative specialists. The concept of a competitive city is the motto under which the general plans of major foreign cities are developed. The main differences between the domestic and foreign practices of designing cities are given. First of all, they relate to the links between socio-economic and urban planning policies. In the foreign practice, the modern general plans are developed while taking into account the mission of the city and the strategic goals of the city development; as defined in the general Plans or the Strategies of Social and Economic Development. As a part of the modern strategies of social and economic development (2030-2035) of large Russian cities (St. Petersburg, Kazan) the mission of the city, strategic goals and even the conceptual basis of urban policy defines. It creates prerequisites for more effective communication of socio-economic and territorial planning in comparison with the established urban code, which provides for the mapping of the planned objects. The low social validity of general plans is noted. Possible directions for the improving methodological basis of developing general plans based on the attitude to the general plan as an instrument for creating the town-planning prerequisites for the realization of the city's mission and strategic goals are given.
