The evaluation of the social impacts of transport policies is attracting growing attention in recent years. Yet, this literature is still predominately focused on developed countries. The goal of this research is to investigate how investments in public transport networks can reshape social and geographical inequalities in access to opportunities in a developing country, using the city of Rio de Janeiro (Brazil) as a case study. Recent mega-events, including the 2014 Football World Cup and the 2016 Olympic Games, have triggered substantial investment in the city’s transport system. More recently, though, bus services in Rio have been rationalized and reduced as a response to a fiscal crisis and a drop in passenger demand, giving a unique opportunity to look at the distributional effects this cycle of investment and disinvestment have had on peoples’ access to educational and employment opportunities. Based on a before-and-after comparison of Rio’s public transport network, this study uses a spatial regression model and cluster analysis to estimate how accessibility gains vary across different income groups and areas of the city between April 2014 and March 2017. The results show that recent cuts in service levels have offset the potential benefits of newly added public transport infrastructure in Rio. Average access by public transport to jobs and public high-schools decreased approximately 4% and 6% in the period, respectively. Nonetheless, wealthier areas had on average small but statistically significant higher gains in access to schools and job opportunities than poorer areas. These findings suggest that, contrary to the official discourses of transport legacy, recent transport policies in Rio have exacerbated rather than reduced socio-spatial inequalities in access to opportunities. These results also suggest that future research should consider how the modifiable areal unit problem (MAUP) can influence the equity assessment of transport projects.

Permissible Dose

The available methodological approaches to assessing the noise dose characterize the multiplicity of exceeding the permissible dose, but do not reflect the transition to the weighted average equivalent level for the tasks of assessment of health risk to population living under exposure to the noise factor. Within the framework of the study, there were proposed methodical approaches which allow the transition from the multiplicity of exceedences of an individual noise dose to the calculation of the weighted average daily noise equivalent (Lden) by taking into account the number and duration of noise events. The proposed method allows the assessment and prognosis of the risks of health disorders using the approved method from the impact of noise factor (MR 2.1.10.0059-12 [9]). Testing methodological approaches using the example of children's pre-school institutions in the city of Perm made it possible to establish a daily noise dose with an assessment of the impact of each factor and determine the possible risks to health of children attending preschool institutions near transport infrastructure facilities. According to the results of this study, it was found that self-induced noise makes the main contribution to the daily noise dose.

The research paper presents theoretical and practical aspects of differentiation of territories according to the level of transport infrastructure development. The purpose of the research is to develop a formalized approach to territorial differentiation according to the level of transport infrastructure development on the example of Ukrainian regions. The issues with the term of "transport infrastructure" are defined. Classical methodological approaches to transport infrastructure level of development assessment are described. The essence of the concept of "differentiation" and its meaning in the transport industry are revealed. The coefficients for assessing the provision of regions with transport infrastructure, transport network density coefficient and the assessment of transport network safety indicator are considered. On the basis of the considered coefficients and initial statistical data, the analysis of regions of Ukraine, based on a level of development of a transport infrastructure, was conducted. The inequality of transport infrastructure level of development (even within one country) is caused due to both objective (geographical location, resource potential) and subjective reasons (efficient use of resources, effectiveness of regional management). An integrated assessment in order to solve this task was formed. It is based on the apparatus of the methodology of decision-making in conditions of uncertainty. For the practical demonstration, the regions of Ukraine were differentiated, according to the level of transport infrastructure development. During the evaluation, it is possible to determine the factor with the greatest impact on the overall result by region. Improving the quantitative indicators that form the most influential qualitative assessment would lead to an increasement of the overall assessment. Thus, using the developed algorithm, it becomes possible to optimize the management of transport infrastructure development of a particular territory.

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.

Soft ground improvement to provide stable foundations for infrastructure is national priority for most countries. Weak soil may initiate instability to foundations reducing their lifespan, which necessitates the adoption of a suitable soil stabilization method. Amongst various soil stabilization techniques, using appropriate admixtures is quite popular. The present study aims to investigate the suitability of bagasse ash and stone dust as the admixtures for stabilizing soft clay, in terms of compaction and penetration characteristics. The studies were conducted by means of a series of laboratory experimentations with standard Proctor compaction and CBR tests. From the test results it was observed that adding bagasse ash and stone dust significantly upgraded the compaction and penetration properties, specifically the values of optimum moisture content, maximum dry density and CBR. Comparison of test results with available data on similar experiments conducted by other researchers were also performed. Lastly, a study on the cost effectiveness for transport embankment construction with the treated soils, based on local site conditions in the study area of Assam, India, was carried out. The results are analyzed and interpreted, and the relevant conclusions are drawn therefrom. The limitations and recommendations for future research are also included. Doi: 10.28991/cej-2021-03091771 Full Text: PDF

Effective transport infrastructure development is known to be one of the key aspects of sustainable development of modern city environment. Creation of transport hubs is expected to make a contribution to the improvement of transport infrastructure. Some practical examples of implementing of hubs in Moscow were considered. The article proves that the creation of the transport hubs, is capable to contribute to the sustainable urban development: to provide high social-and-economic living standards for inhabitants, to make changes of different types of transport fast and convenient, to eliminate “poor points” in the transport infrastructure, to reduce stoppers in the city, to provide inhabitants with the necessary number of parking spaces and also to become an additional source of income both for the city, and for commercial structures. It also will be able to increase the investment attractiveness and investment activity of the area in general. However, the author criticizes the current approach to the organization of investments into the hub projects. The public-and-private-partnership in its broad sense would allow dividing expenses, risks and profit within the project, and at the same time keeps the municipal property for the facility. Meanwhile the use of concession does not allow providing the maximum transport project efficiency.

The problem of congestion is one of the key issues faced by cities. There are many ways to improve the functioning of the city’s road infrastructure, enabling reduction of the congestion level. The proper level of transport infrastructure development is indispensable for the proper functioning of transport, which determines the effective transport service of residents, and thus improves the broadly understood quality of life. The article focuses on the effects possible to achieve thanks to the implementa-tion of investments in road infrastructure with particular emphasis on city bypasses. The example of Starogard Gdański presents the problem of eliminating transit traffic from city centers through the construction of a bypass. The article discusses the results of the experiment carried out to estimate the benefits of the construction of the Starogard Gdański bypass. As part of the experiment, the travel time and fuel consumption were measured during the passage of a passenger car on the route from the planned initial node to the final node of the future bypass. The obtained results were referred to the study of traffic density within DK 22 carried out by GDDKiA Branch in Gdańsk and traffic intensity studies on the intake roads to the city carried out by the Transprojekt Gdańsk design company, which allowed to calculate the level of fuel savings, time and reduction of CO2 emissions to the atmosphere, thanks to transfer of transit traffic outside the city limits.

Abstract The study covered an urban river valley, strongly transformed due to the transport infrastructure development. The paper evaluates changes in spatial management of the valley section passing through the city centre that occurred during the past two centuries (long and short term phenomena) as well as their effect on selected environmental components. The basic spatial analyses were carried out with the use of specialised software, cartographic materials and photographic and descriptive documentation of the studied area (archival data). The most unfavourable changes in the potential of the valley environment occurred over the past few decades. They are manifested in a considerable deterioration of landscape values as well as the quantity and quality of water resources. Relationship was identified between water quality and intensity of motor vehicle traffic near the river. Despite the progressing urbanisation of the valley, revitalisation procedures can be still carried out and attractive space in the city centre can be created. In order to demonstrate the reasonableness of the presented concept, the paper suggests that urban succession should be incorporated as a term covering time trends and accumulated transformations. It can be helpful in analysing and determining the directions of development in disputable situations.
