Technical Possibility

Modern large cities include both historically developed central parts and rapidly developing peripheral neighborhoods. Today, transport flows are formed not only by traditional bus, trolleybus, and tram routes, but also by significant fleets of taxis and private vehicles. An increase in traffic load and a shortage of parking spaces significantly reduces the capacity of roads and negatively affects the environmental situation. Ensuring transport accessibility based on the development of underground urban transport, the metro, is accompanied by great labor intensity, time and financial costs. Residents of large cities try to use bicycles, electric scooters, monowheels for intra-city movements. However, in winter in Russia this type of ecological personal transport becomes less accessible. A promising option for the development of public transport for large cities with a significant length of the street network in the absence of the technical possibility of expanding the roadway, can be an elevated electric transport (monorail). Using the example of the city of Samara, where the level of automobilization in 2019 reached 344 cars per 1000 people, the possibilities of developing the transport system of a large city with the inclusion of a monorail transport section in such a system are considered. This innovative solution will improve transport accessibility and reduce the negative impact on the urban environment. The average payback period of the project will be 4.4 years.

Current Value

The paper deals with the topical problem of the large cities development – to improve the quality of ser-vice for the population by electric municipal transport and to solve this problem by informatization of the management system. Currently, various information systems are widely used to support the work of dispatch services. The paper provides an overview of such systems. It is shown that dispatchers are pro-vided with real-time data on the technical condition and position of transport units on the route. Thus, the main means of ensuring the high-quality work of urban transport by dispatch services is the drawing up of traffic schedules based on some statistical data and heuristics, monitoring the implementation of this schedule and making decisions based on these data. At the same time, data on the current value of passenger traffic are not known and are not taken into account. Passenger traffic is a value of a complex nature, the current value of which may differ significantly from the provided traffic schedule. The paper provides data of model studies on real data (for Kharkiv city). It is shown that in large cities the proba-bility of denied boarding can be critically high even with small deviations in occupying and intervals from the provided values by the traffic schedule. The concept of an information system is proposed, which in real time visualizes on the dispatcher’s screen not only the position, but also the degree of loading of transport units on the route. It is proposed to determine the occupancy rate of the vehicle by the power consumed by the electric motors while driving. The fundamental possibility of such approach is shown on the example of simple model. It is indicated how this model can be improved as well. It is essential for the practical implementation of the system that modern trams are equipped with all the necessary devices: a speedometer, an inclinometer, a wattmeter and GPS sensors. The basic principles of building the architecture of such an information system are given. The current data of the devices is read and sent to the server for processing. The processed data is divided into two streams. One stream is intended for online visualization of the situation on the routes on the dispatcher’s monitor. Another stream is data that is transferred to the repository for storage and further processing.

The Impact

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.

Overall Performance

Robustness studies on integrated urban public transport networks have attracted growing attention in recent years due to the significant influence on the overall performance of urban transport system. In this paper, topological properties and robustness of a bus–subway coupled network in Beijing, composed of both bus and subway networks as well as their interactions, are analyzed. Three new models depicting cascading failure processes on the coupled network are proposed based on an existing binary influence modeling approach. Simulation results show that the proposed models are more accurate than the existing method in reflecting actual passenger flow redistribution in the cascading failure process. Moreover, the traffic load influence between nodes also plays a vital role in the robustness of the network. The proposed models and derived results can be utilized to improve the robustness of integrated urban public transport systems in traffic planning.

Alternative Energy Sources

In urban areas, the transport sector is one of the main sources of significant energy consumption and carbon emissions. Although diesel and gasoline are still the main sources of energy used in urban transport, more and more attention is now being paid to alternative and transitional sources of energy, as they are renewable and have less negative impact on the environment. However, the successful use of alternative energy sources can be hindered by various technical, economic and political factors. This article discusses the latest literature on alternative and transitional energy sources in order to understand the possibility of their use in urban transport at present, as well as the possibility of introducing these sources in the future

The article provides information about the state of Magnitogorsk electric transport during its formation. This is one of the steps to preserving the history of emergence and development of tram traffic, an attempt to outline its fundamental role in formation of the transport system, as well as in socio-economic and political life of Magnitogorsk, one of the first so called social cities of the Soviet Union. The article is structured into sections relating to expansion of the tram route network, state and development of tram fleet. The considered time period captures the years of the Great Patriotic War and is limited to the beginning of the «thaw» in the domestic political life of the Soviet state. Through systematization of documentary evidence, the fundamental role of tram traffic in formation of the transport system of Magnitogorsk for the studied time period is determined. This should contribute to development of information support for research on the historical patterns of formation of urban transport systems in the period of industrialization.This issue offers the first part of the article.

The bicycle has gone from being an old-fashioned recreational product to a less polluting means of transport and a compact, ultra-light personal mobility tool. This is how electrical bicycles will be used as the pillar that could support individual public transport in large cities worldwide. The objective of this manuscript is to detect how worldwide research on the electric bicycle is being developed, and, especially, around which scientific domains is it clustered, to finally identify the main trends in the field. This study has been carried out based on the Scopus database, where all the publications related to the topic of the electric bicycle have been analyzed up to the year 2017. ¨Therefore, research on the global research trends of this topic was conducted. Its evolution over time shows that since 2008 the growth of publications is much higher than in the previous period. The main countries are China and the USA, and it can be inferred that there are two major trend countries with high environmental awareness, which also have a large population and that the electric bicycle is a suitable and sustainable form of transport. Among the main scientific fields, engineering leads in research. The keyword analysis shows that the central theme is electric, then battery and motor stand out. A community detection was applied to detect the six main clusters of this research, largely dedicated to the following topics: Transportation–Environment, Electrical Engineering, Safety, Batteries, Sporting Goods–Urban Planning, and Mechanical Engineering. This manuscript shows that global research trends about the electric bicycle are increasing, and that it should be considered a means of sustainable urban transport and will therefore contribute to energy saving and sustainable energy.

Having been used extensively since the 1980s, the concept of social exclusion has given a new impetus to the discussions of poverty and disadvantageousness. The concept of social exclusion, which can be defined as the condition in which certain individuals or social groups cannot integrate into the society either socially or economically or politically, leads to social cohesion problems. This triggers segregation of the society, particularly in large cities, in both social and spatial terms. In the context of accessibility, “urban transport” appears as one of the most important factors determining level of social inclusion/exclusion of the individuals or groups. In this study relation between social exclusion and transport has been evaluated as an attempt to identify socio-spatial segregation pattern of Ankara.
