Urban Public Transport

Dialectics, or developmental transformation, would eventually cause any system to change. The level and depth of these changes vary and depend on the power of external influence and system reservation mechanisms. The art of managing system processes consists of two main aspects. The first aspect involves the sagacity of managers and predicting general environmental change trends (and their impacts on the managed system). The second involves adjusting to these trends, maximizing possible benefits, and minimizing the negative manifestations of this process. Innovation plays an important role, contributing to system transformations with maximal effect and minimal loss. Public transport systems are important elements in cities, as they provide spatial mobility for at least half of the citizens of a city who cannot use individual transportation. Modern urbanization and peculiarities of the social–economic statuses of many citizens contribute to the fact that organized public transportation is unprofitable. The low solvency of citizens who use public transportation services means that passenger transport systems do not work with enough profitability. As a result, governing institutions often choose to subsidize unprofitable transporter activities, thereby prolonging the functioning of unprofitable routes. This is possible only in conditions of sustainability (in regards to a non-optimal system), when the environment is calm, and its negative impact is low. “Black swans” (according to N. Taleb) are bifurcation factors that break the sustainability of non-optimal system. Urban public transport (UPT) of a large Russian city, Tyumen, experienced it in 2020, in connection with the COVID-19 lockdown. The sharp decrease in population mobility in Tyumen, in 2020–2021, caused the need for a complete transformation of the transport service system. However, managers did not want to fundamentally change a system that consensually suited most counterparties. The search for new balances in a system that demands transformation is one way for sustainable provision. This article looks at the transformation and sustainability of a UPT system in the large Russian city of Tyumen, under conditions affected by the negative impact of COVID-19. Results of a comparative (i.e., pre-crisis (2019) and crisis (2020)) Pareto analysis of the contributions of different UPT routes are presented. Transformation of the structure of the UPT route system can overcome the “crisis” COVID-19 period and minimize its financial-economic costs.

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.

Urban Public Transport

Currently, the trends in urban public transport have been changing over the years in developing countries for mobilization and accessibility development. Urban public transportation systems are the most popular in Selangor State, including big cities such as the Klang Valley Region. Objective measures of spatial pattern and hotspots have been used to understand how urban public transport development relate to open access. This method relies on specific spatial information and available web-based tool that shows the pattern primarily based on given vicinity and statistics connectivity. To date, several studies have finished tested in developed countries. In this study, we use Geographic Information Systems to analyse and consider hotspots identification precisely and efficaciously. Therefore, in this paper, we focus on two types of point sample evaluations – Gi* hot spot and point density analysis evaluation as statistical operations. Public rail transport was evaluated as a validation to describe the percentage of distribution of open access. The final result, GIS mapping capabilities to show that GIS's technology offers to the variation of urban public transport relate to public services, is to create maps and spatial interpretations.

ResumenEl transporte público y el desplazamiento a pie en las ciudades son elementos clave para el desarrollo sostenible. Distintas ciudades han optado por la implementación de sistemas de transporte público masivo para mejorar la movilidad y promover un desarrollo sostenible. Diversos autores han hablado de la importancia de la marcha a pie como parte de los viajes en transporte público. Los radios de cobertura de las estaciones de metro en distintas ocasiones podrían considerar un aumento del desplazamiento a pie. La investigación se centra en aumentar la caminabilidad alrededor de las estaciones de metro en Quito, de manera que, el caminar puede cumplir una función de co-modalidad para el transporte público. A partir del análisis de la accesibilidad, la densidad y la diversidad de usos se propone una metodología que permite demostrar la validez de las variables seleccionadas para fomentar la caminabilidad en un punto de conexión con transporte público en un entorno urbano en su mayor parte consolidado.AbstractPublic transportation and pedestrian movement in cities are key elements for sustainable development.

Urban Public Transport

The functioning of passenger transport systems should provide necessary quality of passenger service. The results of this research have shown possibility to increase the quality of urban public transport via influence on the driver’s state due to the rational schedule planning. The state change patterns of drivers during the idle time on the final and intermediate bus stops were formalized, based on field observations. The following conclusion was made: decreasing of driver’s body stress takes place during the idle time on the route stops. The intensity of decreasing of driver’s body stress is inversely proportional to the meaning of activity index of driver’s regulatory systems before the start of standing time. Consequently, the duration of idle time must be differentiated depending on the value of the indicator of activity of driver’s regulatory systems before the start of standing time, which is influenced by the working conditions. ECG method was used for assessing driver’s fatigue in elements of transportation process. Comparative analysis of driver’s state changes during the different types of idle time shows the comparability of the results of the study. Transportation management experts can use the research results in urban transport schedule planning and monitoring.

Financial Mechanism

The purpose of the article is to assess the practice of attracting international sources of financial support for public transportation at the regional level, to identify problems with insufficient effectiveness of the implementation of international financial support projects and the formation of solutions at various system levels. It is determined that the main sources of financing of transport entities are self-financing, lending, state and international financial support. The preconditions for the use of credit funds of international financial donors for financing public transport and the conditions for lending to transport entities are described. Peculiarities of public transport lending by way of implementation of the project "Ukraine Urban Public Transport" are analyzed, and it is highlighted that its purpose is to realize the strategic priorities of the transport industry, institutional reforms and informatization. It is clarified that the responsibility for the performance gaps under the project, defined in the assistance agreements, is allocated to the City Councils and / or public transport entities. An assessment of international financial support is made and the reasons for short receipt of funds by transport companies from international financial organizations are specified. The amount of losses on incomplete implementation of the plan of expenditures and provision of credits for the realization of projects in the transport sector of Ukraine is clarified. Inefficiency in finding additional sources of financing of the project "Ukraine Urban Public Transport" is justified due to the impossibility to allocate financial responsibility to a certain project group in case of delay in non-implementation of the project plan at all levels. The organizational and financial mechanism of providing international financing for urban public transport by the European Investment Bank is proposed. It is argued that the mentioned mechanism, in contrast to the existing ones, identifies control points for the flow of financial resources, which provides an opportunity to suggest ways to intensify control activities by observers of the European Investment Bank and the public. The main disadvantage of receiving financing from the European Investment Bank in the framework of the project "Ukraine Urban Public Transport" is identified: obligations to pay VAT to the State budget are allocated to the business entity of the transport sector. The problems of inefficiency of implementation of financing sources of international financial organizations (on the example of the European Investment Bank) are identified and the directions of their solution are offered. The need for coordination of bodies of state supervision at the regional level with the observers' control activity is identified to promote the efficient and meaningful use of international financial sources by economic entities in the transport sector. It is proposed to supplement the state and supranational control with public control functions through the following options for establishing cooperation: 1) interaction of public councils at local self-government bodies with independent observers of international organizations involving auditors of the Accounting Chamber; 2) control of the process of implementation of the credit project of important infrastructure projects, including public transportation, by public organizations of the regional level. Methodology. In accordance with the purpose, the following research methods were used: a systemic approach (in identifying the components of the organizational and financial mechanism of international financial projects and their relationship), methods of comparative and statistical analysis (in assessing the receipt of financial resources from international financial sources). Results. The problems of inefficiency of implementation of financing sources of international financial organizations (on the example of the European Investment Bank) are identified and the directions of their solution are offered. Practical implications. Improving efficiency of using the international sources of financial support at the regional level will contribute to the renewal of the rolling stock of urban public transport, ensure its sustainable operation and development, save jobs at utility enterprises, increase revenues of utility enterprises from the provision of transportation services to the population. Value/originality. The organizational and financial mechanism for providing international financial support for urban public transport by the EIB has been developed, which, unlike the existing ones, identifies control points for grant flows, providing an opportunity to suggest ways to intensify control activities by the EIB observers and the public.

Travel Time Prediction

Road traffic congestion has become a global worry in recent years. In many countries congestion is a major factor, causing noticeable loss to both economy and time. The rapid increase in vehicle ownership accompanied by slow growth of infrastructure has resulted in space constraints in almost all major cities in India. To mitigate this issue, authorities have shifted to more sustainable management solutions like Intelligent Transport System (ITS). Advanced Public Transportation System (APTS) is an important area in ITS which could considerably offset the growing ownership of private vehicles as public transport holds a noticeable mode share in several major cities in India. Getting access to real-time information about public transport would certainly attract more users. In this regard, this work aims at developing a reliable structure for predicting arrival/travel time of various public transport systems under heterogeneous traffic conditions existing in India. The data used for the study is collected from three cities—Surat, Mysore, and Chennai. The data is analyzed across space and time to extract patterns which are further utilized in prediction models. The models examined in this paper are k-NN classifier, Kalman Filter and Auto-Regressive Integrated Moving Average (ARIMA) techniques. The performance of each model is evaluated and compared to understand which methods are suitable for different cities with varying characteristics.

Speed Up

There is a large number of tools for the simulation of traffic and routes in public transport systems. These use different simulation models (macroscopic, microscopic, and mesoscopic). Unfortunately, these simulation tools are limited when simulating a complete public transport system, which includes all its buses and routes (up to 270 for the London Underground). The processing times for these type of simulations increase in an unmanageable way since all the relevant variables that are required to simulate consistently and reliably the system behavior must be included. In this paper, we present a new simulation model for public transport routes’ simulation called Masivo. It runs the public transport stops’ operations in OpenCL work items concurrently, using a multi-core high performance platform. The performance results of Masivo show a speed-up factor of 10.2 compared with the simulator model running with one compute unit and a speed-up factor of 278 times faster than the validation simulator. The real-time factor achieved was 3050 times faster than the 10 h simulated duration, for a public transport system of 300 stops, 2400 buses, and 456,997 passengers.
