Transport Management

Efficient management of smart transport systems requires the integration of various sensing technologies, as well as fast processing of a high volume of heterogeneous data, in order to perform smart analytics of urban networks in real time. However, dynamic response that relies on intelligent demand-side transport management is particularly challenging due to the increasing flow of transmitted sensor data. In this work, a novel smart service-driven, adaptable middleware architecture is proposed to acquire, store, manipulate, and integrate information from heterogeneous data sources in order to deliver smart analytics aimed at supporting strategic decision-making. The architecture offers adaptive and scalable data integration services for acquiring and processing dynamic data, delivering fast response time, and offering data mining and machine learning models for real-time prediction, combined with advanced visualisation techniques. The proposed solution has been implemented and validated, demonstrating its ability to provide real-time performance on the existing, operational, and large-scale bus network of a European capital city.

Future Vision

The smart city transport concept is viewed as a future vision aiming to undertake investigations on the urban planning process and to construct policy-pathways for achieving future targets. Therefore, this paper sets out three visions for the year 2035 which bring about a radical change in the level of green transport systems (often called walking, cycling, and public transport) in Turkish urban areas. A participatory visioning technique was structured according to a three-stage technique: (i) Extensive online comprehensive survey, in which potential transport measures were researched for their relevance in promoting smart transport systems in future Turkish urban areas; (ii) semi-structured interviews, where transport strategy suggestions were developed in the context of the possible imaginary urban areas and their associated contextual description of the imaginary urban areas for each vision; (iii) participatory workshops, where an innovative method was developed to explore various creative future choices and alternatives. Overall, this paper indicates that the content of the future smart transport visions was reasonable, but such visions need a considerable degree of consensus and radical approaches for tackling them. The findings offer invaluable insights to researchers inquiring about the smart transport field, and policy-makers considering applying those into practice in their local urban areas.

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

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.

Time Period

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.

Large public events are quite common and lead to peak usage of urban transport systems. Clear planning and communication processes which involve relevant parties for event management, traffic and security issues are needed due to the increasing number and complexity of events. When planning an event, overall organizational and technical issues as well as the preparation for unexpected incidents are asked for to plan for maximum safety and security. Within the research project VeRSiert1, a web-based information and cooperation portal was designed for the region of Cologne and implemented for these purposes. Its intention is to support collaboration of the participating organizations prior to, during execution and post-event analysis of a large public event, while taking into account unplanned risks ranging from storms to acts of terrorism.
