The main source of delays in public transport systems (buses, trams, metros, railways) takes place in their stations. For example, a public transport vehicle can travel at 60 km per hour between stations, but its commercial speed (average en-route speed, including any intermediate delay) does not reach more than half of that value. Therefore, the problem that public transport operators must solve is how to reduce the delay in stations. From the perspective of transport engineering, there are several ways to approach this issue, from the design of infrastructure and vehicles to passenger traffic management. The tools normally available to traffic engineers are analytical models, microscopic traffic simulation, and, ultimately, real-scale laboratory experiments. In any case, the data that are required are number of passengers that get on and off from the vehicles, as well as the number of passengers waiting on platforms. Traditionally, such data has been collected manually by field counts or through videos that are then processed by hand. On the other hand, public transport networks, specially metropolitan railways, have an extensive monitoring infrastructure based on standard video cameras. Traditionally, these are observed manually or with very basic signal processing support, so there is significant scope for improving data capture and for automating the analysis of site usage, safety, and surveillance. This article shows a way of collecting and analyzing the data needed to feed both traffic models and analyze laboratory experimentation, exploiting recent intelligent sensing approaches. The paper presents a new public video dataset gathered using real-scale laboratory recordings. Part of this dataset has been annotated by hand, marking up head locations to provide a ground-truth on which to train and evaluate deep learning detection and tracking algorithms. Tracking outputs are then used to count people getting on and off, achieving a mean accuracy of 92% with less than 0.15% standard deviation on 322 mostly unseen dataset video sequences.

State Of Art

The purpose of this article is to present a state of art implementation of air quality sensors in public transport stops. Effects on health due to different types of pollutants are summarized as well. Functional scope of the solutions, via warning messages displayed for passengers waiting at these stops, including a cross system communication between traffic management and public transport systems, are also focused. Analysis of existing sensor types from multiple view point including functions, types of measured pollutants, price ranges and comparisons are outlined.

Terminal Station

Public transport systems can be characterised by a schedule-based or a frequency-based framework according to the kind of service to be operated. In the former case, specific departure and arrival times are set for each run and disclosed to the users; in the latter, instead, it is necessary to maintain a certain headway between two successive runs, rather than a specific timetable structure. This paper focuses on modelling frequency-based systems, which can be described by means of the so-called Merry-Go-Round (MGR) paradigm. The paradigm is first discussed and the related analytical formulation is presented; the role of the terminal station layout is then investigated within this framework. Finally, in order to show the effectiveness of the proposed formulation, it was implemented in the case of a real-scale metro line.

The Impact

The dynamic development of urban areas has created the need to adapt computer systems used to increased passenger traffic. Increasingly common phenomenon of congestion, contributed to intensify efforts to improve the efficiency of the control flows in agglomerations. For this purpose cities begin to use more and more modern-solving software to improve the functioning of public transport. The aim of the article is to assess and review of current solutions that can be successfully implemented in communication systems, cities in Poland. The publication is also intended to determine the prospects for the development of intelligent transport systems in the future as well as the effects resulting from their continued use.

Intended Effect

Traffic management in a city, even assisted by intelligent transport systems, is a very complex process. Analyzing a single intersection may not produce the intended effect or even contribute to a deterioration from the initial state. The most important element of introducing changes should be traffic monitoring. The article presents the influence of traffic lights on the functioning of public transport, on the example of Kosciuszko Square in Wroclaw. Presented proposals were preceded by several hours of traffic observations, some of the results were presented at this paper. The article proposes changes to streamline public transport within the square.

The authors of the article seek to determine the nature, characteristics and main directions of development of transport infrastructure in the municipality of Tyumen; to describe the management system for development of transport infrastructure; to develop a model for improving the management of transport infrastructure in the city of Tyumen, to identify measures for improving regional and municipal legislation; to make recommendations for the system of municipal authorities. The study is based on the basic principles and methods of development of transport systems of municipalities. The authors conclude that only implementation of a complex integrated policy at the state level based on the synthesis of transport management systems, urban planning, land use and traffic management is able to resolve current problems in the transport infrastructure of Russian cities. Federal monitoring and control of compliance of public transport services with the quality standards along with responsibility of heads of municipalities will become the main incentives for the priority development of public transport in Russian cities.

Abstract Relationships between the activities of bus carriers and rail passenger traffic (and the railway offer) are examined in this article. The study was carried out in peripheral areas located at the Polish and Czech borderlands in Lower Silesia province. High quality rail transport generally increases the demand for transport services. Therefore, the proper development of transport offer plays a key role in the functioning of public transport systems, the backbone of which is rail transport. The study also shows that under conditions of transport market deregulation, bus carriers have developed a competitive network which is not complementary to rail transport. As a consequence, the deregulation of the transport market has increased the risk of transport exclusion.
