Energy Consumption in Tram Transport
Get PDFRail transport through the use of electric traction is more friendly for environment than other means of transport. It has a lot of benefits, mainly: the possibility of mass transport using as little energy as possible per one passenger, reducing crowd, reducing congestion, lower emission of pollution, weatherproof, more safety, regularity of travelling.
As we can see from the above mentioned benefits, public tram transport is one of the most popular means in Poland. Tram market in Poland is one of the largest in the world. Nowadays we have 14 thousand tram lines used by 16 companies, which gives a total of above 3600 cars. We have many types of trams exploited at present. The most popular are cars 105Na, characterized by low comfort for passengers, too low durability and high energy
consumption. Because these cars are at present exploited, on the basis of their structure many different modernizations are made. The examples could be two types of cars : 204WrAs and 205WrAs , which have been produced since 2005 by the Wrocław PROTRAM Company.
The largest Polish cities also use a modern trams stock produced by the largest Polish construction companies. One of the examples is recently using five-cars type 120Na produced by PESA company. This article presents results of measurements of energy consumptions of trams 105Na using traditional start –up resistance and trams PROTRAM 205WrAs type with asynchronous propulsion system in IGTB technology. Then the energy consumption is compared with data obtained from manufacturer of a modern tram PESA 120Na, working in the same conditions – asynchronous propulsion system
Models of the Impact of Road Transport in Air Quality Management System
Get PDFThe paper presents categorization of models used in environmental monitoring taking into account the factors of emissions into the air, and the impact of road transport emissions. The information collected was related to the share of road transport in the creation of the emission in the Lodz region, analyzed as a case study. Types of substances were classified according to their harmfulness and intensity derived from traffic sources. Particular attention has been given to the issue of dispersion models used in environmental monitoring, the practice of their use and suitability for road transport
The Role of Packaging Supply Chain in Food Packaging Safety Assurance
Get PDFThe article is devoted to the issue of maintaining food packaging safety across its supply chain. It is essential to assure the safety of packaging, which is possible only by implementation and maintenance of specific safety assurance systems and standards used in the food industry. Food packaging enterprises are obliged to carry out activities and provide appropriate conditions to assure the safety of packaging materials and packaging intended to come into contact with foodstuffs. The article presents the results of research, conducted among packaging supply chain enterprises, on the level of compliance with the requirements
The Importance of Logistic Risk for Achieving Corporate Social Responsibility Goals in Supply Chains
Get PDFVarious supply chain stakeholders show an increasing interest in environmental and social issues related to business, since it has become a crucial factor in creating competitive advantage. Among the concepts that have been used – apart from CSR – are sustainable development, corporate citizenship, sustainable entrepreneurship, the triple bottom line, and business ethics. The need for CSR in supply chains should particularly be seen in light of the fact that a large part of their operations is conducted through systems of governance, which link firms together in various sourcing and contracting arrangements. Corporate social responsibility (CSR) is a concept of large relevance for business in general and within logistics specifically. Responsibility of businesses involved in supply chains can increasingly be found high on the CSR-agenda of European companies and governments. However, despite all these efforts and standards, a number of CSR issues connected to logistics issues still remain unsolved. One of these areas is the relationship between risk situations and social and environmental issues, which companies in the supply chain try to manage. In literature many different sources of logistic risks for supply chain management were discussed. Even though there is a stream of literature investigating risk in supply chains, there has been little research applied to the precise analysis of logistics risk within the framework of the CSR concept. The purpose of the research presented in this paper is to provide insight into the role of different types of risk connected to logistics processes while implementing the main areas of the CSR concept
The Identification of Selected Imperfections of Electric Traction Motors
Get PDFElectric traction motors of rail vehicles operate in very harsh conditions. This is due to their varying load and power fluctuations, as well as their exposure to high humidity, excessive shocks, dust and changing ambient temperature.These conditions can lead to the non-operational state of motors in operation which should be identified as soon as possible. This requires building the mathematical model of a traction drive system, which enables the full simulation of its work in real time. It also requires interference in the construction of the electrical system that allows for measuring the values of the relevant diagnostic features. The measurements of these features and their comparison to the values obtained from the mathematical model with the use of a multi-valued evaluation constitute the basis for the formulation of the operational diagnoses of traction motors
Criminal Law and Institutional - Managerial Aspects of Ensuring Safety in Rail Traffic. Selected Problems
Get PDFThis article offers insights into criminal law aspects of rail accidents on the ground of 4 E theory. The authors show correlations between offences against safety in transport and criminal repercussions of this incidents. The concept of a rail disaster is scrutinized and the role of prevention in the process of ensuring safety is highlighted. In the further part of the article the readers’ attention is turned to the role and methods of managing a public institution which acts as the National Security Agency (NSA) in rail transport. The article discusses some ideas for the NSA management modernising process as well as the viability of developing the concept of New Public Management and logistics in offices of public administration
Transport Co-Modality and Intermodal Transshipment Terminals
Get PDFCo-modality means the efficient use of transport modes operating on their own or in multimodal integration in the European transport system to reach an optimal and sustainable exploitation of resources. Due to the growing demand for freight transport high efficiency and co-modality of different branches of transport in the European transport system are imperative. The basic criterion for assessing the effectiveness of all the available and proposed solutions must be economical bill, complex conducted both in terms of micro (at the level of each customer) and macro (at the level of the whole transport sector), endearing issues of economic, ecology, social, etc. An important aspect are the additional costs such as those related to the creation of new element of infrastructure, especially point elements of infrastructure
The Areas of Competition and Planes of Cooperation in The Polish Passenger Services Market (Sea, Rail and Air Transport)
Get PDFThe modern, global passenger services market operates in the circumstances of constantly evolving occurrences of competition and cooperation. In the interbranch transport relationships it is characterized by a variety of economic relations connecting market entities. The pace and direction of these transformations drive processes of globalization as well as liberalization and deregulation of this sector of services. Liberalization drives interbranch competition, whereas cost and political pressure stimulates development of various forms of cooperation. The article aims at demonstrating areas of competition and planes of interbranch cooperation in the Polish passenger services market with an example of sea, air and rail transport
