Opis:: Trolleybus transport was a very popular mode of transport in the past. Trolleybus systems have existed in more than 70 countries of the world. The maximum number of trolleybus systems (366) was operated in 1949. Today, this number is only 286, and mostly it is popular in the post-socialistic countries. Nevertheless, trolleybus systems of different countries have significant differences in the terms of construction and are being exploited in different ways.

Opis:: Widespread usage of emission free public transport is the preferred strategy in many cities to reduce a congestion and pollution from the road traffic. The trolleybus is a kind of urban public transport, i.e. a fully electric vehicle, which is considered as a promising tool to enhance the efficiency of public transport and to attain the goals of sustainable development and quality of city life. The operation control of service brake system and secondary brake system (the braking torque of traction electric motor) is realized with help of one pedal in the trolleybus. Thus, there are modes of the joint operation for these systems during the braking process. Authors focus on the development of rule-based algorithm for the blending control of traction electric motor and anti-lock braking system to enhance the overall braking efficiency of a vehicle. The mathematical model of the trolleybus braking dynamics was developed for this purpose. Test bench and ride tests on different road surfaces were carried out to determine the parameters of vehicle braking efficiency and to validate the developed mathematical model. The corresponding experimental data were used to analyse the efficiency of proposed rule-based strategy for the blending control of traction electric motor and anti-lock braking system of the trolleybus. As a result, the availability of proposed control algorithm is confirmed, which secures the required braking efficiency and provides a high braking stability of the vehicle.

Opis:: The article analyses the performance characteristics and operating costs of the three types of trolley-buses equipped with alternative energy sources, which are used by the MPK (Municipal Transport Company) in Lublin. The selected applications are adapted for driving off traction in emergency mode as well as servicing the regular route. Two of them are based on electrochemical batteries and one uses a system with an electric generator driven by an internal combustion engine.

Tytuł:: Transformations of urban electric transport in Ukraine after 1991 in the view of transport policy

Opis:: The article presents, in a multifaceted manner, the changes that occurred in urban electric transport in Ukraine after 1991. The purpose of the article is to research the diversification of the degree and directions of development and transformation of urban electric transport systems in the context of the transport policy. The legal and financial conditions for the functioning and development of the system are discussed, and a SWOT analysis of the current situation is carried out. In order to assess the direction of the changes occurring on individual networks, a synthetic index was used, constructed on the basis of the statistical data from 25 years available. The research has shown that in 1991‒2016, in the vast majority of Ukrainian cities there was a regression in urban electric transport, the largest in the east of Ukraine. That was of a bipartite nature: in the first years it practically applied to all networks, later a polarization in cities occurred ‒ in parts of cities the situation of urban electric transport has improved slightly. In the context of numerous diagnosed problems, the challenges faced by urban electric transport in Ukraine were indicated.

Opis:: The issue of electric energy saving in public transport is currently becoming a key area of interest, a fact connected with both an increase in society’s environmental awareness and a rise in the prices of fuel and electricity. Electricity can be saved by reducing transmission losses in the supply system. The article presents a method of measurement and analysis of transmission losses in the supply system of electrified public transport on the example of trolleybus transport in Gdynia and Lublin in Poland.

Tytuł:: Trends in the development of trolleybus transport in Poland at the end of the second decade of the 21st century
Trendy rozwojowe transportu trolejbusowego w Polsce pod koniec drugiej dekady XXI wieku

Opis:: Trolleybus transport played a changing role in Poland. Historically, these were both periods of dynamic development and rapid regression. The article analyzes the period from 2004 to 2018. An attempt was made to systematize and organize information on the development of trolleybus transport in this period. The available scientific literature as well as the economic, organizational and technological conditions for the functioning of trolleybus transport were analyzed. The analyzed period was undoubtedly a time of dynamic development of all three existing trolleybus systems in Poland. The structural funds of the European Union played a significant role in this, allowing to revitalize neglected and underinvested systems. At the same time, climate change has influenced global and local conditions in terms of the approach to transport in cities. Trolleybuses perfectly respond to the demands to reduce emissions from transport in cities. Also thanks to the development of battery technologies, trolleybuses have become more flexible in operation. The article compares the years 2004 and 2018, additionally illustrating the changes taking place on the maps.

Opis:: The antilock brake system (ABS) was developed, which coordinates actions of auxiliary and working braking systems of a trolleybus. A trolleybus type 321 "Belkommunmash", equipped with the proposed ABS was tested in road conditions. The results of tests confirmed compliance of the trolleybus with requirements of the rules UN EEC No 13. Decrease in slippage of the driving wheels, improved stability, roadability and traffic safety of the trolleybus was noted.
Opracowano przeciwpoślizgowy system hamulców (ABS), który koordynuje działanie dwu systemów hamowania trolejbusu: roboczego i pomocniczego. Trolejbus typu "Belkommunmash 321", wyposażony w proponowany system ABS, był testowany w warunkach drogowych. Wyniki testów potwierdziły zgodność trolejbusu z wymaganiami normy UN EEC No 13. Odnotowano zmniejszenie poślizgu kół napędzanych, poprawę stabilności trolejbusu, lepsze trzymanie się drogi i lepsze bezpieczeństwo w ruchu.

Opis:: Urban transport in countries of East-Central Europe, including the Czech Republic, Poland and Slovakia, played an important role in the residents’ daily mobility. The underdevelopment of individual motorisation contributed to the lasting significant role of public transport. Due to the operating characteristics of electric vehicles, as well as emerging fuel crises, electric public transport played a key role, especially in large cities. Differences in the development of economies in the electrotechnical segment influenced the structure of public transport in the analysed countries. The higher level of development of the Czechoslovak transport sector contributed to a greater share of trams and trolleybuses in total transport. Despite many development plans in Poland, the process of developing traditional means of electric transport slowed down with the political change in 1989. The situation was slightly different in the Czech Republic and Slovakia, where, despite financial difficulties, the development of tramway and trolleybus networks continued. Modernisation of public transport began after joining the European Union. Technological development has led to the emergence of a new means of transport –electric buses. The apparent ease of putting them into service revolutionised the situation in Poland, thus popularising electric transport. The situation was different in the Czech Republic and Slovakia, where the main focus was on the development of tramway and trolleybus transport. The article reconstructs the development of urban electric transport after 1989 in the analysed countries and identifies factors that differentiate contemporary transport development policies in the Czech Republic, Poland and Slovakia.
