Summary. The programing documents of the European Union determine the direction of transport systems development, including large cities and agglomerations. The context of these actions which aim to transform into ecologically clean and sustainable transport system is a significant reduction of greenhouse gas emissions. Assuming that public transport will significantly reduce the use of combustion-powered buses, studies on urban logistic enabling the use of electric buses for public transport are needed. The article presents the variants and scenarios for electric buses implementation in urban public transport, as well as the decision algorithm to support electric bus implementation based on technological, organisational, economic and ecological variables.
TRANSPORT PUBLICZNY W AGLOMERACJACH Z WYKORZYSTANIEM AUTOBUSU ELEKTRYCZNEGO -TENDENCJE ROZWOJUStreszczenie. Dokumenty programowe Unii Europejskiej wytyczają kierunki rozwoju systemu transportowego także w dużych miastach i aglomeracjach. Kontekstem tych działań, mających na celu przemianę systemu transportowego w transport ekologiczny i zrównoważony, jest znaczące ograniczanie emisji gazów cieplarnianych. Zakładając, że w transporcie publicznym nastąpi znaczne ograniczenie wykorzystania autobusów z napędem spalinowym, niezbędne są badania nad logistyką miejską, umożliwiające wykorzystanie autobusów elektrycznych do transportu publicznego. W artykule przedstawiono warianty i scenariusze wdrażania autobusów elektrycznych w publicznym transporcie zbiorowym oraz zaprezentowano algorytm wsparcia decyzji na podstawie zmiennych technicznych, organizacyjnych, ekonomicznych i ekologicznych.
The article presents threats related to broadly understood cybersecurity, encountered in modern public transport, especially in cases of increasingly introduced Intelligent Transport Systems (ITS). Experience to date has shown strong links between the technical sphere and IT system of public transport, ensuring its protection against unwanted externa l interference from people (or organizations) trying to disrupt its functioning. The following - inter alia - are of a key importance: the system of existing bus network as well as organization of bus work on routes (schedule) and its IT links, monitoring and system protection against external interference. The main goal of cybersecurity in public transport is to increase the level of cybersecurity in city agglomeration by increasing the availability of hardware and IT tools, included in intelligent transport systems, protecting safety and reliability of operation of public transport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
