Significance and potential of transport decarbonization in cities

Abstract: Urban public transport serves up to approximately 40 % of mobility needs. Since around 30% of urban greenhouse gas emissions come from transport, the decarbonization of public transport is crucial for the sustainable development of cities. The mass nature of public transport and its ongoing decarbonization, driven by electromobility, increase the strategic importance of this system in urban climate protection efforts. Scientific research highlights the growing significance of this issue and its practical implications. In particular, a multidimensional perspective on decarbonization pathways and their impact on the competitiveness of public transport, as well as individual cities, is essential. A review of the literature and conducted research indicate that this is a highly relevant topic with significant theoretical and practical potential.

Key words: public transport, decarbonization, electromobility

Optimising the routing of public transport lines using PTV Visum

Abstract: This article presents a methodology for designing and evaluating the efficiency of public transportation routes using traffic simulation modelling in PTV Visum software, highlighting the new functionality called the Public Transport Line Constructor (PTLC). The authors emphasize the necessity of simulation-based testing of new transportation offerings due to the risks and costs associated with direct experimentation on operational systems. Particular attention was given to comprehensive performance evaluations of the new network’s complexity and effectiveness. The study analysed two optimisation scenarios for a new bus network in the city of Halle using PTLC, resulting in increased passenger numbers and improved service quality indicators. The authors also noted the limitations of the applied method, such as the inability to create circular lines and constraints in defining maximum vehicle-kilometres. Despite these limitations, the tool was considered valuable and recommended for further research and practical applications.

Mobile digital road card in the organization and calculation of public transport services

Abstract: This article addresses the issue of the possibility of replacing the paper roadcard document in public transport with a digital version of this document. The roadcard, as a required transport document, exists in both freight and passenger transport. In freight transport, the roadcard, also known as a waybill, is an important supply chain management document that has seen numerous digital implementations. The mobile road card has been in operation for several years as an electronic document with almost all rail operators in Poland. Since almost 30 years ago, when the first computer programmes supporting transport planning, dispatching and billing were implemented, it has not been possible to dispense with paper toll cards in public transport until today, except for a few urban public transport operators that have implemented the mobile electronic toll card in the last two years. This article presents the concept of the digital toll card as a mobile application for public transport drivers, which at the same time provides a medium for an extensive online information exchange between the company, its transport dispatch centre and the driver.

Key words: transport, digital road card, transport dispatching

Modern technologies and IT support in public transport on the example of Suwałki

Abstract: The article presents the functioning information systems and modern technologies applied to public transport in Suwałki. These include: Traffic Management System for public transport vehicles, Dynamic Passenger Information System and Ticketing System. The implementation of these IT systems has played a key role in the development and optimization of urban public transport in Suwałki. Thanks to European Union funding, it was possible to introduce many new IT systems, such as electronic timetables, voice announcements in vehicles, vehicle monitoring systems or online ticketing platforms, which enable better organization and management of public transport. An analysis of available solutions has shown that their use helps to increase transport efficiency, improve passenger comfort and enhance safety. At the same time, the development of these technologies requires further investment, staff training and constant monitoring and adaptation of the solutions to the needs of residents. Therefore, the city authorities are constantly striving to introduce more innovative solutions in urban public transport.
