The Price of Speeding – Planned and Actual Travel Speed

Balázs Horváth — 2025-10-31

Nowadays, traffic on motorways is extremely sensitive to disturbances. The situation is further aggravated by inhomogeneous speed selection. We examined the Győr-Budapest section of the M1 motorway using a microscopic traffic simulation method. During the study, we sought to determine the extent of delays experienced by travellers at different target speeds compared to the planned travel speed as the average speed. The long-term goal of the research is to demonstrate the impact of changing speed limits on traffic flow
homogeneity, overall time loss in traffic flow, and the social cost of traffic.

The Impact of Centrality in Public Transport Networks

András Munkácsy — 2025-10-31

Transport networks play a key role in the development of urban areas, influencing their importance and structure. In this study, we assessed centrality in Budapest by examining the public transport network. We analysed network centrality indicators using closeness, betweenness, straightness, and degree centrality. By combining the indicators, we identified areas with high centrality and potential future centers. For a broader structural perspective, we also calculated the average centrality levels for each district. From a methodological perspective, this research provides a new approach applicable to any city. In the context of Budapest, it offers practical results for urban planning and mobility development.

The Impact of Conditional Stops on Timetable Stability

Ámon Takács — 2025-10-31

The effect of conditional stops on railway timetable structure is worth examining from several aspects. The flexible element integrated into the fixed system raises additional possibilities while improving schedule regularity. The article demonstrates, based on the evaluation of annual delay data and OpenTrack simulation analysis, that even the current system without departure signal equipment improves timetable regularity and results in social benefits.

Background and Lessons from the History of Railway Property Development. Part 2

László Köller — 2025-10-26

This series of articles is about property management in railway areas from the change of regime to the present day. In a market economy, real estate has regained its traditional importance in the economy, its importance in the use of railway areas has also increased. Building on this, the article explores the evolving role and objectives of railway property management, from the beginning to the development of complex railway and property development plans. Through concrete examples, it describes issues relating to the use of railway land and the lessons that can be learned from them. Railway stations, passenger stations, and freight transport areas, marshalling yards, which have slightly different characteristics, are discussed in a separate group, along with their utilization plans and results and failures of them. At the end of the article series, the general conclusions and suggestions drawn from the practice so far are summarised based on concrete examples. At the end of the series of articles, general conclusions and recommendations based on specific examples will be summarized, which are particularly relevant considering the recently publicized brownfield development program in the Rákosrendező area. Part 2 covers the presentation of Déli, Keleti and Józsefváros railway stations.

The Development of the Road Traffic Safety Situation in the European Union and Hungary

Viktoria Ötvös — 2025-10-31

In recent years, road safety trends in the European Union and Hungary have shown variation. The number of accidents and injuries increased until 2018, after which it levelled off in 2019. Restrictive measures during the
pandemic led to a significant reduction in road traffic, which also affected the number of accidents. From 2021 to 2024, we could not measure a permanent, long-term improvement in terms of accident and injury numbers, thus the goals set for the decade (halving the number of road traffic fatalities and serious injuries) began to drift away from the actual experienced values. This article analyses the development the number of road traffic accidents, the ratio of fatal and injury accidents, as well as accident statistics by various age groups and genders.

The environmental impacts of the growth of passenger vehicles exceeding the rate of population growth in the Győr agglomeration

Orsolya Farkas — 2025-10-31

We analyzed the change in the population of the Szigetköz settlements (Győrújfalu, Győrzámoly, Győrladamér, Dunaszeg) located in a part of the Győr agglomeration, along road number 1401, between 2001 and 2022, the growth of the passenger vehicle fleet and the development of commuting habits. We performed the emission of harmful substances from road transport (including only passenger car traffic) with the COPERT program, thus quantifying a small part of the environmental impact of suburbanization.
