This article analyses road traffic accidents caused by motorcycle riders' technical errors. It presents an accident table that links the nature of the accidents to the causes of the accident. The connection provides a comprehensive overview of the typical motorcycle accidents that can be extended to events that have occurred. With this in mind, a conclusion can be drawn in the sense that an accident could have been avoided by a proper reaction of the motorcycle rider, and it would also make suggestions for developing a methodology for motorcycling education. Currently, motorcycling on the domestic road network is a hobby rather than a means of everyday travel, but the 10% participation rate in accidents certainly justifies the need to investigate this mode of transport. Today's state-of-the-art and technically well-equipped high-performance motorcycles require efficient vehicle handling and road use preparation. Therefore, drivers need to be able to respond appropriately to the challenges of our accelerated traffic.

“…This article presents a pilot-study for the above-described network research, focusing on the Hungarian capital, Budapest and its agglomeration area (Figure 1), which is a frequently researched area in transportation sciences, such as [16][17][18][19][20]. In general, Budapest is divided by the river Danube.…”

Disaster Risk Assessment Scheme—A Road System Survey for Budapest

This study presents a method to analyze the most critical elements of the public road system concerning outer effects which hinder the normal operation of the whole system. The surveyed public road network in Budapest, Hungary is studied as a graph: Dijkstra’s algorithm is applied to find the shortest path, and the Boykov-Kolmogorov method is used to calculate the maximum flow of the network. Those elements are identified whose damage can critically influence the operation of the network, and where the infrastructure available for rescue teams has a bottleneck. Finally, the Wilcoxon post hoc test was applied with Bonferroni correction. The tests have proven that the new method can successfully identify the critical vulnerabilities of the network to determine its weak points by considering reduced road capacities and the increased needs for transportation arising due to a disaster. This pilot study confirmed that after the elimination of the problems in statistical methods, the new framework can robustly identify those road network elements whose development is of key importance from a disaster management perspective.

“…The potential benefits of AVs (e.g. increasing safety levels, reducing road accidents and decreasing traffic congestion [4][5][6][7][8]) vary considerably by their penetration into the market [9]. Some researchers tend to create several scenarios to cover the possible cases of integrating AVs into road networks as this new technology is not yet entirely developed (see e.g.…”

Examining the Impact of Hysteresis on the Projected Adoption of Autonomous Vehicles

This study explores the potential impact of per capita gross domestic product (GDP) changes on the adoption of autonomous vehicles (AVs). The level of adoption of AVs is anticipated to influence the benefits of future mobility, prompting numerous studies that forecast the market share of AVs using various methods. The influence of changes in the per capita GDP on vehicle ownership is crucial in assessing the challenges associated with reducing dependence on AVs in the future. This phenomenon, known as the hysteresis effect, implies that AV adoption estimates may differ when the GDP is rising as opposed to when it is falling. This research examines the effect of rising and falling GDP per capita on the anticipated AV diffusion in Hungary, utilising a scenario-based method to account for the variation in adoption rates in the literature. The study findings indicate that declines in GDP in the past will impact AV ownership, leading to a shift in future adoption patterns. The AV market is projected to reach saturation in the 2070s and the 2090s in favourable and moderate scenarios, respectively, while a pessimistic state would delay this outcome until after the year 2100.
