Road traffic crashes and their severity level are likely caused by variations in elevation, slope, and terrain formation. As far as our knowledge is concerned, the triangular irregular network (TIN) was not used to analyze dangerous zones of the road network with respect to traffic crashes' location. The main purpose of this study was to investigate a dangerous road network that was affected by traffic crashes using TIN. To address the goal, this study used elevation differences slope variation, and terrain between road traffic crash locations. The study used the intersection zone road network coordinates of traffic crashes in the city of Budapest that were recorded from 2017 to 2021. Using tools like ArcGIS and MS Excel, the study organized, modeled, and analyzed the data. Geometrical interval classification was used to classify the data in accordance with the characteristics of elevation deference and slope variation. Both inferential and descriptive statistics were engaged to explain, analyze, and summarize the findings. The results of this study demonstrated that the majority of traffic crashes occurred in locations with lower elevations and their differences, steeper/cliff slopes between points, and flat terrain. The finding was in contrast to what was observed in other studies. This study advocates that TIN is the optimal method and substitute for analyzing the risky zone of the road network at macroscopic level. © 2024 The Author(s).

AB - The safety of vulnerable road users is one of the most important aspects of road safety. One of the most critical points for pedestrian traffic is the pedestrian crossing, where pedestrians and vehicles interact. Due to the speed and weight of vehicles, sufficient attention by drivers and pedestrians is essential for accident-free crossing. Our research aimed to identify the parameters that influence drivers’ willingness to yield the right of way. The focus of our research was on the distractors of pedestrians and drivers. Our study involved on-site investigations. The measurements were taken at designated pedestrian crossings, with a road sign and road markings. During the measurements, we recorded all situations where there was a pedestrian-vehicle interaction. We recorded several parameters about drivers and pedestrians. The data were analyzed using both descriptive statistics and a discrete decision model. We have shown that the drivers’ willingness to stop depends on distractions. We showed that distractors on the part of pedestrians slightly increase the drivers’ willingness to stop, while distractors on the part of drivers strongly decrease the willingness to yield. In addition, we have shown that distractions from both sides result in the lowest willingness to yield the right of way. We have also shown that driver behavior depends on the gender, age, and behavior of pedestrians. Our results are valuable and useful in many ways in the field of road safety and the analysis of traffic behavior.

Kutatásommal célom a közlekedés biztonságosabbá tételéhez szükséges kulcsterületek feltárása és a lehetséges potenciális beavatkozási területek meghatározása volt. Munkám során a 2016–2020 közötti közlekedési balesetek adatait elemeztem leíró statisztikai módszerrel. Megállapítottam, hogy a leginkább kritikus pont a gyalogosok közlekedése. Azokban a balesetekben, ahol volt gyalogos sérült, a balesetek két okcsoportja dominál: gyalogosok hibája (34,3%), valamint a járművezetők gyalogosok részére történő elsőbbségadásának elmaradása (38,1%). Az eredmények lehetőséget adnak a további célirányos vizsgálatokra, valamint a hatékony beavatkozásokra.

AB - The level of greenhouse gas emissions is one of the most important issues today, both professionally and politically, because a lower level of greenhouse gas emission is mandatory for a sustainable economy. Besides industry and households, the transport sector is also responsible for these emissions. For this reason, it may be essential to set up a model with which the amount of CO2 emissions could be estimated or predicted. This article presents a model that examines the extent of economic development and CO2 emissions in European countries. The result is establishing a pattern requiring a longer time series. If the pattern is proven, a clear reassessment of the current relationship between economic development and environmental protection should be made.

The research was supported by Hungarian consortium of Electronic Information Service National Programme (EISZ) . AB - The road surface and its geometric condition affect the vehicle's desired operating speed. This paper is framed to examine an empirical model for the desired operating speed due to the variation of the side friction factor at horizontal road curvature across the design period. The minimum radius equation developed by the American Association of State Highway and Transportation Officials (AASHTO) was used to analyze the desired operating speed at the confessed minimum radius, maximum side friction factor, and superelevation. This empirical formula indicated that speed and side friction factors had a direct relationship. Even though this empirical equation cannot define the relationship between desired speed and side friction across the design period except at the opening phase of the road, based on the research gap indicated above, this study proposes an empirical model used to explore the desired operating speed that resulted from the variation of the side friction factor across the design period. To have a structured flow of ideas, a theoretical model was used to create the approach of the specific research inquiry. For exploration purposes, this study used a maximum superelevation of 8 %, the same minimum radius, and the AASTHO recommended side friction factor. Based on the proposed empirical model, this study confirmed that the desired speed increases and decreases as side friction decreases and increases, respectively. Except that vehicular movement is in a static state, at an unrealistic side friction factor (f = 0), and at a critical zone. © 2024 The Authors LA - English DB - MTMT ER - TY - JOUR AU - ABDULLAH, PIRES AU - Sipos, Tibor TI - Exploring factors influencing consumer preferences for automated driving vehicles JF - TRANSPORTATION ENGINEERING J2 - TRANSPORT ENGIN VL - 16 PY - 2024 PG - 10 SN - 2666-691X DO - 10.1016/j.treng.2024.100233 UR - https://m2.mtmt.hu/api/publication/34714781 ID - 34714781 N1 - Export Date: 18 March 2024 Correspondence Address: Abdullah, P.; Department of Transport Technology and Economics, Műegyetem rkp. 3, Hungary; email: pires.abdullah@edu.bme.hu AB - Adopting automated driving vehicles (AVs) promises to transform transportation systems, yet understanding individual preferences is essential for effective implementation. This study uses decision tree analysis to investigate the factors influencing preferences for partially automated vehicles (AV3) and fully automated vehicles (AV5). Surveys were conducted in the Duhok-Kurdistan Region of Iraq to explore attitudes toward AV technology. Respondents selected their preferred option from AV3 and AV5, with various factors considered in the analysis, including age, gender, frequency of trips, and mobility concerns. Results revealed a preference for AV3, with trip frequency emerging as a key determinant. Older respondents tended towards AV3. The number of trips was the most significant determinant in their decision-making process, with individuals who frequently traveled showing a preference for fully automated AVs. Furthermore, understanding these preferences can inform strategies for promoting AV adoption and integration into transportation systems, shaping future mobility. The study's contributions lie in its localized focus and the identification of key factors influencing AV preferences in a specific region. This insight can assist in developing tailored strategies to promote AV adoption and address mobility challenges.

AB - This article aims to investigate the socio-economic nature of car brand loyalty. The hypothesis is that brand loyalty is a complex structure with a complicated socioeconomic background. Nowadays, massive research is focused mainly on the psychographic background of the brand loyalty phenomenon. However, a socio-economic aspect of consumers is also entering into brand loyalty creation. It is supposed that brands with loyal consumers have more educative strength than brands where brand loyalty is missing. As it is challenging to identify consumers with a psychographic profile suitable for loyal brands, the changes in consumer behaviour are hard to reach. However, if the socioeconomic profile of loyal consumers is detected, environmental education can be focused precisely and with higher effectiveness. Some preliminary data have been collected in Slovakia to investigate the socio-economic background of car brand loyalty. To collect these data, a questionnaire survey has been used. It was realised in the last quarter of the year 2021 on the sample of 2035 Slovak inhabitants older than 15 years. Statistical analysis has been provided via a decision tree approach. It has been found that two relevant factors significantly influence brand loyalty - respondents' age and income. Based on these findings, it can be stated that, in general, brands with the higher proenvironmental communication potential in the case of the Slovak Republic are Škoda, Audi and BMW. An approach that includes the strength of pro-environmental orientation of consumers (focusing on age categories) confirms this order. However, in the case of the income perspective, Peugeot's list of car brands should be extended, which has been surprisingly identified as a car brand with the potential to be used widely in the scope of pro-environmental education in specific area’s conditions in the Slovak Republic.

AB - This research aimed to examine the spatial distribution of road traffic accidents in Budapest, Hungary. The primary objective was to identify the factors associated with traffic accidents on the city's transportation network and to determine the locations of the most frequent accidents during peak and off-peak hours. A quantitative methodology was employed in this study, utilizing a dataset of recent accidents that occurred between 2019 and 2021, classified into peak and off-peak incidents. The data was analyzed using Python software and Quantum Geographic Information System (QGIS) tools for big data analytics. These programs enabled the creation of spatial maps of the study area and the identification of accident spots based on latitude and longitude information. A decision tree classification approach was used in the machine-learning method implemented with Python software. Additionally, the dataset file was uploaded to QGIS, which applied the heatmap (Kernel Density Estimation) algorithm to identify accident hotspots. The study findings revealed that the city center was the most common location for accidents overall, with peak and off-peak times, lanes, and days of the week investigated as potential contributing factors. The target variable was the number of accidents involving serious and minor injuries, which were found to be significantly associated with the identified accidents in this study. © 2024 Budapest University of Technology and Economics.
