Introduction of a New Variable and the Problem of Complexity in Determining Impact Speeds in Vehicle–Pedestrian Accidents

Diána Sarolta Kiss Csaba József Májer

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-08-15

Volume: 53

Issue: 4

Page Range: 381-388

Description:

Reconstruction and analysis of road traffic accidents represent an inherently complex task. This is especially true for one of the most significant accident categories, vehicle-pedestrian collisions. Forensic traffic and vehicle technical experts must determine the relevant impact speeds in virtually all cases, based on a wide variety of objective traces. The most relevant evidence and information can be obtained on-site within a limited period following the occurrence of the accident. These indispensable sources of information cannot be reproduced later or can only be reproduced to a very minimal extent. Therefore, it is essential to uncover as many traces at the accident site as possible and as soon as possible. In certain cases, the so-called rapid expert calculations may need to be performed on-site. In this paper, we seek solutions related to these rapid calculations and to facilitating the determination of speeds that play a critical role in vehicle-pedestrian accidents. The proposed approach may simplify the daily work of forensic traffic and vehicle technical experts.

Age-friendly Transport: Traffic Safety for All

Balázs Horváth Diána Sarolta Kiss Csaba József Májer

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2024-01-01

Volume: 52

Issue: 3

Page Range: 209-212

Description:

The elderly make up an increasing percentage of the European population and, with it, of the Hungarian population. Modern society is built around mobility. These two factors together lead to an increasing proportion of elderly drivers on the roads. Given the high proportion of people with chronic neurological conditions (stroke, Parkinson's disease, dementia), particular care should be taken to regularly check their fitness to drive. At present, there is no standardized, well-established protocol for the objective assessment of fitness to drive in the case of these diseases. Our paper discusses this matter.

The Role of Public Transport in Transport Safety and Public Safety

Agoston Winkler Diána Sarolta Kiss

Publication Name: Eurasia Proceedings of Science Technology Engineering and Mathematics

Publication Date: 2023-01-01

Volume: 23

Issue: Unknown

Page Range: 505-512

Description:

Public transport has a significant role in sustainable urban transport including the reduction of congestion, noise and air pollution. The main purpose of this paper is to present other important impacts of public transport i.e., the improvement of transport safety and public safety, too. Public transport is one of the safest transport modes according to the indication numbers in traffic accident and injuries. This phenomenon is illustrated through literature research as well as statistical data. Further opportunities are presented with a case study based on the transport system of the city of Győr, especially the positive impacts of the possible expansion of night public transport services. The severity of traffic accidents at nights is significant, and the enhancement of public safety is outstanding. Marketing is one of the most important tools for attitude formation, the paper contains some suggestions in this regard as well as in order to promote the goals above.

Impact of Iron Loss on Performance of Speed Sensorless MRAS Estimator for Induction Machines

Krisztian Horvath Diána Sarolta Kiss

Publication Name: 2022 22nd International Symposium on Electrical Apparatus and Technologies Siela 2022 Proceedings

Publication Date: 2022-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

In this work, the impact of iron loss on speed estimation performance of the conventional rotor flux error-based model reference adaptive system (MRAS) estimator is investigated in case of induction machines (IMs). In addition, two improved MRAS-type estimators are proposed to reduce the estimation error caused by iron loss. The first approach takes into account iron loss resistance by its nominal constant value. But in the second case, iron loss is frequency dependent. All three estimators are compared by simulations. The results show that the MRAS estimators with iron loss compensation can reduce the speed estimation error and the frequency dependent iron loss compensation method provides the highest accuracy.

Comparison of self-reported and observed road safety performance indicators

Tamás Berta Diána Sarolta Kiss Péter Holló

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2018-06-05

Volume: 46

Issue: 3

Page Range: 117-121

Description:

The first concept of road safety performance indicators was published by European Transport Safety Council, Brussels in 2001. Hungary has long and reliable time series of safety belt wearing and child safety seat usage rates in passenger cars. These rates are based on real roadside observations and representative sample, meeting the requirements of international road accident databases. The methodology of the data collection has been further developed during the recent years, but we paid attention to the possibility of comparison with the earlier data and consistent analysis of time series. Although the roadside observations could not have been organized in each year, the trends can be seen relatively well. Our initial hypothesis was that the self-reported data always show a bit "better" picture about the driving behaviour than the observed ones, since the people are not sure that their data will be handled in an anonym way. Based on these results we can say that the ESRA results are relatively good estimations of the real safety belt wearing rates.

What Kind of Steps Shall we Implement from the GDE Matrix into Driver Education of Hungary to Decrease Risk of Accident among Novice Drivers?

Publication Name: Transportation Research Procedia

Page Range: 3821-3828

Description:

It is a well-known problem that in every year there are 27000 deaths on the roads. The European Union has determined the target of the killed people of road accidents and it means 50% percentage decreasing until year of 2020. Until 2050 no one can die in road accident. (White Paper, 2011). Young people percentage in our society is about 10%, but the participation in fatal accident injuries is almost 27%. It is a significant difference, and we have to do against the problem. States of European Union has different kinds of driver education with diverse tools, methods and programs. There is a matrix (dubbed Goals of Driver Education) which summarized essential elements and hierarchical levels of driver behavior to make driver education more effective (decreasing novice driver's accident risk). Driver education of some countries is based on this theory. In Hungary there were a lot of changes in driver education causes decreasing trend in the number of passed exams. To find an optimal solution to make our education more traffic safety-oriented I try to reflect on the main missing points, which we should implement to our driver education so novice drivers could be able to estimate their skills and to have a realistic self-assessment.
