Drivers’ response time means that drivers act after a judgment is made when an emergency action signal is needed. Drivers have different feelings while driving, and the response time to sudden situations differs. The main purpose of this study was to verify whether the mean reaction time of professional drivers is at the level of one second, which is the value usually used for practical purposes, and to verify the impact of age on the reaction times of drivers. Two different studies with a total of 120 participants—professional drivers—were conducted on the simulator, with 116 drivers participating in the first experiment and four drivers participating in the second experiment using eye-tracking technology. The determination of the mean reaction time was realized using statistical tests. The evaluation of the impact of age on the reaction time of professional drivers was carried out using statistical testing, a regression model, and clustering. The results of this study can be immediately used in practice for professional drivers, as the mean reaction time is usually used as a benchmark in several calculations in transport, for forensic and educational purposes, and for planning traffic and modelling different traffic situations.

The social legislation is a current and political issue in the field of road freight transport. Working conditions for drivers in the EU (including Switzerland, Norway, Liechtenstein, and Iceland) are governed by Regulation (EC) No 561/2006. Regulation (EC) No 561/2006 - known as the Driving Time Regulation - lays down rules on driving times, breaks and rest periods for drivers of lorries and buses to improve working conditions and road safety. A number of new amendments to this regulation were adopted on 15 July 2020. The aim of this paper is to present the most important changes adopted compared to the previous version of the Regulation. The paper deals with the adopted changes in the following areas: weekly rest periods, secure parking areas, vehicles which are transported by ferry or train and exceeding driving time which may jeopardize road safety. The main purpose of this paper is to summarize and inform researchers, practitioners and all interested parties about the adopted changes in the Regulation, as well as the transport companies responsible for planning and scheduling the working time of drivers and also for preventing unpleasant experiences resulting from possible compliance with the conditions of the Regulation. The adopted changes in Regulation are also illustrated in the figures and table to better understand the differences.

This article discusses the importance of driver behavior analysis in improving public transportation safety. It specifically focuses on the case of Istanbul Metropolitan Municipality Istanbul Electricity Tram and Tunnel Operations General Directorate (IETT), which operates a large number of public vehicles in Istanbul, including buses, Metrobus, Beyoglu nostalgic tram, and Karakoy tunnel funicular system. The article highlights various technologies IETT uses to analyze driving behavior, such as GPS data analysis, bus telemetry data analysis, and driver behavior data analysis. It also presents an analysis of driver violation data obtained from a driver motion analysis system used by IETT to detect violations. The data shows that the most violated rule is seat belt fastening, followed by distraction, drowsiness, and other violations. The article suggests that analyzing driver behavior data can help identify areas where driver behavior can be improved, reduce the risk of accidents, and improve overall safety.

Purpose-The purpose of the research is to examine the sustainability reports of retail trade and food manufacturing companies and to evaluate the environmental performances of the companies in the sustainability reports within the framework of the criteria published by the Global Reporting Initiative (GRI). In this study, retail trade and food manufacturing companies were examined considering the environmental importance of the sector, the intensity of legal regulations regulating the sector's relationship with the environment, the professional perspective of the sector on sustainability reports, and the increasing awareness of the employees in the sector.. Retail trade and food manufacturing companies, which are in the top 5 in terms of net sales in the 2021 Fortune 500 list for Turkiye, were included in the evaluation due to the fact that the published sustainability reports contain intensive information and there is a time limit for the study. It is aimed to rank the companies under consideration in terms of environmental performance within the scope of their sustainability reports for 2020 and 2021. Methodology- The environmental performance of companies was evaluated through multi-dimensional decision-making techniques such as AHP and TOPSIS. Findings This paper has revealed changes in the rankings of companies in environmental and economic performance evaluation. The best environmental performance based on the results of the calculation is the ULKER Bisküvi San.Tic.A.Ş. the lowest company Anadolu Efes Biracılık ve Malt San. A.Ş. Conclusion- Sustainability performance gains importance as an important indicator for companies.It is thought that the results obtained in this study will be beneficial to other companies operating in the retail trade and food manufacturing sector but have not published a sustainability report, and to companies planning to prepare a sustainability report. Transparent and detailed preparation of sustainability reports is one of the issues to be considered for performance measurement.

Purpose- This study examines the dynamic relationship between financial development and green logistics in emerging OECD countries by applying a panel ARDL approach. Inspired by Özaytürk and Özekenci (2024), the main goal is to understand how financial development contributes to green logistics transformation in economies with evolving financial infrastructures. Methodology- The analysis covers nine emerging OECD countries (Turkey, Poland, Mexico, Hungary, Slovakia, Colombia, Latvia, Lithuania, and Estonia) from 2002 to 2021. The dependent variable is the ratio of transport-related CO₂ emissions to GDP, used as a proxy for green logistics performance (Fan et al., 2022). Financial development (FD), foreign direct investment (FDI), and trade openness (TO) serve as explanatory variables. Panel ARDL modeling is employed to capture both long-run and short-run effects, with cross-sectional dependence tested using Pesaran CD (2004), stationarity examined via Levin-Lin-Chu (2002), and common factor structure assessed using PANIC (Bai & Ng, 2004). Findings- Empirical findings suggest that financial development has a statistically significant and negative effect on CO₂ emissions in the long term, confirming its role in supporting green logistics (Jinru et al., 2022; Xu & Li, 2024). In contrast, FDI and TO do not exhibit significant long-run effects. The short-term impacts of all variables were found to be statistically insignificant, highlighting the crucial importance of institutional quality and environmental governance (Agyabeng-Mensah & Tang, 2021; Barut et al., 2023). Conclusion- The study underscores the pivotal role of financial development in facilitating green logistics by easing access to environmentally friendly investments. However, financial mechanisms alone are not sufficient; complementary policy tools such as strong environmental regulations, institutional capacity, and governance reforms are necessary to ensure sustainable green logistics transitions in emerging economies (Xu & Li, 2024)..
