This study explores the transportation behaviors of university students residing in dormitories in Kütahya, Türkiye, emphasizing their preferred modes for educational trips. Utilizing a Multinomial Logit model, the research analyzes the influence of socio-demographic factors, trip characteristics, and environmental perceptions on mode choice. The results indicate that public transport and walking are the predominant modes, with significant negative associations being observed between car ownership and the likelihood of choosing these sustainable options. Key findings reveal that, as trip distances increase, students are more likely to use public transport, while higher income levels decrease reliance on both public transport and walking. Male students demonstrate a higher preference for these modes compared to female students. Environmental perceptions, including feelings of safety and satisfaction with infrastructure, play a critical role in shaping transportation choices, highlighting the need for improved lighting, walkability, and public transport quality. These insights have important implications for transportation policy, suggesting that reducing private vehicle reliance and enhancing public transport services can significantly promote sustainable travel behaviors. Overall, the study underscores the importance of comprehensive transportation policies that not only enhance infrastructure and service quality but also consider environmental perceptions and safety to promote sustainable travel behaviors among university students.

: Karayolu üstyapı kaplamaları genel olarak Bitümlü Sıcak Karışım (BSK) veya sathi kaplama şeklinde üretilmektedir. Bu çalışmada düşük maliyeti sebebiyle kullanım alanı fazla olan sathi kaplamaların agrega-bitüm ilişkisi incelenmiştir. Yapılan çalışmalarda, agrega, bitüm ve karışım deney sonuçları birlikte değerlendirilmiştir. Agrega olarak kireçtaşı ve bazalt cinsi agregalar kullanılmıştır. Bitüm olarak; 50/70 ve 70/100 penetrasyonlu bitümler, katkı olarak ise; % 10 atık lastik ve %1 Polivinil Klorür (PVC) kullanılmıştır. Üretilen bütün bu farklı tipteki numuneler için sathi kaplamaların performansının ölçülmesinde kullanılan Soyulma ve Yapışma (Vialit) mukavemeti deneyleri gerçekleştirilmiştir. Deneysel çalışmalardan elde edilen sonuçlara göre, 50/70 bitüm kireçtaşı agregalarla daha iyi yapışma sağlarken, 70/100 bitüm bazalt agregalarda daha güçlü yapışma sağlamaktadır. Atık lastik ve PVC talaşları agrega ve bitüm arasındaki adezyonu artırmaktadır. Ayrıca atıklar kireçtaşı agregalarda daha iyi performans göstermektedir. Özellikle bazalt türü agregalarda düşük olan adezyonu, kullanılan atık lastik ve PVC talaşları artırmaktadır. 70/100 penetrasyonlu bitümde, bitümün kıvamından dolayı katkı olarak kullanılan atıkların homojen dağılmaları kolaylaşmakta ve bu sayede adezyon kuvvetindeki artış daha iyi gözlenebilmektedir. Soyulma mukavemeti kapsamında, atık lastik ile modifiye edilmiş olan bitüm ve kireçtaşı en iyi performansı sağlamıştır.

One or more than one vehicle in motion on the highway involving death, injury and loss events which have resulted are called accidents. As a result of increasing population and traffic density, traffic accidents continue to increase and this leads to both human losses and harm to the economy. In addition, also leads to social problems. As a result of increasing population and traffic density, traffic accidents continue to increase and this leads to both human losses and harm to the economy. In addition to this, it also leads to social problems. As a result of traffic accidents, millions of people die year by year. A great majority of these accidents occur in developing countries. One of the most important tasks of transportation engineers is to reduce traffic accidents by creating a specific system. For that reason, statistical information about traffic accidents which occur in the past years should be organized by versed people. Factors affecting the traffic accidents are analyzed in various ways. In this study, modelling the number of people killed in traffic accidents in Turkey is determined. The dead people were modelled using curve fitting method with the number of people killed in traffic accidents in Turkey dataset between 1990 and 2014. It was also predicted the number of dead people by using various models for the future. It is decided that linear model is suitable for the estimates.

With the rapid growth of the world population that is becoming increasingly the use of motor vehicles. Also, due to technological advances that have become more accessible to a case having a motor vehicle. However, these developments have led to the emergence of some problems. Especially, highways of serious accidents occurred in transportation, to investigate measures that can be taken and identification of the problem is an important issue in Turkey. First, you need to identify the individual's perception of traffic. This process is important to identify gaps in the application. This study was planned and carried out in order to measure the traffic perceptions of living in Eskisehir Province. For this purpose, a questionnaire aimed at determining demographic and socio-economic characteristics and attitudes of the individual's perception of traffic was prepared. Data sets were analysed by factor analysis known as one of the most known multivariate statistical analysis techniques. The result of analysis obtained over the dimensions, traffic perceptions of individual's in Eşkisehir Province modelled. Looking for solutions for the traffic problem in institutions of the Eşkisehir Province has obtained a series of results that could benefit in creating attitudes and behaviours about traffic.

Rapid growth in urban population, vehicle ownership, and spatial expansion places increasing pressure on urban transportation networks, necessitating a shift toward sustainable mobility solutions. Accordingly, this study examines the determinants of university students’ mode choice preferences for home-to-campus commuting in a small-scale city. The analysis incorporates socio-demographic factors, mobility resources, and travel attributes as potential influencers of mode choice. For modeling preferences, a Multinomial Logit (MNL) model was initially used to estimate deterministic effects, followed by a Mixed Multinomial Logit (MMNL) model to capture unobserved heterogeneity at the individual level. The results demonstrate that gender, vehicle ownership, and travel distance play statistically significant roles in mode choice. Crucially, the MMNL analysis reveals that while students’ sensitivity to travel time is relatively homogeneous, their sensitivity to travel cost exhibits significant unobserved heterogeneity. Moreover, the study reveals the potential for a modal shift toward sustainable options such as walking, cycling, and public transport. These findings offer valuable insights for promoting sustainable urban mobility and developing data-driven transport policies, specifically in alignment with the “Sustainable Cities and Communities” goal of the United Nations (UN) Sustainable Development Goals (SDGs).

The notable flexibility and relatively lower purchase and operational expenses of motorcycles, particularly when compared to automobiles, contribute significantly to their shares in traffic. However, the capacity to attain high speeds in the absence of a protective vehicle body raises safety concerns, necessitating an examination of the factors influencing motorcycle accidents. Understanding these factors is crucial for implementing precautions to mitigate the severity and frequency of accidents. In this study, we explore the relationships among carriageway hazards, weather and lighting conditions, seeking to understand their influence on the frequency of motorcycle accidents. The analysis is based on a dataset encompassing motorcycle accidents in Great Britain over the past five years. The study found that motorcycle accidents are more likely during daytime and fine weather conditions when a carriageway hazard is present, especially with objects on the road. The conclusion underscores the importance of clean and divided roads, monitoring parked vehicles, and adopting technology for hazard notification.
