Even with increasing road accidents, crash data at a particular location is mostly underreported. Hence, using the Traffic Conflict Technique (TCT) with Surrogate Safety Measures (SSMs) to evaluate traffic safety instead of accident data has gained significant attention among researchers in India. However, the traffic existing in the country is more complex and diverse than most of the developed nations around the world. This led the researchers to modify the existing methods and propose new methods to address the heterogeneity of the existing mixed traffic. The current study formulated six research questions to guide the review process. Since the number of studies in the area of research is increasing rapidly, there is a need to study the current state of the art in the country. Hence, the paper critically reviewed thirty-three studies conducted in the area of research in Indian conditions, including their findings and limitations.

In Kuwait, the increasing use of motorcycles, particularly for delivery services, has raised crash risks, highlighting the need for updated safety measures. This study analyzes the driving behavior of motorcyclists and car drivers, focusing on road usage, traffic violations, and licensing while identifying key factors contributing to motorcycle crashes through surveys, interviews, and historical records. A busy area of the city was chosen as the research site due to its high concentration of restaurants and heavy traffic from delivery motorcyclists, customers, and other road users. Data was collected from interviews with 103 motorcyclists, an online survey of 300 car drivers, and publicly available open-source national data. Advanced statistical methods were used for analysis, including the Vector Autoregressive Model, Structural Equation Modeling, and Principal Component Analysis. The findings revealed that motorcycle-related road crashes are influenced by factors such as the motorcyclist's gender, spatial awareness, perceptual challenges, and familiarity with motorcycle positioning. Conversely, crash frequency is associated with the driver's experience, right-of-way violations by other road users, traffic violations by motorcyclists, and road conditions. To mitigate motorcycle-related road crashes, the study recommends the development of an Exclusive Motorcycle Lane with an optimal width of 1.855 m in the selected research site. This step has the potential to significantly improve road safety, reduce accidents, and save lives, contributing to safer urban mobility in Kuwait. Similar measures could also be implemented in countries with a high risk of motorcycle-related road crashes.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"49 2","pages":"Pages 169-179"},"PeriodicalIF":3.2,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143823578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It utilizes data from two surveys conducted in Hau Giang, Vietnam in 2022. The first investigation surveyed 351 participants to elicit the motorcyclists' behavioral beliefs and control beliefs when making crossing maneuvers that complied with traffic rules (complying maneuvers, CM), and the second investigation interviewed 260 respondents to elicit motorcyclists' beliefs when making crossing maneuvers that violated traffic rules (illegal maneuvers, IM). By applying the Structural Equation Modeling approach, the results reveal that the intention of motorcyclists to perform crossing maneuvers (CMs) is influenced by facilitating circumstances, subjective norms, and descriptive norms. In contrast, the intention to perform improper maneuvers (IMs) is driven by advantage beliefs, descriptive norms, facilitating circumstances, subjective norms, and driving situation awareness. Additionally, risk perception directly affects motorcyclists' performance of CMs, while near-miss incidents related to IMs are directly influenced by facilitating circumstances and perceived risk. These findings suggest that reducing improper maneuvers and promoting safer road-crossing performance can be achieved through targeted safety intervention strategies. Such strategies could include addressing the consequences of advantage beliefs regarding IMs and enhancing riders' situation awareness and risk perception through driver education and training programs.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"49 2","pages":"Pages 114-126"},"PeriodicalIF":3.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
