The present research describes the development and validation of a self-reported instrument that measures the determinants of pedestrians’ intention to violate traffic rules, based on the theory of planned behaviour. Moreover, the research deals with the analysis of the predictive validity of an extended theoretical framework of the theory of planned behaviour in relation to pedestrians’ intention to violate. Based on the quota sample, adult pedestrian respondents (n = 383) completed a questionnaire assessing the relevant variables. Valid and reliable scales were developed, and they measure subjective, descriptive, normative, and personal norms, cognitive and affective attitudes, perceived behavioural control, habit formation, and behavioural intention concerning pedestrians’ misdemeanour. Hierarchical regression analysis indicated that all components, except descriptive norms, were significant simultaneous predictors of pedestrians’ intention to violate. The most powerful predictor is the personal norm. Overall, the findings considerably support the concept of the extended theoretical framework of the theory of planned behaviour.

The paper analyzes the changes in the number of traffic accidents fatalities in the Republic of Serbia. The statistical significance of the change in the number of fatalities in relation to the period before and after the application of the new Law on Traffic Safety was tested. The results indicate the significance of the change in the total number of fatalities, fatalities of drivers of passenger cars, motorcyclists and mopedists, fatalities of male persons and young people.

The transportation of dangerous goods (DG) presents significant risks due to their hazardous chemical properties, which, in the event of an accident, can have detrimental effects on the environment, public health, and infrastructure. Although the transport of such materials is generally prohibited, the growing demand for DG transportation over long distances necessitates compliance with stringent international regulations (e.g., ADR, RID). In urban areas, where transport routes may intersect with residential zones, incidents involving DG can lead to severe consequences, including fatalities, environmental damage, evacuation of local populations, and disruptions to traffic. To mitigate these risks, effective risk management is essential, encompassing analysis, assessment, and reduction strategies. Risk assessment for DG transport can be conducted using various quantitative and qualitative methods, with this study employing the Areal Locations of Hazardous Atmospheres (ALOHA) software and Geographic Information System (GIS) tools for both risk evaluation and visualization. The study area is located in the capital of Montenegro, specifically within the Stari Aerodrom District. This research focuses on evaluating the potential impact of DG transport incidents in this area and the consequences of hazardous material releases in confined spaces. Three specific DGs—benzene, chlorine, and methane—are considered, each presenting distinct environmental, health, and property-related risks. Chlorine is selected as the worst-case scenario, with its impact radius extending approximately 10 km from the release point. The primary objective of this study is to provide a comprehensive assessment of the risks associated with DG transportation, highlighting the importance of safety improvements and effective emergency response strategies. The findings underscore the need for enhanced safety measures during transport and the development of more robust emergency management frameworks for DG-related incidents.

The exogenous characteristics of traffic participants, such as: alcoholism, fatigue and psychoactive substances, have a significant impact on a safe behaviour in traffic, especially the motor vehicle drivers. In that sense, they represent the factors that can directly influence the unsafe behaviour in traffic. The influence of the exogenous characteristics on a safe behaviour of traffic participants has been analysed on the basis of the statements in documents as well as the results of numerous empirical studies. For the purposes of this paper, there have been selected and analysed the statistical data on the influential factors of traffic accidents for the period from 2010 to 2019 in Republic of Serbia. After reviewing the statistical data, both a qualitative and quantitative content analyses were performed. In addition to the statistical method, there were also used the content analysis methods, empirical method, descriptive method, comparative methods, as well as deduction and induction methods, in order to analyse the trend and presence of these influential factors of traffic accidents in Republic of Serbia. The statistical data being processed in this paper, originated from the database of the Traffic Safety Agency of Republic of Serbia. The results of the research show the extent to which the exogenous characteristics affect a safe behaviour of traffic participants, as well as the severity of the consequences of traffic accidents. Observed individually, the listed characteristics have a different intensity of influence on a safe behaviour in traffic. In this regard, from the external characteristics of traffic delinquents, the most common is the drunk driving as an influential factor, which especially affects the severity of traffic accidents in Republic of Serbia.

Enforcement of radical legislative measures in order to improve traffic safety in the Republic of Serbia, which are implemented for some time, should result in a reduction of the rate of the traffic delinquency. This paper analyses trends in traffic delinquency rates in the Republic of Serbia with the aim to show trends of traffic delinquency rates by looking at the total number of traffic accidents and traffic offenses, the structure of traffic delinquency rates, as well as the share of traffic offenses within the overall crime in Serbia for period 2014-2018. The aim of this paper is to analyse the statistics, to obtain the right picture about existing situation, trends and structure of traffic delinquency, as well as about the effectiveness of preventive and repressive measures implemented, as well as the possible need to take further steps towards combating the traffic delinquency.

The transport of dangerous goods poses a significant challenge for the industry, given the potential risks to safety and the environment. This paper analyzes key aspects of regulation and training that affect the efficiency and safety of this sector. Based on a literature review, a survey was developed and conducted in 2023 among 204 respondents, professionals in the field of dangerous goods transport in Serbia. The survey was distributed through electronic channels, allowing for broad access to various industry participants. It encompasses questions that describe six constructs: assessment of the dangerous goods transport environment, legal framework and regulatory familiarity, vehicle classification and documentation, training and certification, vehicle inspection and maintenance, and statistics and procedural aspects. The survey results indicate varying levels of satisfaction with regulation and training. According to the respondents, 35% rated the regulatory process for obtaining a professional competence certificate for dangerous goods advisors as "very good," while 24.8% rated it as "satisfactory." Regarding the training content for certificate renewal, 29.1% of respondents rated the content as "very good," but 10.2% expressed dissatisfaction, suggesting a need for improvement in training programs. The analysis of administrative costs reveals that only 5.8% of respondents rated these costs as "excellent," indicating a need for strategies to reduce costs to enhance accessibility and competitiveness in the dangerous goods transport sector.
