Trends of globalization very often cause the emergence of phenomena that asymmetrically affect the overall sustainability of the transport system. In order to predict certain situations and potentially be able to manage the transport system, it is necessary to manage risk situations and traffic safety in a timely manner. This study has conducted an investigation which implies defining the level of safety of a total of nine sections of two-lane roads. The main aim of the paper is to create a new multiphase model consisting of CRITIC (The CRiteria Importance Through Intercriteria Correlation), Fuzzy FUCOM (Full Consistency Method), DEA (Data Envelopment Analysis), and Fuzzy MARCOS (Measurement Alternatives and Ranking according to the COmpromise Solution) methods for determining the level of traffic safety on road sections under the conditions of uncertainty. In order for the created model to be adequately applied, eight parameters were created, and they were classified through four inputs and four outputs. To calculate the significance of the inputs, the CRITIC method based on the symmetric correlation matrix was used, and taking into account the nature of the outputs, the Fuzzy FUCOM method based on averaged values using the fuzzy Bonferroni Mean (BM) operator was applied to determine their weights. To determine the degree of safety, the DEA model was created. After that, the Fuzzy MARCOS method was used in order to determine the final ranking of the remaining five sections of the road network. Finally, the verification of results was performed through three phases of Sensitivity Analysis (SA).

Identification of key indicators that cause safety challenges and vulnerable roads is crucial for improving traffic safety. This paper, therefore, entails to the development of a novel multiphase multicriteria decision-making (MCDM) model to evaluate the vulnerability of urban roads for traffic safety. This was conducted by using data from 17 important roads of a South African city and combining several methods such as CRiteria Importance through Intercriteria Correlation (CRITIC), data envelopment analysis (DEA), and measurement of alternatives and ranking according to compromise solution (MARCOS). Taking the elements of the DEA method, two new approaches for calculating the weights of criteria, the DEA-1 and DEA-2 models, were formed and integrated with the CRITIC method to obtain the final values of criteria weights. The MARCOS method was applied to evaluate 17 alternatives, for each direction separately. The aim of developing such a model is to use the advantages of obtaining objectivity of criteria weights through linear programming and correlation of values of the collected data. Also, the MARCOS method, as one of the newer and applicable methods, provides additional significance. Extensive sensitivity analyses were conducted to validate the model. The findings suggest that there are a certain number of roads that have a high level of safety for both directions, as well as a group of risky roads, which need traffic improvement measures. Thus, the results indicate that the model is sensitive to various approaches and can prioritize vulnerable roads comprehensively based on which safety measures can be taken.

The article explores the driving conditions for determining the demand of drivers of vehicles for the movement of roads, the road conditions of which should ensure this demand. The object of the study is automobile international and national transport corridors. When optimizing the management of the complex transport system «International, national and local traffic flows - Automotive International and National Transport Corridors» (MNMTP-AMNTC) can be sought to achieve different goals (criteria of optimality), and, depending on these goals, consider the different tasks of optimal management. On road transport, including in this concept of the system of communication routes (highways), the following tasks are the most important: ensuring the least time of communication at limited road costs; - ensuring the specified time of communication at the lowest road costs; - ensuring the lowest transport costs at a limited level of road costs; - ensuring the lowest road costs at a limited level of transport costs; - ensuring the maximum possible level of traffic safety at a limited level of road costs; - ensuring the required level of traffic safety at the lowest road costs; to achieve a minimum of road costs, provided that the specified volume of traffic (traffic), the specified speed and the necessary safety of traffic; ensuring maximum road capacity at a limited level of road costs. According to its parameters, the MMMTP-AMNTC refers to complex systems, the main characteristics of which are: efficiency indicator; stability; obstruction; Reliability. The newest approach of the «Traffic Triad» will allow to evaluate the functioning and ensure the rational management of any transport system with a focus on meeting the needs of users of highways - road users.

Undertaking the subject of the application of telematic systems to improve the safety of road transport is caused by the increase of the mobility of the society, their transport needs, which in effect leads to the multiplication of the number of vehicles on the roads. The low level of construction of new roads and modernization of the existing ones is conducive to the occurrence of transport congestion, the number of accidents and road traffic difficulties, and has a negative impact on the natural environment. In the era of modern society, methods are sought that would minimize negative effects in the transport system, thereby increasing road safety. The purpose of this article is to analyse the use of Intelligent Traffic Light in the aspect of road safety. Traffic safety at intersections is reflected in indicators of dangerous situations with the participation of road users in its area. Hence, the selection of the research method and the place of the tests carried out. Implementation of telematic systems supports the construction of a secure road transport network. The authors of the article focused on the analysis of traffic hazards and their consequences in the form of wounded and dead people. In addition, the topic of safety in the road transport system was addressed very precisely, where it was discussed in terms of operation, economic, technical and environmental protection.

Accident Data

The majority of traffic safety evaluations in the world generally have been conducted by colecting historical accident data. The data will then being analyzed using risk prediction models or before-after study that required an exact and reliable data. Meanwhile, the availability of accident data is rare where the rest actually consist of near-crashes and abnormal behaviour, which is mostly underreporting and lack of detail concerning the behavioural and situational of the event. Therefore, traffic conflict technique, is needed to assess traffic safety as another approach rather than waiting for several years until a number of accidents happen in a certain area. Hence the aim of this study is to make a safety evaluation towards a specific intersection in Hasselt Belgium using traffic conflict technique. The observation of conflict (near crashes) was carried out in intersection of Manteliusstraat – Dorpsstraat – Thonissenlaan in the Hasselt, Belgium. In order to differentiate slight conflict and serious conflict, the TA-value (Time of accident) was defined based on the estimated speed of the road user and estimated distance from the road user when conflict occurred. From the observation, it was found that the conflicts between car and pedestrian were the most frequent conflict, with 50% of the total conflict, and that the conflict between car with car and the conflict between car with cyclist were high in terms of severity level based on the TA-value. By taking these into consideration, it can be concluded that unsafe crossing for pedestrian and cyclist, different speed, and peak hour traffic were the causes of conflict. Therefore, it was concluded that traffic conflict technique can be used to assess and measure traffic safety in a certain road segment. Furthermore, in term of safety, the Manteliusstraat – Dorpsstraat – Thonissenlaan intersection should be modified with some alternatives; signalized intersection with toucan crossing and traffic control devices improvement

ABSTRACT The use of studded tires has been a subject of controversy from the time they came into market. While studded tires contribute to traffic safety under severe winter conditions by increasing tire friction on icy roads, they also cause damage to the road surface when running on bare roads. Consequently, one of the main challenges in studded tire development is to reduce road wear while still ensuring a good grip on ice. Therefore, a research project was initiated to gain understanding about the mechanisms and influencing parameters involved in road wear by studded tires. A test method using the institute's internal drum test bench was developed. Furthermore, mechanisms causing road wear by studded tires were derived from basic analytical models. These mechanisms were used to identify the main parameters influencing road wear by studded tires. Using experimental results obtained with the test method developed, the expected influences were verified. Vehicle driving speed and stud mass were found to be major factors influencing road wear. This can be explained by the stud impact as a dominant mechanism. By means of the test method presented, quantified and comparable data for road wear caused by studded tires under controllable conditions can be obtained. The mechanisms allow predicting the influence of tire construction and variable operating conditions on road wear.
