International experience, as well as previous research in the Republic of Croatia, shows that successful identification and remediation of hazardous locations results in a significant reduction in the number of traffic accidents, especially those with the most severe consequences. One of the most important steps in the process of identifying and remediation hazardous locations is the direct inspection of the location on the ground by an expert team, which in the most relevant way identifies deficiencies on the road and related equipment. Total of 117 locations have been inspected in the Republic of Croatia in the past year, which represented potentially hazardous locations on state roads, of which 61 is in located in urban areas. Based on the reviews of potentially hazardous locations in urban areas, significant data were collected on the condition of the road and related equipment, the results of which were analysed in detail and presented in this paper. Based on these results, remediation measures have also been proposed, which enable increased road safety and reduced traffic accidents.

Definition Of

Over the past few decades, the growth of the urban population has been remarkable. Nowadays, 50% of the population lives in urban areas, and forecasts point that by 2050 this number will reach 70%. Today, 64% of all travel made is within urban environments and the total amount of urban kilometers traveled is expected to triple by 2050. Thus, seeking novel solutions for urban mobility becomes paramount for 21st century society. In this work, we discuss the performance of vehicular networks. We consider the metric Delta Network. The Delta Network characterizes the connectivity of the vehicular network through the percentage of travel time in which vehicles are connected to roadside units. This article reviews the concept of the Delta Network and extends its study through the presentation of a general heuristic based on the definition of scores to identify the areas of the road network that should receive coverage. After defining the general heuristic, we show how small changes in the score computation can generate very distinct (and interesting) patterns of coverage, each one suited to a given scenario. In order to exemplify such behavior, we propose three deployment strategies based on simply changing the computation of scores. We compare the proposed strategies to the intuitive strategy of allocating communication units at the most popular zones of the road network. Experiments show that the strategies derived from the general heuristic provide higher coverage than the intuitive strategy when using the same number of communication devices. Moreover, the resulting pattern of coverage is very interesting, with roadside units deployed a circle pattern around the traffic epicenter.

The crossings of railway and road can represent a great danger, especially in the case of poor design of these crossings, lack of management measures and inadequate provision of road crossing. Such situations are common on the road network of the Republic of Serbia. Namely, more than 50% of all road crossings on state roads in the Republic of Serbia are not adequately equipped and provided with traffic signalization and road equipment. It is evident that this problem requires timely measures and finding an adequate solution in order to efficiently implement road and rail traffic and reduce the risk of negative effects. This situation also results in the occurrence of traffic accidents at road-level crossings, the number of which has not decreased over the years. In this paper, the traffic-spatial analysis of road-rail crossings on state roads in the Republic of Serbia is performed, which includes a total of 245 road-rail crossings. The analysis was conducted in order to determine the existing situation and identify deficiencies in the network, on the basis of which adequate design and management measures will be proposed to improve the existing condition.

Due to road traffic accidents, 6941 Filipinos died in 2010, and thousands more were wounded or disabled. Head and neck injuries are the main cause of death, severe injury, and motorcycle users ' disabilities. Motorcycle users make up a large proportion of those on the road who were killed. The study’s main purpose is to develop an MCU Based Motorcycle System for Optimum Road Safety with Anti-theft Capability that will help motorcycle riders to be safe while travelling in national roads. The researchers will be using the prototyping methodology where in a prototype is built according to the initial requirements gathered from the motorists themselves. The expected result of the proposed methodology is the system will be utilizing the different function of each modules to ensure that the riders will be able to detect and avoid possible danger while on the road. As a result of different literature in relation to each module, the system is expected to provide a new leap to ensure the safety of all riders here in the Philippines. Future studies will ensure the development of the system, provide testing and improve the system’s functionality depending on the test result. Due to the high increase in the number of cars and motorcycle travelling on national road, the percentage of accidents also is getting higher. In line with that, the proposed system is expected to lessen the percentage of accident by avoiding the possible cause of it.

The objective of this research is to develop a useful procedure to assess and identify risks that promote accidents by road users, with the vision of improving safety through the implementation and technical employment of operative strategies. The relevance of this proposal lies in the fact that the issue of traffic accidents is a global problem. This project is located in the mountain range of Baja California, Mexico, in the Centinela–La Rumorosa highway and integrates accidental and pavement surface condition data, geometric design performance, analysis of traffic signals, and road safety devices present on the road using geodetic techniques. It is concluded that this procedure contributes to determining risk areas that promote accidents and generate a risk reduction plan to support future decision-making that guarantees better performance for road users. Furthermore, it is highlighted that the analysis of road safety must be a permanent process for those who operate, design, and build the road system.

As the number of vehicles increases, the number of transport accidents in developing countries increases. Accidents are the second cause of death in Ghana after malaria. Pedestrian accidents remain the main problem in Ghana, as they represent the largest percentage of deaths in traffic accidents. The death rate among pedestrians was 3 times higher than among vehicle users. Insufficient lighting of roads and lack of infrastructure for pedestrians are the cause of an increased number of fatalities among pedestrians. Increasing the visibility of pedestrians on the road and increasing the emphasis on education in the field of road safety could reduce the number of road accidents involving pedestrians.

A trend of increasing traffic accidents involving vehicles has been observed, which requires proposed measures to prevent the occurrence of wildlife on risky sections of roads. Before implementing the relevant measures, it is necessary to rank the risk sections on the roads from the occurrence of wildlife. Roads pass through the natural habitats of wildlife, so with each kilometer of newly built roads and with each newly registered vehicle, the probability of a vehicle colliding with wildlife increases. The problem of increasing the number of encounters with game is expressed both at the global level and in the territory of the Republic of Croatia. Traffic accidents related to vehicle crashes into wildlife are a major problem of road safety on the road network. The paper presents an analytical hierarchical process of AHP methods, multi-criteria evaluation on the example of ranking dangerous sections from the occurrence of large game on state roads of Lika-Senj County. The AHP method is one of the most well-known methods of multicriteria analysis, which consists of goal, criteria and alternatives. The ranking of dangerous sections from the occurrence of large game on the state roads of Lika-Senj County by the AHP method includes qualitative and quantitative criteria. The AHP method of multi-criteria evaluation of dangerous stocks from the appearance of large game was presented with the software tool Expert Choice. The obtained results rank the dangerous sections from the occurrence of large game and define the priorities of their rehabilitation from the competent authorities.

In the article the authors consider general social and special-criminological measures of prevention of criminal offenses in the field of road safety. It is pointed out that, for the most part, such criminal offenses are the result of criminally unlawful negligence and arrogance. Therefore, it cannot be said that the lion's share is committed by drivers with direct intent in order to obtain socially dangerous consequences. There are still cases caused by traffic violations by pedestrians, which significantly complicates the forecasting of such illegal acts, and therefore the timely creation of precautionary measures. The author points out that conditionally all the reasons related to the violation of traffic rules can be divided into: 1) the reasons due to the negligent attitude of the driver to perform their duties on the road (intoxication, loss of attention, etc.); 2) the reasons caused by careless attitude of pedestrians to traffic rules; 3) the reasons caused by the careless attitude of employees of service centers of the Ministry of Internal Affairs to performance of the duties. Thus, the main unifying factor is the negligence of the subjects involved in the organization of traffic. It is concluded that a number of criminological strategies for the prevention of criminal offenses in the field of traffic have been successfully implemented in our country. However, most of these strategies do not meet the requirements and realities of today, and therefore the criminological picture of traffic accidents remains consistently negative. This indicates the need to revise general social and special criminological measures and means of prevention, which will not only reduce the number of such socially dangerous acts, but also improve the general criminal law and criminological statistics.

The main purpose of the article is to present how the Greek- -Macedonian naming dispute influenced the problem of implementation the international identity of Macedonia. Despite the initial problems of the government in Skopje related to determining their international identity, Macedonians managed to define the principles regarding the identification of a new state on the international stage. As a small country with limited attributes to shape its international position, Macedonia has basically been determined to seek guarantees for its existence and security in stable and predictable European international structures such as NATO and the European Union. The main obstacle for Macedonians on the road to Euro-Atlantic structures was the veto of Greece, a member of these organizations, resulting from Athens’ refusal to accept the name the Republic of Macedonia. The Prespa Agreement of 2018 gave a new impetus to the realization of the international identity of North Macedonia.
