Cycling safety management is particularly important due to the increasing use of this mode of transport and increasing car traffic flows. Cyclists—travelling on roadways or sharing the space with pedestrians—are exposed to considerable risks for their safety, as well as for the safety of other road users. Comprehensive and effective management of bicycle traffic safety is therefore essential for the protection of this group of road users. The article presents procedures, the implementation of which is aimed at increasing the safety of cyclists and effective implementation of measures to achieve that. The analyses aimed at the selection of appropriate measures and solutions to improve safety of cyclists in the road traffic have been presented. The procedures include: Selection of devices and measures, risk assessment and estimation of the potential to reduce the risk of collisions/accidents involving cyclists, selection of investment measures and devices reducing the risk of cyclists and other road users, implementation methods and monitoring of selected measures reducing the risk of collisions/accidents involving cyclists. The proposals contained in the article fill in the gap existing in this area of knowledge. The analyses conducted and the presented results show that the construction of infrastructure for cyclists is not the only way to improve the safety of this group of road users. Due to the high costs and deficit of the road surface in the road-street cross-section—other forms of measures in this area should also be analyzed.

The groups of participants of the pedestrian and automobile flows, whose actions cause the greatest danger to the occurrence of conflict situations in the zone of unregulated transition, are identified. The factors determining the likelihood of a traffic accident at an unregulated transition are systematized, for which probability estimates of the occurrence of road traffic accidents are calculated. As an estimated parameter, the hazard coefficient of a conflict point of an unregulated transition is proposed, which is determined by the ratio of the probability of a traffic accident in the real-time hourly interval to the average annual probability of a traffic accident reduced to the hourly interval. The dependences of the hazard ratio of an unregulated transition are established on the most significant factors: the speed mode of transport in the area before the transition and the state of the road surface.

Road traffic fatality is rated as one of the ten causes of death in the world and with various preventive measures on a global level, this prediction is only placed on flat terrain and didn’t reduce. Nevertheless, road users’ communication is an essential key to traffic safety. This communication, be it formal or informal between the road users is an important factor for smooth traffic flow and safety. Communication language on roads can be categorized into; formal device-based signal (formal signal), formal hand signal (formal signal), informal device-based signal (informal signal), and informal gesture-based signal (everyday signal). However, if the intent of the message conveys is not properly understood by the other road user, mistakes and errors may set in. Overall, the formal signal is based on explicit learning which occurs during the driving training and the license testing process and the informal, implicit learning occur during the actual driving process on the road unintentionally. Furthermore, since the informal signal is not a prerequisite to driving or taught in driving schools, novice drivers are clueless and thus, might have contributed to errors and mistakes which leads to traffic fatalities. Therefore, this study seeks to document the informal means of communication between drivers on South African roads. Consequently, a qualitative semi-structured interview questionnaire would be used in the collection of informal signals, which were predominantly used on South African roads from driving instructors and thereafter, a focus group of passengers’ car, commercial and truck drivers will be used to validate the availability and their understanding of these informal signals using a Likert-type scale for the confidence level. In conclusion, the information gathered from this study will help improve road safety and understanding of road users especially drivers on the necessity of communication and possible adaptation for other developing countries.

The article is devoted to the author's concept development of the short-term road safety management on the federal roads in Russia. The results of development the rule for calculating hazard level depending on the road accidents risk are presented. The mathematical basis of the research is fuzzy modeling. The main stages of modeling are performed using the FisPro software. The concept of acceptable risk has been implemented based on the target values of state programs to improve traffic safety. The developed rule base is the basis for determining the hazard level, which can be the basis for calculating the main parameter of short-term road safety management – the hazard level.

The article is an attempt to present the two modern concepts of safety management systems. The first is the sunflower pyramid used especially in Europe, the second is the ISO 39001 standard (Road Safety Management System) of international scope. The idea and possibilities offered by use of both concepts of safety management, as well as an attempt to assess the impact of their actions on decrease in fatalities in selected EU countries, were presented. As a result of the conducted analyses, a downward trend was noted as to the number of certificates issued for compliance with the ISO 39001 standard in the world, which may indicate an appearance of the more adequate management systems, or other tools or concepts to improve the road safety, or inadequate education society and low level of awareness in this area of stakeholders, including politicians, scientists, producers, drivers (professional and reliable), as well as other road users, including unprotected ones.

IntroductionRoad traffic injuries (RTIs) are the leading cause of preventable death in Qatar; consequently, the country has participated in the Decade of Action for Road Safety (DoARS) coordinated by the United Nations Road Safety Collaboration (UNRSC). Its goal is to reduce the number of road traffic deaths and injuries by 50% by 2020, by implementing road safety activities, in the areas of road safety management, safer roads, safer vehicles, safer road users and postcrash response, the five pillars. This study will evaluate the initiatives and programs implemented in Qatar, during the initial period of the DoARS.MethodsA retrospective process evaluation of the compliance of national road safety activities in Qatar, with global indicators for the DoARS set by the UNRSC was conducted. A web-based online and electronic media search, in both official languages of Qatar: Arabic and English, for data and information on completed or ongoing road safety initiatives and activities implemented in Qatar, from January 1, 2011 to December 31, 2016, was supplemented by personal consultation with relevant stakeholders in the road safety field.ResultsThere was complete compliance for Pillars 1 (Road Safety Management) and 2 (Safer Roads), whereas Pillars 4 (Safer Road Users) and 5 (Postcrash Response) met most of the DoARS indicators, and Pillar 3 (Safer Vehicles) complied with none.ConclusionQatar must continue to implement its present road safety activities within the Action Plan for the DoARS to achieve its goals by 2020. It must, however, implement more new efforts to require safer vehicles and make road users safer, especially those at the highest risk, that is, young drivers, occupants and workers.Level of EvidenceLevel IV.

Stable and slidable roofs of the semitrailers are usually characterized by low weight and easy handling, which equals directly into comfort of use, longevity of the system and the time needed to open or close. However, not always an operational advantages of roofs go hand in hand with their durability, especially in the snowfall situation or sudden changes of the road lane by a set of vehicles: a truck tractor – a semitrailer. The analysis of homologation regulations shows that today there are no precise requirements and physical testing / strength methods for assembled roofs of the semitrailers as components. The test methods for complete vehicle bodies (including the roof), which have destructive nature, are described in European standards, e.g. EN 12642:2017 "Securing of cargo on road vehicles – Body structure of commercial vehicles – Minimum requirements" [6], internal German regulations, e.g. VDI 2700:2004 "Securing of loads on road vehicles" [8] or Directive DCE 9.5:2008 ”Load security for transportation of load containers on utility vehicles in road traffic” [7]. A non-destructive, possible to perform, testing method for the roof as a component - is calculation method. The results of the performed tests allow to conduct development works over improving the vehicle’s system security (including the introduction of new semitrailers roofs design solutions and verification of existing ones). The carried out strength tests give possibilities to optimize and adapt the roofs to the transported loads, e.g. stable lifting roofs used in transport of divisible loads, or sliding roofs used in the transport of non-separate loads. The strength testing of the semitrailer’s roofs is highly justified from the point of view of securing the load and safety of passengers, drivers and other road users primarily. The requirements and limitations of the mentioned testing methods are not - in the authors opinion - 100% of realistic and possible deformation during the real vehicle’s road traffic. On the other hand, the cited documents exists as recognized regulators in the international arena of the road traffic legislation. The work’s aim is demonstrating the benefits of using reinforced roofs in all types of the semitrailer’s bodyworks.

AbstractThe article presents the application of the GWR (Geographically Weighted Regression) model to the description of differences in the level of road traffic safety in individual counties on the example of the Kuyavian-Pomeranian Voivodeship. The GWR model developed for counties, taking into account the diversity of NUTS 3 regions, can be a helpful tool for traffic safety management in voivodships and lower administrative units, and such an approach has not yet been applied.

Because the current research on traffic level has not yet been achieved classification, it cannot timely and effectively provide the basis for the public transportation and safety management of the traffic control department. Introduce traffic safety index based on toll data to evaluate freeway traffic levels. Firstly, combined with the relevant indicators of traffic engineering, put forward the concept of freeway traffic safety index; secondly, calculate the traffic safety index by analyzing real-time toll data; finally, in order to improve the accuracy of evaluation, have an optimization of traffic safety index definition. Application on the Beijing-Hong Kong-Macao freeway shows that traffic safety index can be combined with monitoring data to evaluate the condition of road sections and the road network, and its historical data can be used to predict the road traffic conditions, and provide effective guidance for freeway traffic safety operation.

Road accidents are one of the leading causes of death in the world, particularly among young people. Excessive speed is one of the main risk factors in road traffic safety, increasing accident probability and affecting accident severity. Experimental research of the traffic calming measures allocation effect on the driving speed is presented in this paper. The research has been carried out on two aspects. The first one with respect to the mean speed and the second one regarding instantaneous speed. However, the paper is not only restricted by the above research. Standardized survey interview and questioning, a survey of public opinion, was carried out to find out the road users’ opinions about the need for traffic calming measures and speed control measures. Finally, the authors presented their insights and recommendations for the installation of speed humps and gateways and their optimum spacing.
