This research aims to examine the traffic noise levels and to improve the performances of the Calculation of Road Traffic Noise model (C.R.T.N.) by applying the statistical multiple linear regression approach. Research methods included traffic noise level measurements with a noise measuring device in an urban area, using a sampling method in different periods. An evaluation of the measured data and prediction results was performed. Based on the predicted values of the C.R.T.N. model and coefficient of determination (R2), multi-linear regression was carried out to determine statistically significant parameters. The obtained multi-linear regression equation defined a new form of C.R.T.N. model. When applying the new improved version based on the C.R.T.N. model, higher accuracy of prediction is achievable. It can be seen that by applying multi-linear regression, the obtained prediction values are acceptably equated with field measurements in the chosen research environment. So, in this way, the differences between the predicted values of the noise level and the values measured in the field were minimized. Finally it can be concluded that when applying the new improved version based on the C.R.T.N. model, higher accuracy of prediction is achievable.

Today's age of unbreakable connections between physical and digital components requires large amounts of information and data to generate adequate decisions and achieve more efficient management systems. The era of the Fourth Industrial Revolution known as Industry 4.0 primarily highlights digital technology aimed at integration with the Internet of Things (IoT), access to large amounts of useful real-time data, and the introduction of cyber-physical systems.Industry 4.0 is focused on creating solutions that enable digitization and process automation. Therefore, Industry 4.0 solutions have significant capabilities and benefits for application in transport and logistics in order to provide high quality supply chain processes, and improve market competitiveness by eliminating costs

Današnje doba neraskidivih veza fizičkih i digitalnih komponenti zahtijeva velike količine informacija i podataka za generisanje adekvatnih odluka i postizanje efikasnijih sistema upravljanja. Doba Četvrte industrijske revolucije poznate kao Industrija 4.0 prvenstveno ističe digitalnu tehnologiju usmjerenu na integraciju sa Internetom stvari (IoT), pristup velikim količinama korisnih podataka u realnom vremenu i uvođenje sajber-fizičkih sistema. Industrija 4.0 fokusirana je na kreiranje rješenja kojima se omogućava digitalizacija i automatizacija procesa. Zbog toga rješenja Industrije 4.0 imaju značajne mogućnosti i pogodnosti za primjenu u transportu i logistici sa ciljem da obezbijede visokokvalitetne procese lanca opskrbe, te poboljšaju konkurentnost na tržištu eliminacijom troškova.

The problems of traffic safety and the profession of traffic safety are universal problems that require constant strengthening of the system of education and innovation both in syllabuses and in technologies and techniques applied in the field of traffic safety. The purpose of the innovative approach to the education program is to educate undergraduate and graduate students in the field of traffic safety, in accordance with the needs of society, which should provide an interdisciplinary and multidisciplinary approach to safety of all road users, technical solutions and social response to traffic accidents. Traffic safety problems are complex problems, which is why the competencies and skills acquired by engineers should provide knowledge and a deeper understanding of risk while strengthening the applied and practical skills. Innovative study programs must have a common basis for all directions, with a deep knowledge of mathematics, physics and mechanics with an emphasis on a holistic and interdisciplinary approach to the use of engineering in improving traffic safety.

Globally, when accessing and driving in public transport vehicles, women have a problem with fear, experiences of sexual harassment and violence. Women's daily trips are very different from those made by men. These factors make a woman more vulnerable, as standard public transport companies do not consider these characteristics enough. The safe public transport option also helps increase the number of women in economic activities. The way of traveling determines the type of work or shift that the woman will accept. Mobility provides women with financial strength and independence, and currently access to safe public transport, both in Sarajevo Canton and throughout Bosnia and Herzegovina, and it can be said that it is not at a satisfactory level in the region, so urgent actions need to be taken. The concept for the implementation of gender equality within the Erasmus + TRAFSAF project, modeled on EU projects, is that all project partners, both those coming from the segment of higher education and NGOs, keep gender statistics and that measures to promote enrollment must be provided. female populations at all levels of study. It is also a requirement for project participants to increase the participation of women as trainers, as well as to enhance the presence of women in trainings related to traffic safety during the project. These activities should continue after the completion of the project, bearing in mind that it is necessary to integrate gender equality in the segment of traffic safety.
