Mobile phone use at pedestrian crossings has been recognized as a growing problem in the field of traffic safety. The objective of the paper is to analyze the impact of mobile phone use at pedestrian crossings considering specific territory. Signalized and unsignalized intersections are observed in the study. Several factors having the impact on unsafe pedestrian crossing behaviour are identified such as: age, location and the type of mobile phone using. The model of unsafe pedestrian behaviour based on displayed mobile phone use while crossing the intersection is constructed. It has been shown in this research that talking and texting on mobile phone distract pedestrians. Listening to music does not affect pedestrians to behave unsafely because it requires less cognitive activity than talking or texting. Also, location affects the pedestrian crossing behavior. The results of this research can serve the purpose of preventing the mobile phones use and reduce the negative impact on pedestrian crossing behavior.

Delivery of goods by air using unmanned aerial vehicles is one of the many potential applications of unmanned aerial vehicles. The problem in the operationalization of this type of use of unmanned aircraft is, on the one hand, the limitation in the legal regulations and, on the other hand, the lack of a unified system of control, management and servicing of unmanned aircraft. The paper describes a model of a unique, integrated system of control, management and servicing of unmanned aircraft that can be logistically supported by an extensive network of small airports in the Republic of Serbia. The economic profitability of this way of delivering goods is correlated with the real needs of the market with the efficiency and effectiveness of delivery on the principle of “today for today”.

The safety of transporting dangerous goods is conditioned by a number of factors, many of which are significantly influenced by drivers. Drivers, as the central component of human resources, are expected to react appropriately at all times during the performance of their professional activity, in order to prevent the occurrence of a traffic accident or reduce its consequences, thus contributing to the safe transport of dangerous goods. He is expected to assess the situation and make a valid decision in accordance with the set tasks. Due to irregularities and omissions in the work when making an independent decision on how to act in certain moments, the driver directly influenced the occurrence of a large number of accidents. In order to minimize the driver’s failures in the transport process, appropriate attention must be paid to their training.

The function of the public urban and suburban passenger transport (PUPT) system as a transport activity is to provide transportation services in a certain urban area. By using new solutions in traffic demand management in small and medium-sized cities, which do not have an efficient PUPT system, in combination with paratransit systems, we can significantly increase the combined mobility of the population, reduce the use of passenger cars, reduce the need to build new roads, and take full advantage of the PUPT system. This paper presents the traffic demand management tools by which these effects can be achieved.

The use of aluminum in modern cars began in the early 1970s, when under the pressure of the oil crisis, car manufacturers around the world began to reduce the weight of cars in order to achieve the lowest possible fuel consumption. The first applications of larger volumes were radiators, engine blocks and wheels. Meanwhile, in Europe, the average amount of consumed aluminum has continued to increase, reaching an average of 180 kg per car. Aluminum castings, forgings, sheets and extruded parts are used for a large number of car parts, including car bodies, chassis, suspensions, wheels and many others. The use of aluminum is also important for hybrid and battery electric cars. Due to the threat of global warming due to the greenhouse effect, it is very important to reduce the weight of the car by using aluminum, and thus fuel consumption.This paper explains why, now more than ever, vehicle weight reduction is necessary and how aluminum can be used to further improve the sustainability and safety of future generations of cars. Special attention is given to the use of aluminum for car wheels, which represent almost 15% of the average aluminum content in passenger cars.

In the process of compensation for the damage suffered by the aggrieved party as a result of a traffic accident, it is often necessary to provide expertise to determine the cause of the accident, the aggrieved party’s contribution to the accident, or increase in the amount of damage. Formally and legally, it is necessary to observe the institute rule of shared responsibility. Shared responsibility is an institute rule that marks the contribution of the aggrieved party to cause damage or to be greater than it would otherwise be. Within the framework of this paper, the model of traffic accident expertise in civil procedure is investigated, primarily from the aspect of the contribution of the inadmissible action of the aggrieved party in the occurrence of the accident or increase of the damage.

The paper deals with the issue of lifecycle stages of motor vehicles. This topic is trending around sustainability issues, given the very unfavorable age structure, increasing import of used cars, which causes an increasing intensity of the number of waste vehicles. This situation creates problems with management of all kinds of waste. Optimal life of a motor vehicle is 10-15 years on average. Individual phases of lifecycle are indicated differently with multiple parameters. All phases are influenced by many factors, but this paper focuses on maturity and decline phases. Key findings suggest that different market, business and environment indicators define the key stages of the lifecycle-maturity and decline stages. Future research will expand the sample on other countries from the Balkans region.

A significant percentage of entrepreneurs, micro and small companies in Serbia do not have adequate outbound logistics capacities in order to register significant growth in business. The needs of everyday business and the demand for certain products and services is a reflection of the quality of products, and very often it is not realized in full potential, due to poorly dimensioned aspects of logistics function, or due to insufficient operational capacity of the company itself. The key problems of small companies from Serbia, which are trying to internationalize their products or services, lies in the fact that Serbia (as a country) generally has very poor outbound logistics and transport efficient solutions and capacities. In addition, transport costs and supply chain length have critical impact on the ability of a small company to meet demand outside the local market. The complexity of the problem is affected equally by internal capacities of micro and small companies, but also by weak external support for specialized outbound logistics services (transport, transshipment, etc.). These problems will be analyzed on a sample of small Serbian companies that deal with different fruit cultures processing, and are trying to conquer new markets. The result of the conducted research serves in an attempt of narrowing the problem to specific sectors of the industry, which are affected by inadequate logistics capacities. Future research could contain concrete measures to improve the delivery process and internationalization of goods for companies outside large systems (corporations), by defining concrete proposals to improve outbound logistics management capacities in Serbia.

The bus subsystem is the holder of the public transport function in many cities with a dominant representation of diesel-powered buses. In the last few years, electric buses (E-bus) have been increasingly used in many cities around the world (China, Europe, South America), making them the main alternative to conventional buses (diesel, CNG). The main advantages of using electric buses compared to conventional buses are higher energy efficiency, zero pollution emitted at the local level, more favorable carbon dioxide emissions observed at the regional or national level depending on the method of obtaining electricity, lower noise level. Since 2016, five electric buses have been operating in Belgrade on the EKO 1 line (Vukov spmenik-Belvil). The paper will present the environmental benefits of the use of electric buses observed through TTW (Tank to Wheel) and WTW (Well to Wheel) analysis, compared to diesel and CNG buses.

The reconstruction of the passenger car body is approached for several reasons: development of a new model, installation of a new unit, compliance with new regulations, weight reduction, introduction of new materials and technologies, etc. It can be realized through: constructive changes, introduction of new materials or combined. The paper analyses the effects of implemented changes in order to meet regulations as well as the need to change existing technologies on the example of a car body. The introduction of new materials can significantly improve the existing structure with minimal changes.
