The Impact on Mobile Phone use on Pedestrian Road Crossing Behaviour

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.

Establishment of a System for the Transport of Goods by Unmanned Aircraft

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”.

As a the most important factors for achieving the organization’s ability to achieve sustainable success and business continuity the following factors are highlighted: understanding the context of the organization, the organization’s resilience to environmental influences, application of approaches “Risk-based thinking” and “Risk-based management”, integration of management systems, continuous improvement and application of international standards for management systems. The application of the described approach is possible, except in transport, in other organizations, taking into account its specifics.

Telematics of new vehicles for the purpose of pedestrian safety

Pedestrians are a vulnerable group of traffic users who most often suffer serious physical injuries in collisions with motor vehicles, which very often have a fatal outcome. The modern automotive industry is investing great efforts in the development of active and passive protection systems for all traffic participants, including pedestrians. Pedestrian protection is tried to be achieved by changing the shape of the front parts of the vehicle, by using plastic materials with higher deformation potential which, in collision with the body of the pedestrian, will spend most of the impact energy on its own deformation and thus maximally spare the delicate biological tissue of the pedestrian. Instead of protruding, rigid metal structures of insignificant elasticity and deformation potential, today’s cars are characterized by appropriate body design, use of high elasticity materials and deformation of contact surfaces, specially shaped and integrated bumpers, elastic and raised bonnet, headlights integrated into the contour of the vehicle front which are capable of absorbing part of the impact energy. Modern research shows a certain efficiency of these improvements on modern cars. Most of these studies are of the experimental type and are done in strictly controlled conditions on dolls, often commissioned and funded by wealthy automobile corporations, while there is less research in real field conditions. Recently, experiments have been made with testing the active bonnet, the airbag under the bonnet, and the google model of gluing the pedestrian body.

Selection of the Optimal Toll Collection System for the Purposes of Sustainable Development of Transport in the Republic of Srpska

Transport system has multiple interactions and multidimensional effects on the environment, by way of, amongst other, land acquisition and urban pollution; on economic development with regard to the GDP growth; as well as on social equity in terms of access, quality of life and health of population. This paper considers the possibility of introducing toll collection in the Republic of Srpska. The goal of the developed model is to increase revenue, which could be directed to the sustainable development of transport in the Republic of Srpska. The selection of a toll collection system has been made taking account of: economic, traffic, technical, organizational and exploitation criteria. Multiple-criteria approach has been applied together with the Analytic Hierarchy Process.

Analysis of the Impact of no Passing Zones on Fuel Costs

The primary task of traffic and transportation planning is to improve the conditions of traffic and level of service on the entire road network. On three sections, which were analyzed in this paper, the possibility of reducing the precentage of no passing zones was noticed, by changing the horizontal signalization on the segments of road section where the clear visibility for overtaking was determined for one direction of the two-way highway. In the first part of the paper, the analysis of traffic conditions on the existing and on the newly designed variants of all three observed road sections was performed. Analysis of the level of service on the intersections that are part of this research are done in chapter 2. Increasing the speed on the newly designed section results in a reduced travel time and this leads to savings in fuel costs as shown in chapter 3. Traffic forecast for the planning 2029 is done in chapter 4, the forecasted traffic load implies future traffic volumes for which adequate capacities of the road network need to be provided. Chapter 5 is based on determination of the relationship between the benefits brought by the newly designed variant and the costs that are realized during its construction. The results of this analysis were used as input data for the economic evaluation of the project solutions, where the savings in fuel costs were analyzed.

Models of Management of Railway Infrastructure of Montenegro

In time of rapid economic and technological change and turmoil, no one can manage business successfully, just because they think they are ‘smart’. In order to successfully manage organizations in the era of dramatic change, in this case ŽICG (Railway infrastructure of Montenegro), it is no longer sufficient to master the classical management process, but also to master the overall quality of management process. In order to achieve the best possible business results in the Railway Infrastructure of Montenegro, the theoretical and practical knowledge on which the management process is based, starting from planning (goal setting, determining ways to achieve goals, allocating required resources), organizing (a division of labor, delegation of authority, coordination), leadership (supervision, motivation, remuneration and punishment, training), conflict resolution) and lastely control (choice of control parameters, monitoring of results, comparison of planned and realized, taking corrective actions). In order to improve the current situation, the models of management of railway infrastructure are considered, for which as a manager builds and invests in railway infrastructure, takes care of its modernization, current maintenance, provides access and allocates infrastructure capacities and organizes and regulates railway traffic. In the processing of the management model, the work relies on the Strategy for the Development of Transport of Montenegro in the period 2019-2035, which establishes the situation in the areas of transport, defines the infrastructure, organizational and operational goals of the development of the transport system, which are realized through time and long-term implementation plans.

Traffic Demand Management Tools in Small and Medium-Sized Cities

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.

Advanced Airspace Management Process

In order to increase efficiency and reduce delays, an improved airspace management process must be implemented leading to optimal route planning, better utilization of available airspace and increased performance targets in service delivery - through the establishment functional blocks of airspace (FABs). The Single European Sky (SES) project supports the establishment of the FAB through greater optimization and better performance, strengthening the ATM network through the introduction of the main objectives of the regulatory package, redesigning the European airspace in order to establish new air traffic flows; creating an increase in additional capacity, all with the aim of increasing the efficiency of the ATM system.

Training of Drivers for Safe Transport of Dangerous Goods

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.
