The basic mission of traffic signalisation is to inform the traffic participants about the characteristics of the road they are moving along, and to give command about the method of moving and other obligations they have to comply with. Their characteristic is the uniformity and recognisability everywhere in the world. In setting traffic signalization the designers have to take into account many factors before the traffic signs becomes the traffic regulator. The traffic sign can hardly bear the load of intersection regulation. For this purpose traffic lights are used. Traffic lights are electronic devices that control and regulate the traffic at intersections thus dictating the throughput and capacity of vehicles on sections of intersections. Designing of traffic signalization at intersections is a very demanding and responsible task which includes the activities of experts of several different profiles, first of all the traffic, construction as well as electrical engineering profile. It is generally known that the traffic light design procedure at intersections consists of several phases, and fuzzification represents one of the starting ones, and the quality of its implementation affects the quality, i.e. efficiency and efficacy of the overall system to be designed.

For the normal flow of goods in one country it is necessary that in every advanced region there is a built modern logistic center with different functions and tasks. The area of Bosnia and Herzegovina is the optimal location for organization of modern logistic and distribution center. In this area it is possible to perform all primary and secondary activities that have the function of handling goods for customers in the immediate environment and the wider gravitational zone.

The application of information and communication technologies (ICT) is becoming an indispensable factor in optimizing transport processes. There is the need for monitoring of shipments during the transport process as an indispensable element of the management and control of transport of postal consignments. For this purpose they use different technologies, and this paper presents the role and capabilities of GPS (Global Positioning System) and RFID (radio-frequency identification) technologies. The work was carried out to show the possibilities for global positioning system (GPS) and radio frequency identification of (RFID) in the organization and rationalization of transport of postal items in Bosnia & Hercegovina.

Everything is already a trend of the arrival of big corporations from the West and purchase of domestic logistic companies. For the corporations to have an overview of their operation and to make timely adequate decisions, they are faced by a very big requirement: how to transfer information from remote locations using the already existing infrastructure. In order to make use of the already existing internet infrastructure, and to safely and efficiently transfer information to the corporation headquarters, the virtual private network (VPN) connections are used.
