The Faculty of Transport and Traffic Engineering of the University of Belgrade, the Traffic Engineering Module and the Department for Transport Planning and Traffic Control are organizing the 14th International Scientific-Professional Conference on Techniques in Traffic Engineering (Traffic Engineering Saobraćajno inženjerstvo) "TESi". We continue the tradition of gathering traffic experts.Program areas covered by the conference are:- Traffic control and management- Transport planning- Traffic flow and road network efficiency- Traffic design- Parking

ITS systems enable information transparency, manageability and improved response of the traffic system, so they have the epithet of intelligent. The application of ITS solutions on tachographs, as devices that record all the activities of truck and bus drivers, is defined in the ISO 14813-1:2015 Standard in the context of remote data transmission from tachographs. In view of the growing problems regarding violations of regulations on working hours and mandatory vacations for mobile workers, frequent manipulations and misuse of tachographs, as well as regarding the state of traffic safety and increasing environmental pollution, the EU has set stricter conditions in the field of driving these commercial vehicles in its regulations, in the manner of implementing the ITS system of smart tachographs, which brings significant benefits, especially in terms of the work of control authorities as entities that influence better compliance with regulations and the enforcement of legal regulations.

The passenger transport system in cities is the backbone of sustainable urban mobility. The problem faced by the city authorities is the question of choosing the carrier with the best bid in the public call. Services in charge of public transport are often able to choose carriers for one or more lines, and often for the entire area. The basic dilemmas are related to the type of procedure that should be carried out, whether the transport services market is open to competition, what methodology to apply if the transport services market is not declared open to competition, whether the selection procedure should end with the signing of the contract between the city government and the operator, and other questions for which answers are sought.This paper presents an analysis of practices and proposed guidelines for the development and application of the bid operator ranking model in the public selection process.

The paper provides general information and guidelines for the development of Mobility the Hub’s Action Plan of the City of Sarajevo. The action plan will cover a short-medium term time frame and vision, establishing a series of actions and measures to look for a visible and different concept of mobility through five basic components, such as: infrastructure, electromobility, auxiliary services, renewable energy sources and digital solutions. The main purpose of the work is to reduce the negative effects of traffic on citizens and the environment, encourage the transformation of urban mobility and direct the way of thinking towards sustainable development. Above all, defining the criteria for locating mobility hubs in urban areas. The conclusion is that mobility nodes are built in places of high concentration of people, which are places of exchange of passengers and places to which a large number of people gravitate. The Mobility Hub’s concept represents an attractive location/facility that offers users options for environmentally clean and practical modes of travel. It unites infrastructure and services in one place, creating a reliable model for a new way of moving around the city that saves money, is healthier, and increases involvement in green city transportation.

Digitization of mobility services in urban areas made it possible to increase the efficiency of existing public transport services and create a new approach to mobility-as-a-service (shared ride, vehicle sharing, on-demand service, etc.). This gives users new opportunities to access information, plan trips and pay for transportation services. On the other hand, it creates new challenges for users who do not have access to digital technologies or do not have the necessary knowledge and skills to use them. For the development of sustainable urban mobility, it is necessary to ensure the availability of public transport services to all categories of users and provide intuitive interfaces for easier access and use of digitized mobility services. Digitization in the field of mobility must be implemented as part of the broader concept of developing the digital environment of a smart city. Digital technologies support changes in user access to mobility services by encouraging a new approach to mobility-as-a-service that includes service sharing and vehicle sharing with less use of personal vehicles. The overall concept of mobility-as-a-service supports sustainable mobility in the urban area. When implementing the digitization process in the field of mobility, the willingness and limitations of users to accept and use new digital mobility services must be taken into account.

Digitization of transport requires the transformation of the transport system from a physical to a cybernetic physical system. Digitization of transport includes the application of information and communication technologies and artificial intelligence in the transport system. This leads to the transformation of transport processes, but also to a change in the behavior of users and their views on transport and transport services. This creates the conditions for the development of new services and new solutions in the transport system that enable more efficient, economical, safer and more environmentally friendly transport.

In the last 5 years, several projects have been initiated in Sarajevo Canton that are focused on strengthening the identity of the city, promoting and implementing the concept of urban mobility, green and smart city. The issue of energy efficiency is included in all projects and from that aspect, among other things, the improvement of the public city passenger transport service is observed. This paper analyzes the state of public urban transport from the energy aspect, the savings that are achieved, the methodology for calculating savings and the effects that would be achieved through the implementation of planned projects for the development and reorganization of public urban passenger transport.

As smart vehicles begin to roam the streets, new possibilities will emerge for large-scale data acquisition tasks necessary for proactive smart cities applications. Unlike mobile devices, smart vehicles carry powerful sensors and are highly mobile they can cover large areas and perform high quality sensing. The road infrastructure and the information and communication environment of the vehicle need to be adapted to take advantage of the capabilities of smart city functions. This requires a holistic approach to solving the problem of digitalization of transport in a smart city environment.

The development of the smart city concept requires digital transport infrastructure and the deployment of intelligent transportation systems. Successful development of the smart city concept requires ITS architecture. The ITS architecture creates a technical and technological framework for the development and implementation of ITS services that support the smart city's digitized environment.
