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.

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.
