The Sustainable Urban Mobility Plan of the Braşov Growth Pole (PMUD) and the Integrated Urban Development Strategy Brasov (sidu) highlighted between the main problems affecting the quality of life and mobility in Brasov municipality and its functional area the air and noise pollution due in particular to the heavy road traffic in the municipality. This is because the public transport system is not attractive, so a significant proportion of residents, commuters and tourists prefer to use private cars, leading to the negative consequences mentioned. Thus, the aim of the project is to increase the quality of life of the inhabitants of Brasov by improving the environmental conditions as a result of achieving a sustainable transfer of part of the modal share of private transport by cars to public transport. The general objective of the project is to reduce carbon emissions in Brasov by increasing the attractiveness of public transport as a result of the modernisation of the infrastructure necessary to secure and maintain the fleet of vehicles in optimal conditions. The attractiveness of the public transport system depends primarily on the conditions it offers: comfort, predictability, speed, safety. Ensuring predictability depends to a large extent on the operator’s ability to ensure timely maintenance of vehicles, while minimising the periods during which they are not operational due to technical reasons, as well as the cleaning and comfort conditions that passengers expect. Thus, increasing the attractiveness of the public transport system is intended to discourage the use of the car for urban journeys and to reduce congestion and chemical and noise pollution caused by private transport, leading directly to lower CO2 emissions and other emissions (NOx, PM10, etc.). According to the “no project” scenario defined in the SUMP, the increase in the number of private cars in the near future will lead to a sharp increase in carbon emissions, which is why the “with-project” scenario (“do something”) requires concrete measures to increase the number of people using public transport and to move away from the use of private cars alike. The realisation of the investment is likely to increase not only the efficiency of the public transport activity, but also the degree of attractiveness of this mode of transport among the population of the municipality and those in the metropolitan area working within the municipality. In addition, the project is part of a complex, integrated and complementary approach, along with other SUMP projects selected on the priority project list of DJ FESI Brasov (projects aiming at the acquisition of public transport means, infrastructure used by public transport, components of traffic management systems as well as other investments aimed at re
