The general objective of the project is to improve public transport in the municipalities of Ploiești and Târgu Jiu by purchasing trolleybus rolling stock on selected public transport routes, through an integrated approach based on the Sustainable Urban Mobility Plan for the Ploiesti growth pole, respectively the Sustainable Urban Mobility Plan (PMUD) of Targu Jiu municipality. This objective involves reducing carbon emissions and increasing the attractiveness of public transport by providing better conditions (modern, low floor, 100 % electric zero-emission vehicles, faster, less noisy, with ITS facilities – intelligent technical systems), i.e. by offering transport alternatives, discouraging travel by car and increasing the number of people who will use public transport.
