The action that has placed Arak among the country's leading cities in using a clean transportation fleet. Given Arak's special environmental conditions and air pollution, the city administration, with a responsible and program-oriented approach, has chosen the development of clean transportation as one of its main priorities. Electric buses, due to the absence of pollutant and noise emissions, play an effective role in improving air quality and creating calm in urban traffic. In addition to their environmental benefits, this new fleet has also brought a remarkable transformation in terms of comfort, and with features such as suitable heating and cooling systems, comfortable seats, easy access for people with disabilities, and completely silent operation, it has provided citizens with a safe and pleasant experience of intra-city travel, reducing travel time and increasing public satisfaction. Continuing along this path, the municipality of the metropolis of Arak, by consolidating its development-oriented outlook, has concluded a contract to purchase 20 more electric buses at the same previous price, of which, according to the planned schedule, 12 units will soon be added to the city's public transportation fleet; an action that demonstrates the continuity and seriousness of the city administration in renewing the fleet. This purposeful move indicates that the Arak municipality considers fleet renewal not a temporary measure, but a long-term investment in the health of citizens and a greener future, and with this approach, it has introduced Arak as a successful model on the path to clean transportation and a sustainable city.
