IETT, which carries hundreds of thousands of people to Istanbul traffic every day, advised other major city municipalities, such as Yazkar, which it had installed in 2005 and 2008, that it was satisfied with the air conditioners. As Mr. Kadir Topbas, the mayor of Istanbul's big city, stated in his election declaration, he kept his promise to carry the people of Istanbul on air-conditioned buses in the summer and make them travel coolly. The new 500 buses also allocated funds from the 2007 budget to install air conditioning. In the days ahead, the new air conditioners will be installed in IETT'de air-conditioned bus will not remain, he said.
