air pollution

Bandarlampung is getting more and more crowded, traffic jams always happens here and there. This condition is worsen as there are some street that cross the railway. They are in Kampung Baru, Labuhan Ratu, Jl. Sultan Agung, Way Halim, Jl. Urip Sumoharjo, Kedaton, Jl. Hanoman Kampung Sawah, Jl. Pemuda Tanjungkarang, Jl. Tulang Bawang, Kebon Jeruk, Jl. Gajah Mada and Jl. Perintis kemerdekaan.

When the train passes those street. Hundreds of cars and motorcycle have to wait for the train to get through. I notice not many of the drivers/riders turn off their vehicle's engines while waiting for the train to pass though they are idle for more than 3 minutes. How much gas is wasted? The vehicles do not move, but the gas is burnt. Do they realize that they had waste the gas and had made the earth suffer from air pollution at the time.
