摘要
The urban economic development needs transportation facilities. People move form one location to the other rapidly. The amount of vehicle increases, it also increases lead content in the air. The human health cost increases as lead content in the air increases. The reduction of lead content for 10 percent, it gives economic value as much as Rp. 11.828.365.993,- （US$ 985,697.17）. And if lead content decreases for 25 percent, it yields economic benefit as much as Rp. 34.509.073.173, - （US$ 2,875,765.10）. The analysis of benefit uses exposure-response function method. Analysis of people awareness for keeping the environment uses contingent valuation method survey and willingness to pay. People awareness to keep their environment and to decrease lead content is not good enough, despite the fact that there is some increase of awareness, for example the awareness of using alternative path- through ring road on peak hours.
