The urban economic development needs transportation facilities. People moves form one location to the other rapidly. The amount of vehicle increases, it also increases lead content in the air. As a research topic is the human health cost increases as lead content in the air increases. Lead impacts increase public health cost. This research identifies the determinant of public health cost and estimates the respondent’s willingness to pay (WTP). The respondents are 146 people in three areas of study, Yogyakarta City, Sleman Regency, and Bantul Regency. Dose response method determinates the valuation of lead impact caused by emission to human health. Contingent valuation method estimates the respondents’ WTP to take care human health by keeping the environmental condition. It is analyzed by ordered probit model. By increasing lead pollutant, the health impacts are 123,647 cases of incremental child IQ, 15,783 cases of hypertension, 17 cases of coroner core, and 127 cases of premature mortality. Total health compensation cost because of lead impact is 1,469,594,723,409 (US $ 122,466,226.95). The increasing of the probability of respondent’s WTP is only 0.233 percent, if the dependent variables increase one percent. It indicates that people’s 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.
