COMPARISON OF AIR POLLUTION COST ON THE DIFFERENT ROAD CORRIDORS

Abstract

The concentration of activities in the certain areas triggers traffic movements. Different land use generates different amount of traffic, causing different level of traffic delay and air pollutant. Currently, an appropriate policy has not formulated to overcome the concentration of activities related to different road corridors. Therefore, traffic demand management (TDM) should be arranged in order to decrease air pollution regarding to different road corridors. For this reason, this study estimates traffic performance and social costs due to air pollutant emission for different land uses in the city of Malang, East Java, Indonesia. This analysis is based on IHCM (Indonesian Highway Capacity Manual). An approach to estimating pollution costs is based on speed and travel distance in each road corridor. Highway performance for warehousing area has a poor service level. Based on speed analysis, huge concentrations of air pollution such as NO, HC and CO2 have a significant negative impact on the road corridor as a warehousing area. Another analysis based on travel distance also resulted in the highest air pollution cost on road corridor as a warehousing area. To minimize air pollution cost, the local government should have an effort to reduce air pollution cost by implementing TDM strategies such as minimizing road side friction.
