To implement equity and consistency in toll fees, to respond to the expectation of freeway users and to avoid the collapse of toll collection system, Taiwan Area National Freeway Bureau, MOTC began to design the transition from flat-rate toll collection to distance-based toll collection. Moreover, TANFB planned to implement of electronic toll collection (ETC) in replacement of the manual flat-rate toll collection in order to reduce the manpower and use of land for toll stations and, thereby improve the toll collection efficiency of freeway through electronic toll collection. In consideration of improving administrative efficiency, TANFB launched Electronic Toll Collection (ETC) by BOT in 2003, when the government proposed “Private Participation in the Deployment and Operation of Freeway Electronic toll collecting system” and designated private-sector companies to establish and operate electronic toll collection (ETC) system. Through such approach, the creativity and efficiency of private-sector companies can be introduced to expedite the overall project promotion.
