The benefits of using ETC instead of manual toll payment are clear. It has been observed in Philippine expressways that the average service time per vehicle with E-pass is 1.5 seconds compared to 15 seconds for manual collection. This translates to reduced traffic congestion at toll plazas, lower fuel consumption, less air pollution, and therefore less economic losses. However, the current number of E-pass subscribers is still small compared to the number of toll road users. Possible reasons are the high initial cost of subscription, infrequent use of tollways by some users, lack of information, etc. To ascertain these reasons and to understand the factors that can increase E-pass subscription, it is important to know the perception of people about the ETC. This study aims to gather people's assessment of ETC; identify factors that would make non-ETC users shift to ETC; relate socio-economic - characteristics with ETC acceptability; and develop a framework estimating the environmental benefits of ETC.
