Impact of Traffic Data Distinction between Local and Foreign Vehicles in LTA's Calibration Model for ERP Rates

59 Ms He Ting Ru asked the Acting Minister for Transport (a) whether the traffic volume data used to calibrate ERP rates distinguishes between locally and foreign-registered vehicles; and (b) whether LTA's calibration model accounts separately for the proportion of traffic that has no marginal price sensitivity at individual ERP charging points, such as foreign-registered vehicles on flat-rate fees.

Mr Jeffrey Siow: The traffic volume data does not distinguish between local and foreign-registered vehicles.

Currently, when using Electronic Road Pricing (ERP)-priced roads during ERP operational hours, foreign-registered vehicles with the In-Vehicle Unit (IU) pay ERP charges while foreign cars without an IU pay a $5 daily flat fee. While we do not consider this split in the determination of ERP rates, in 2024, the proportion of foreign-registered vehicles with IUs versus those paying the flat fee is 4:3.
