ERP

Written Reply to Parliamentary Question
Ms He Ting Ru asked the Acting Minister for Transport
a. notwithstanding roadside signages and on-board unit alerts, whether any research has assessed how removing physical ERP gantries may reduce motorists' responsiveness to charges and willingness to divert from priced roads;
b. whether this may necessitate higher rates for equivalent congestion-reduction outcomes; and
c. whether comparative data between both systems will be published.
Reply by Acting Minister for Transport Jeffrey Siow:
1. The Land Transport Authority (LTA) is conducting a study on user behaviour for the driving experience with ERP 2.0. The study would examine the effectiveness of new visual cues and alerts in place of the physical gantry. Outcomes of the study will inform the design and implementation of ERP 2.0's road guidance features, including road signs, road markings, and digital notifications. More details will be provided in due course.
