Impact of ERP Gantry Removal on Motorist Behaviours and Reducing Congestion

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.

Mr Jeffrey Siow: The Land Transport Authority is conducting a study on user behaviour for the driving experience with Electronic Road Pricing (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.
