LTA to trial new road signs and markings under ERP 2.0

In earlier reports, LTA stated that from 1 January 2027, all Singapore-registered motor vehicles must have its ERP 2.0 OBU installed to travel on public roads.

This new system leverages Global Navigation Satellite System technology, eliminating the need for physical ERP gantries on Singapore's roads. As such, LTA will be trialling the use of new road signs and markings as visual cues for ERP charging locations.

These new signs and markings will complement OBU alerts, which will notify motorists in advance of ERP charge locations, provide information on prevailing ERP charges and indicate the amount charged within the location.

And to test its effectiveness, LTA will be conducting a user experience study in two phases. The first phase, which was held in March 2026 at Bayshore Drive, tested road markings such as the oval blue "E" symbol and a 25-metre stretch of road painted in blue.

During Phase 1 of the study, skid resistance tests were conducted on the road markings to ensure that the surfaces of the road markings met standards required for safe road surfaces. LTA also tested the visibility of the road signs and markings.

As for the second phase, by taking into account feedback from the first, five different combinations of road signs and markings will be tested across five expressways and arterial roads from 1 June to 31 July 2026.

The selected locations are existing ERP charging locations and represent a range of traffic and road conditions. The findings from the study will guide the development of clear and intuitive visual cues to support a smooth transition to the gantry-less ERP 2 system when it is implemented from 1 January 2027.

As such, the LTA is partnering with the Automobile Association of Singapore, Singapore Road Safety Council, as well as other stakeholders from the motoring community with the aim of inviting 1,000 motorists to participate in the study.

Said participants will get to experience the full suite of upcoming OBU functionalities, including more ERP-related notifications, automatic payment of checkpoint tolls, and using the OBU's touchscreen display for roadside parking payments.
