SINGAPORE – Possible road signs and markings for the new Electronic Road Pricing (ERP) system will be tested at five more locations in June and July.
The signs are meant to serve as visual cues of ERP toll charging locations when physical gantries are removed under the new system, which will be implemented on Jan 1, 2027.
The latest trial expands on an earlier one conducted in Bayshore Drive in March, said LTA in a release on May 12.
Designs of the ERP road signs and markings have been refined following feedback from the Bayshore trial, added LTA.
Five different combinations will be tested across five expressways and roads from June 1 to July 31.
The selected locations are existing ERP toll charging locations which represent a range of traffic and road conditions. “This will enable comprehensive testing across different scenarios,” LTA said.
The five locations for the latest trial are:
PIE – Westbound, after Kallang Bahru on Woodsville Flyover
PIE – Westbound, before Eunos Link
CTE – Southbound, from Serangoon Road 2
Marina Boulevard to MCE, eastbound
City-bound AYE after Jurong Town Hall
It will involve about 1,000 motorists.
In the Bayshore Drive trial, road markings such as the oval blue “E” symbol and a 25m stretch of road painted in blue were tested.
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, said LTA. Visibility of the road signs and markings was also tested.
The new ERP 2 system leverages satellite technology, rather than gantries, to determine a vehicle’s location for toll charging. This is facilitated by the use of an on-board unit (OBU) in the vehicle.
The new signs and markings will complement alerts on a vehicle’s OBU, which will notify motorists in advance of ERP charge locations, provide information on prevailing ERP charges and indicate the amount charged within the location, added LTA.
LTA said it is partnering the Automobile Association of Singapore, Singapore Road Safety Council and other stakeholders from the motoring community to invite motorists to participate in the study.
Participants will also experience the full suite of upcoming OBU functions, including more ERP-related notifications, automatic payment of checkpoint tolls and the use of the OBU’s touchscreen display for roadside parking payments, said LTA.
LTA said on May 12 that around 960,000 vehicles have been fitted with the OBU, making up more than 96 per cent of Singapore-registered vehicles.
Motorists who are not participating in the trial can still provide their feedback on the road markings and signs to LTA by sending their feedback to [email protected] by July 31.
