During the first phase of the study, LTA tested ERP road markings and signs along Bayshore Drive. The markings included blue oval “E” symbols and a 25m stretch of road painted in blue.\u00a0<\/p>\n
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, while the signs and markings were also tested for visibility.<\/p>\n
“LTA has refined the designs of the ERP road signs and markings for the second phase of the study, taking into account feedback from the first phase,\u201d it said.<\/p>\n
LTA added that it will test five different combinations of ERP road signs and markings across four expressways and an arterial road from Jun 1 to Jul 31.<\/p>\n
The westbound PIE section after Kallang Bahru on Woodsville Flyover will have a blue oval ERP symbol painted on each of its five lanes to indicate the start of the ERP charging location.<\/p>\n
The westbound PIE section before Eunos Link will also feature the oval blue ERP symbols on its four lanes.<\/p>\n
The southbound CTE section from Serangoon Road will have a 25m stretch of its two lanes painted blue.<\/p>\n
A section of Marina Boulevard towards the eastbound MCE will also have a blue 25m stretch on its two lanes, but with the addition of the words \u201cERP\u201d in white painted in the centre of each lane.<\/p>\n
The section of the citybound AYE after Jurong Town Hall Road will have 25m blue lines painted on its sides, as well as “ERP painted in white at the centre of each of its four lanes. The lane dividers between the blue lines will also be blue rather than white.<\/p>\n
LTA said the selected locations are existing ERP charging locations which represent a range of traffic and road conditions.<\/p>\n
“This will enable comprehensive testing across different scenarios,” said LTA.<\/p>\n
“The findings from the study will guide the development of clear and intuitive visual cues to support a smooth transition to the gantry-less ERP2 system when it is implemented from Jan 1, 2027.”<\/p>\n
Motorists who are not participating in the OBU aspect of the study can still provide feedback on the trial road signs and markings to LTA by Jul 31, the authority said.<\/p>\n
As all ERP charging will be done via GNSS from Jan 1, 2027, the finalised new signs and markings from the study will serve as cues for motorists on charging points.<\/p>\n<\/div>\n
