Compatibility Issues between ERP 2.0 On-board Units and Some Car Park Gantry Systems

Mr Dennis Tan Lip Fong asked the Acting Minister for Transport (a) whether the Ministry is aware of compatibility issues between ERP 2.0 on-board units and certain carpark gantry systems; (b) if so, how many such incidents have been reported since ERP 2.0 rollout; and (c) what steps are being taken to ensure seamless interoperability between ERP 2.0 and all parking gantry systems islandwide.

All Electronic Road Pricing (ERP) 2 On-Board Units (OBUs) are compatible with the existing Electronic Parking System carparks. However, motorists may sometimes encounter problems accessing such carparks because the OBU antenna in their vehicles are not within range of the carpark antenna. This can be remedied either by repositioning the vehicle, or in other situations, recalibrating the position of the affected antenna. This issue exists for ERP 1 as well.
