The new on-board unit (OBU) to replace the current in-vehicle unit (IU) in existing Singapore-registered vehicles will be installed free of charge starting from the second half of 2021.
In a media release on Tuesday (8 September), the Land Transport Authority (LTA) said that the installation exercise will take about 18 months, as it begins to replace the existing Electronic Road Pricing (ERP) system with one that leverages on the Global Navigation Satellite System.
It expects to make the switch to the new system in mid-2023.
The new system will do away with the bulky gantries, while the OBU can incorporate other services such as real-time road traffic updates, as well as locations of nearby School Zones and Silver Zones to alert motorists to look out for more vulnerable road users.
It will be mandatory for Singapore-registered motor vehicles to have the new OBU, which will have two designs:
Motorcycles: A single-piece design tailored for mounting on a motorcycle.
All other vehicles: A three-piece design, comprising an antenna and a touchscreen display tailored for mounting to the windscreen, and a separate processing unit that can be mounted beneath the dashboard.
