The Government of Singapore has delayed the deployment of the Global Navigation Satellite System (GNSS) electronic road pricing (ERP) system, to the second half of 2023 due to the global chip shortage. After the system is deployed, implementation works- will be undertaken for a period of 18 months. The satellite-based network was originally slated to be implemented during 2020, but was delayed to early 2021.  The impact of COVID-19 on global supply chains is the main reason for the revised timeline.

The work will include the installation of a new on-board unit to replace existing in-vehicle units, which are required for all registered vehicles in Singapore. The on-board unit is regarded as essential to the new ERP system, providing drivers with services such as electric charging location alerts and real-time traffic information. A global microchip shortfall, however, is having an impact on the availability of necessary parts required for these devices. Due to supply chain uncertainty, the on-board units should only be implemented once production is reliable and sufficient.

The Land Transport Authority (LTA) will collaborate with NCS Group and Mitsubishi Heavy Industries (MHI) Engine System Asia for the development and installation of the on-board units.

Singapore’s current ERP system, which was implemented in 1998, collects toll charges as vehicles, including motorcycles, pass through gantries using a combination of smart card and radio frequency identification (RFID) technology. However, the current technology is becoming increasingly expensive to maintain, and the new GNSS infrastructure will eliminate the requirement for large gantries in favour of slimmer alternatives.
