Revisions to Design and Technology for On-Board Units for Next-Generation Electronic Road Pricing System and Measures to Ensure Compatibility with Latest Technology and Consumer Preferences
Ministry of TransportSpeakers
Summary
This question concerns MP Yip Hon Weng’s inquiry regarding revisions to the Next-Generation Electronic Road Pricing On-Board Units (OBU) and measures to maintain compatibility with technological trends. Minister for Transport S Iswaran stated that the OBU is designed for security and interoperability with existing systems and global navigation satellite technology. Although no fundamental redesign is planned, motorist feedback is being used to refine installation positions and the user interface. The Ministry is also exploring allowing smartphones to function as display screens and utilizing modular designs based on open standards for future-proofing. Minister for Transport S Iswaran noted that the system will continue to be monitored to incorporate technical refinements as they become feasible.

11 Mr Yip Hon Weng asked the Minister for Transport (a) what are the revisions to the design and technology for the On-Board Units for the Next-Generation Electronic Road Pricing System since the last update; and (b) how will the Ministry ensure that the Unit stays compatible with the latest technology and consumer preferences when it is implemented in mid-2023.
Mr S Iswaran: The On-Board Unit (OBU) has been designed to balance several needs. These include performing the charging functions accurately and securely in different vehicle types and environments, as well as being able to interoperate with both the existing system and the new global navigation satellite system (GNSS).
The Land Transport Authority (LTA) conducted surveys and focus group discussions with motorists last year to better understand and meet motorists’ preferences for OBU installation positions and display user interface. While this will not lead to a fundamental redesign of the OBU at this juncture, it will help improve the motorists’ experience.
As previously announced, we are also studying the option of allowing motorists to use their smartphones as the display screen of the OBU and will be engaging the industry on possible ways to implement this.
The nexgen ERP system is designed for long-term use. It is supported by GNSS technology which remains one of the most commonly used navigation technologies today. In addition, the nexgen ERP system is based on open standards and adopts a modular design to provide greater flexibility for future updates and improvements. We will continue to monitor technological developments and incorporate refinements where feasible.
