Chee Hong Tat defends ERP2.0 OBU design as “necessary trade-off”

Transport Minister Chee Hong Tat defends ERP 2.0 three-piece OBU designs for cars, citing overheating concern. He rejects WP MP Gerald Giam’s suggestion to utilizing smartphones for ERP purpose due to security and data transmission limitations.



SINGAPORE: During Wednesday’s (8 May) Parliamentary session, Transport Minister Chee Hong Tat defended the new On-Board Unit (OBU) design for the Electronic Road Pricing (ERP 2.0) system, addressing concerns raised by MPs and the public.

Responding to concerns over the bulky three-piece design for cars, Minister Chee clarified the rationale behind it, highlighting temperature concerns as previously explained by the Land Transport Authority (LTA).

PAP MP Lim Wee Kiak asked whether the Ministry of Transport (MOT) could refine the OBU design based on user feedback and explore using smaller motorcycle OBUs for cars.

Minister Chee responded by explaining the “physics” behind temperature variations in car interiors, emphasizing that footwells experience significantly lower temperatures compared to dashboards on sunny days.

He elaborated that while motorcycle OBUs are exposed to ambient temperatures, car footwells can reach up to 38 to 39 degrees Celsius, and dashboards up to 50 to 52 degrees Celsius, posing a risk of overheating for a single-piece OBU.

“With this kind of temperature, if you were to put a single-piece OBU, which means the antenna, the display, and the processing unit all on the dashboard, there is a risk that it could overheat, and then it will affect the functionality of this unit,” he said.

While a cooling fan could potentially be integrated into the OBU’s design, this would inevitably lead to a significant increase in the system’s overall bulkiness, he said.

“I don’t think motorists will want a very big and bulky one-piece unit on their dashboard. It would not be the right design,” he added.

Earlier, the Singaporean community mocked LTA for what they perceived as “poor excuse” for defending the bulky design, highlighting that the previous single-piece IU in ERP 1.0 encountered no heating issues and was considered notably more convenient.

Many have voiced their frustration over the inconvenience caused by the new OBU design for cars.

‘Trade-off’ for flexibility to install processing unit

Addressing concerns regarding the placement of the OBU processing unit, Minister Chee highlighted that during the initial phase of installation, the LTA limited placement to the passenger side.

However, in response to feedback from early adopters, LTA has now extended the option for vehicle owners to install the processing unit on the driver side, contingent upon technical feasibility.

Minister Chee acknowledged that offering more choices could potentially increase complexity and installation time for workshops.

“However, we think the trade-off is necessary, to allow vehicle owners to have the flexibility to customise their preferred options, and not have a “one-size fits all” approach.”

The processing unit securely stores payment cards, such as the NETS FlashPay card, NETS Motoring Card, and EZ-Link Motoring Card, which are used by drivers to pay for electronic road pricing and parking charges.

Additionally, Minister Chee noted that early adopters who initially installed their processing unit on the passenger side have the option to switch it to the driver’s side at no additional cost.

Minister Chee dismisses smartphone integration for ERP purposes, citing limitation

In a supplementary question, Mr Gerald Giam, Workers’ Party MP for Aljunied GRC suggested that utilizing smartphones instead of physical OBUs could streamline installation efforts, reduce hardware costs, and alleviate long-term maintenance expenses.

As ERP 2.0 will provide the option for distance-based charging in future, Mr Giam asked whether the government had considered the significant cost impact that distance-based charging would have on professional drivers such as taxi drivers, private hire drivers, delivery drivers, and riders.

In response, Minister Chee acknowledged the feasibility of using smartphones for accessing ERP information and confirmed that they would be permitted as an option.

However, he stressed that smartphones were not suitable for ERP purposes due to security concerns and data transmission limitations.

“The OBU is designed to transmit the information one way. whereas a phone you would have two-way transmission.”

“Depending on your phone… and the software that you and the apps that you install, I don’t think you can be assured at the same level of data security and systems security, including against tempering.”

Regarding distance-based charging, Minister Chee clarified that while it was under consideration, it was not a definite decision.

He emphasized the importance of a thorough review due to the varying impacts on different stakeholders.

“I urged Mr Giam not to overstate the point. What ERP 2.0 gives us is the option to do this in space if we wish to do so and in the process of doing that certainly we need to consider the impact on different groups of users, and overall what is the benefit to society.”

Mr Louis Chua, WP MP for Sengkang GRC then sought clarification from the Minister regarding whether the new OBU design meets the Automotive Electronics Council’s (AEC) AECQ 100 requirements for reliable operations in Singapore’s climate.

In response, Minister Chee assured that LTA conducted a series of tests to ensure the OBU’s functionality in Singapore’s weather conditions.

These tests considered factors such as temperature and safety aspects, including crash tests to ensure that the OBU would not pose a safety risk to motorists and passengers if installed correctly.

“but what we need to continue to do, is to work with our partners and with stakeholders including motorists, mechanics, service ambassadors to continue to find ways in which we can improve the user experience, and allow more value to be delivered to motorists with these capabilities of the ERP 2.0 system.”

He expressed openness to suggestions for maximizing the value of ERP 2.0 and implementing additional functionalities based on feedback from stakeholders.

Another lie exposed!
Why SingPass app can work flawlessly on any smartphone?

Next election they are also going to see this necessary trade off to opposition. Then can cry father cry mother.

U-turn king chee hong tart still spinning and u-turning in the parliament, to justify his million dollars worth as a minister.
SimplyGo u-turn.
ERP2 u-turn.
Next maybe COE quota u-turn.
Follow by that iguana court case u-turn.
When the people have enough his u-turn, we will tell him to balik kampung.

CB Hong & THE LTA parasites ALL have the same attitude/thinking of “NIH” “Not Invented Here” that is why the parasitic organisation is STULTIFIED/CALCIFIED!!!!!

What a stupid move. The more motorist looks at the screen the more they will curse LTA. A daily painful thorn reminder of LTA s failure and Chees denial .

They should really take a leaf from Taiwan’s ETC system which only has a small tag adhered to the windscreen. Though I must also qualify that for Taiwan’s system to work, gantries have to be present. But this system is much easier to implement, without the hassle for car owners to install a whole set of gadgets in vehicle.

Any low level engineer would understand and would avoid the fatality of a 3-piece machinery design because there are so many points of connections and that means more points of failure, more problem diagnosis all in all.

We voters should trade him off for someone better next GE.
TCSS ministar…hes such an expensive model and useless…making motorists lives difficult…

This PAP is MASSIVELY MASSIVELY DISRESPECTFUL towards Citizens intellect.

To EACH and EVERY citizen, it is THEIR VOTES that matters AT THE END of the DAY and the BEGINNING.

Keep them(him) talking… the more they try to defend the design, the more
they display their idiocy.

Excellent… just keep on talking…!!
Then everyone should know how stupid and brainless $16K a month buys…

What arrogance and condescension! Coming back to the issue of OBU2’s… Read more »

Chee Hong, your performance is rated “F”. A simple erp project you also s rew up big time. Take a pay cut of 100% for one year as a “tradeoff “. Lead by example. Don’t talk cock sing song.

Hope that he doesn’t have to publicly apologise again.It’s futile to convince the public that this is the best device LTA can come out with.A device which is clearly different from what that was advocate years back.So sad to witness such unwelcome things are allowed to be used in our once Sunny Singapore.

Is he implying technology that was 25 years ago, ERP 1.0 is more advanced than today’s technology ERP 2.0?

Decades ago ERP 1.0 is compact and can take direct sunlight directly above dashboard. But after so much advancement in technology, we are moving backwards many steps to ERP 0.2 instead of a 2.0 version

Btw, the govt are the Ones Controlling whatever happen on Sin island plus plus. Then when things go wrong blame on others or scapegoats or malicious actors … Then wanna say otherwise?!?

Stubbornness. Arrogance. Not able to convince. These are defences – goodness. Use your dick to defend against impotence, this is better defence PAP folks.

Necessary trade off?
Money all paid already, pervious minister never do his job, CANNOT U TURN LIAO!
This shit piece of equipment would be massive headaches a few yrs down the road!
Chee would have taken his millions and say….GOOD BYE!😆😆😆

Maybe, just maybe, … it ain’t quite working out this time, on this particular ERP2~OBU/POC (piece of crap) !!!

Its worked like a treat in the past, when all this regime had to do was, … reassure, repeat and remind the nation, of any ‘ol shit and it’ll stick, … even if it was a bare~faced lie like FT creating opportunities for the locals or public housing remains accessible and affordable to all !!!

Talk and talk and talk BLOODY WASTE OF TIME, RESOURCES AND Jumping On People’s NERVES.


Show. Present statistics. Proofs of experiments, if tests conducted what is what. This then is CONVINCING. Saliva POURING DOES NOTHING, wake Up Millionaire BASTARDS.
