New ERP system starts in 2023, no plans for distance charging yet
The way motorists are charged will not change when the satellite Electronic Road Pricing (ERP) system kicks in as the current model has been effective, said Transport Minister Ong Ye Kung.
In a Facebook post yesterday, Mr Ong said it is much better to continue congestion pricing in a way that motorists are used to when Singapore switches to the new ERP system in 2023.
"Distance-based charging is a significant policy change which has many implications and should be studied carefully," he said.
Currently, motorists are subjected to a cordon-based congestion pricing framework where they are charged a one-off fee at gantries leading into more congested areas.
Calls for a distance-based system, where fees would vary depending on how far motorists drive, have drawn mixed reactions.
Some think it is more equitable while others dread its implementation.
The new ERP system is capable of charging by distance, said Mr Ong, "but as a policy we are holding back".
In his post yesterday, Mr Ong addressed questions and grouses from motorists about the new on-board unit (OBU) that will be installed in vehicles for free from the second half of next year.
The OBU comprises an antenna, a touchscreen display and a processing unit. It has drawn criticism for its perceived bulkiness.
Some asked why the three-piece unit could not be integrated into one, as with the OBUs issued to motorcyclists. Others asked if they could use their phones instead and do away with the standard-issue units altogether.
Mr Ong said: "Technically there is no problem having an integrated unit. The issue is heat. From time to time, we park our cars under the hot sun, and a processing unit on the dashboard could not function without a big cooling unit."
Hence the contractor designed it to be a separate module under the dashboard, instead of making it part of a much-larger integrated OBU.
Using smartphones to pay ERP remains a "possible future upgrade", Mr Ong added.
"But to start the new system, better to have a standard issue. If we use our own smartphones for ERP, there will be operational issues like battery running out, forgetting to bring smartphones, et cetera."
On comments about the lack of consultation on the OBU design, Mr Ong said the LTA had some practical constraints, having called an international tender for the project.
It had to choose the best system among the proposals received. Thereafter, it was contractually bound.
"There can be consultations and change of design but it will affect the contract," he said.
"We will have to see how to do this better next time."
