Electronic Road Pricing (ERP) is an electronic system of road pricing. It uses a dedicated short-range radio communication system to deduct ERP charges from smart-cards inserted in the in-vehicle units of vehicles each time they pass a pricing point when the system is in operation. The pay-when-you-use principle helps make motorist more aware of the true cost of driving. This way, road usage can be optimised.

Rates Review

The Land Transport Authority (LTA) has completed its quarterly review of traffic conditions on roads and expressways. 


Evening ERP on Eastbound PIE

Traffic conditions along the eastbound PIE during the evening peak hours have deteriorated in recent years. In particular, eastbound PIE near Adam Road and Mount Pleasant have experienced heavy congestion, with traffic speeds significantly below the optimal range of 45km/h-65km/h, going in fact below 40km/h.

To manage this congestion, LTA will activate the ERP gantry situated along PIE (Changi) after Adam Road and the gantry at the Mount Pleasant slip road into PIE (Changi), during evening peak hours.

The gantries will start operation from 20 February 2017.


Managing Congestion on KPE (ECP)

As announced in September 2016, LTA has been reviewing the need for ERP to manage traffic congestion along the stretch of the south-bound Kallang-Paya Lebar Expressway (KPE) between Tampines Expressway and Airport Road during the morning peak hours on weekdays. The latest quarterly review shows that traffic speeds along this stretch have consistently remained below the optimal speed range of 45km/h to 65km/h, dipping to as low as 30 km/h.  

To manage this congestion, works have already commenced to prepare for the activation of the ERP gantry situated at the Tampines slip road into KPE (ECP), just before the KPE tunnel entrance. LTA will continue to monitor the traffic speeds along KPE in the next quarter, before finalising the ERP operating hours and rates.


Next ERP Rate Review

The second quarterly ERP rate review for 2017 will take place in May. Please refer to the news release for more details.
