nothing more apt than that ! 
SINGAPORE — The Land Transport Authority (LTA) said on
Friday (Sept 30) that it is considering whether it is feasible to
activate the Electronic Road Pricing (ERP) gantry located just
before the Kallang-Paya Lebar Expressway (KPE) tunnel entrance,
after the Tampines Road entry slip road.

According to the LTA, the traffic speeds along that
stretch of the KPE between the Tampines Expressway and Airport Road
have “persistently fallen below the optimal speed range of 45kmh to
65kmh for expressways during the morning peak hours on
weekdays”.
This, the LTA said, has led to significant and
persistent traffic congestion.
“We need to monitor the traffic situation in the next
quarter, before making the decision on whether we will turn the
gantry on,” said a spokesperson for the LTA, adding that this
particular gantry has not been activated since the KPE was
open.
“We will have to see if people start using alternative
routes and the situation changes,” the spokesman added.
Meanwhile, the LTA said it has been stepping up
improvements for public transport options to help cater to the
growing population in the north-east area of Singapore, such as the
introduction of two new City Direct bus services from the fourth
quarter of 2016, and recently adding 15 new trains to the North
East Line.
