From Channel NewsAsia on LTA's recent comments:
"Besides trying to come up with a more holistic way of dealing with congestion, LTA will also see if optimal speed ranges, which currently should not fall below 45 kph for expressways and 20 kph for other roads, need to be changed.
LTA is also installing ERP gantries at Toa Payoh Lorong 6, Upper Boon Keng Road, Kallang Bahru Road and Geylang Bahru Road, but will only start charging if traffic conditions worsen."

Yah right. So by changing their definition of congestion and lowering their "optimal speed ranges", they will have less congestion. Brilliant.
And sure, we install these gantries, and will only start to charge when traffic congestion gets worse. What a joke.
