Come 1 Nov, 4 more ERPs will be up and another 5 on standby to be activated when traffic get congested. Also operation hours will be extended. Can't be helped. No other better ways. This is the most efficient way as it hurts the pocket. No need to pay super talents to manage with such brilliant solutions. Pay any Ah Beng $5k a month and he will come out with a solution as excellent as this.
