The key change that was supposed to be done by the Federal Government (Pers Kewajipan is a JKR road) at the Persiaran Kewajipan & KESAS interchange was to build u-turns to KESAS to convert to current 4 phase traffic lights into 2 phase, and even with the option to do away with the traffic lights during peak hours. 

The other thing that we have pushed for is to bar heavy vehicles from Persiaran Kewajipan during peak hours, to lessen the load. 

While both the approvals and implementation falls under the Ministry of Works, we are following up and pressing for these measures for the benefit of Subang Residents.
