Make “complete stops” at Persiaran Kewajipan T-junctions

There are five main junctions along the USJ stretch of Persiaran Kewajipan which at most times are pretty busy. However, only two of these which are cross junctions have complete stop for all lanes when the traffic lights turn red. These are at the Persiaran Kewajipan- Persiaran Subang Permai junction (near Da Men Mall) and Persiaran Kewajipan-Jalan Damai / Jalan USJ 18/8 junctions.

For some reasons that this author could not comprehend, three major T-junctions along the USJ side of Persiaran Kewajipan  do not have complete stops for all lanes on Persiaran Kewajipan when the traffic lights on either direction on this major road turn red.

No total stop at the Persiaran Kewajipan-Persiaran Perpaduan junction (near Taipan LRT station)

Traffic on Persiaran Kewajipan travelling towards USJ 21 direction (blue arrow) need not stop at the Persiaran Perpaduan junction. This makes it very dangerous and difficult for Persiaran Perpaduan traffic (red arrow) turning right at this junction as they have to filter into the main flow on Persiaran Kewajipan, often making it very dangerous for the road users who want to turn into USJ Police station or even further down to filter to the left to get into Persiaran Mulia. This junction is perhaps the second most congested at peak hours in USJ (after the Kewajipan-Subang Permai junction). The present arrangement makes it very taxing on all road users converging at this junction.

No total stop at the Pesiaran Kewajipan-Persiaran Mulia junction (near Al-Falah mosque)

The next T-junction along Persiaran Kewajipan is the Kewajipan-Mulia junction opposite the Al-Falah moque.

The Persiaran Kewajipan – Persiaran Mulia Junction, taken from Persiaran Kewajipan facing the direction of Taipan USJ.

At this T-junction, traffic on Persiaran Kewajipan heading towards Summit USJ direction (blue arrow) is not obliged to stop. This makes it very dangerous for traffic on Persiaran Mulia (red arrow) on green from the traffic lights to turn into Persiaran Kewajipan. This is most difficult for traffic intending to filter into the junction near the back entrance of Al-Falah mosque as well as for those wishing to turn into USJ 9 Business centre at Jalan USJ 9/5J further along Persiaran Kewajipan.

No total stop at  the Persiaran Kewajipan-Persiaran Tujuan junction

The last T-junction along Persiaran Kewajipan is when Persiaran Tujuan (the other major road of the township) meets Persiaran Kewajipan (at the intersection of USJ 9,  USJ 13 and USJ 14).

In this case traffic turning right at on green light (red arrow) will have to merge with non-stopping Persiaran Kewajipan traffic (blue arrow) coming from Summit /Da Men direction. Thus the right turning traffic has to squeeze over a relatively short distance from the right hand most lane to the extreme left if they intend to enter the USJ 14 via Jalan Mulia which is pretty busy especially in the evening during durian seasons as there are a few established stalls along this road.

Only Tujuan-Bakti T-junction is a no-total-stop on Persiaran Tujuan

If we take a look at the other major arterial road of USJ, Persiaran Tujuan, we will find that out of the 4 junctions (all being T-junctions), only the Persiaran Tujuan-Persiaran Bakti junction (at the intersection of USJ 9 / USJ 13 and USJ 11) is a not total stop junction.

Again for this Tujuan-Bakti junction, traffic from Persiaran Bakti will have to filter quickly into the extreme left lane if they are to turn left into Jalan Usaha to access USJ 17 & USJ 18 where this is a kind for shortcut for USJ resident to access the Elite highway. A complete stop for traffic on Persiaran Tujuan (heading towards Subang Jaya direction) at this T-junction will make it much safer for everyone crossing the Tujuan-Bakti T-junction.

Much safer if there is no not-stopping traffic at T-junctions

The other three T-junctions along Persiaran Tujuan in USJ, namely the Persiaran Tujuan-Persiaran Murni T-junction; the Persiaran Tujuan-Persiaran Perpaduan T-junction and the Persiaran Tujuan-Persiaran Setia T-junction all have complete stop (red icons) for traffic on Persiaran Tujuan when the traffic light is green for traffic at the respective corresponding T-junctions (blue arrows) . Aside from motocycles running through the red light, the flow of traffic filtering into Persiaran Tujuan at these three T-junctions are much smoother and safer.

Make all T-junctions “complete stops” at the traffic lights

It is the opinion of this author, a twenty three years resident of USJ that Majlis Perbandaran Subang Jaya (MPSJ) should seriously consider making all T-junctions at this township “complete stops” at the traffic lights. This may not solve the traffic congestion issue, especially at key areas of bottlenecks, it will certainly make it safer and perhaps even easier for road users turning into Persiaran Kewajipan in order to reach exits along these T-junctions.
