Traffic conjestion in USJ/SJ- problem & solution?

[chsum]

loke, err.. what will happen to the garbage truck, school bus and most important fire engine....

[pcyeoh]

They offered to do that when Chris Fletcher complained to them why weren't they enforcing the 5 ton limit. BTW, MPSJ cannot enforcement traffic rules except illegal parking that are committed where they have designated parking lots. Other than that, it is only the police and JPJ that are the enforcement agencies for traffic offences. The gantry that you are talking cannot be placed across a public road. They are deemed to posed a danger to unsuspecting road users driving heavy vehicles. As chsum said, it will also prevent those vehicles he mentioned from accessing the area here where their services are most welcomed. We may have to think of another solution.

I remember that there used to have a steel barrier across the road atop of Petronas pipeline to prevent heavy vehicles, about 10 years ago.

Should we restore the steel barrier and this will prevent all heavy vehicles to do short-cut from USJ12 to USJ16/17/18 and vice-versa? My two cents!!!

ivanhow,
Personally, I do not think the "KFC-junction" is the problem. I do agree that there is a bottle-neck when 4 lanes squeeze into 2 before joining the Federal Highway, but the traffic really backlogs due to the congestion between the ex-Subang-airport junction and the ex-Motorolla (now Freescale) junction.

The real solution is to remove the bottle neck at BOTH those junctions. Sammy Velu said it once a long time ago (I remember it quite well, despite age taking it's toll on the memory) that the Federal Highway should be at least an 8-lane highway. Whilst this is possible at the ex-Subang junction, the area around the cable bridge at the Freescale junction is impossible to expand.

I agree with KW Chang to some extent, that the source of the problem seems to be blown back from Old Subang Airport Road/Fed Hw point, and the Sunway cable suspension flyover (at Freescale). And also the narrowing to two lanes at the exit into Fed Hway. Perhaps we can still include this into our list, and when we come to prioritizing, the weightage may be not that high, and at least we have it covered. Going forward, with the completion of the NPE-Extension, the flow of traffic into this exit may be so smooth from the NPE/Subang Utama that this exit may find build-up faster than it can take. Just a thought.

Err...this might be true in the case where Petronas may want to avoid any untowards incident where any possible excessive heavy movement of the soil foundation of the 2 x 36" underground LPG Loop1 & 2 might cause the pipe's welding joints to rupture n spring a major LPG leak...

But having to build the barriers before or after the pipelines would not be suitable...coz drivers of such heavy trucks might be caught by surprised without prior warnings on or before the entrances to Jalan Usaha...ahem...imagine the trucks getting stuck near to the pipelines from both ends...

Err...having said that...to prevent heavy trucks entering into or coming out of Jalan Usaha(Hicom-Puchong LDP junction)...it might be best to just built ONE BIG barrier at the entrance from Hicom-Puchong LDP with ample warning signs of it prior to the entrance junction from Hicom...or to prevent heavy trucks from using that junction to exit from Jalan Usaha to Hicom-Puchong LDP...

This way...for those trucks that need to service USJ16/17/18 areas like the smaller fuel tanker truck(instead of larger n heavier tanker trailers)...n other service trucks or buses for this particular areas could access from Persiaran Tujuan or Persiaran Kewajipan...

Whenever we talk about Subang Jaya/USJ traffic issue, 3 critical areas cropped into my mind - the horrendous traffic flow in Taipan, the crazy congestion between the traffic lights at Giant/Kesas and not forgetting the infamous Jalan Usaha.

We need some help on describing the "Taipan problem". Which part of Taipan, and is it through-out the weekday or only certain hours of the day? Or it occurs only on weekend-Saturday? When I visit Taipan during weekdays, I don't seem to see congestion - perhaps it is on lunch hour only?

This continuous flow of traffic throughout the day and night are vehicles taking a short cut through from Jalan Hicom-Puchong (south) to the Federal Highway and lately to NPE. This is a narrow dual carriage way cuts through the residential areas of USJ 16, 17 and 12 to Jalan Tujuan and is not meant to be a main road. This is made worse when heavy vehicles which disregards the 5 ton limit pose great danger road users.

Let's add in the Jln Usaha delimma to the list. This may be categorized under a "Invasion of peace" or something grouping? Trying to understand the "Taipan problem" in order to categorise it. If it is a Saturday banking day problem, maybe we can categorize it under "Taipan Banking Day Conjestion"?

The other traffic junction congestions could be categorized under a group "Morning Rush Hour Traffic Congestion". Any disagreement?

The Giant/Kewajipan junction is part of the "Morning Rush Hour Traffic Congestion" and partly "Highly densely populated" or "Insufficient Exit" category? Any comments?

The need go categorize them will be obvious, as they belong to a class, and the solutions to each class has some commonality. If you already have ideas of how the problem can be solved, they are also welcome at this stage although we are not yet into it.

Keep them coming!

I would like to add these two problematic entrance/exit during peak hour:

Morning Peak Hour
- Something has to be done on Persiaran Tujuan (left turn into USJ 4/1 or USJ 3 before Kesas's bridge towards SS19).

Evening Peak Hour
- Cars coming out from SS18/4G and joining Jalan Tujuan or heading to SS19 really causing lots of backlog in the evening when these cars (bus is the worst) are trying very hard to squeeze into Jalan Tujuan.
- I would suggest (if closure of it is not possible) to install traffic light and timing to be same as those coming out of SS19 (from Lick Hung).

[pcyeoh]

This is the location what jonaChong is referring to. The problem occur only in the evening where traffic coming out from Jalan SS 18/4G have no opportunity to blend with the heavy traffic flow along the main road. The situation is made worst when some of these people cut across the 3 lane Jalan Tujuan trying to turn into Jalan SS 19/6 which is only a 50 metre dash. Installing another traffic light here will not solve the problem as many road users in Subang Jaya are colour blind. They will jump the lights and block these people. Adding another set of traffic lights here will make this place look like a Christmas tree. The best solution is to make it a No Exit point here. These vehicles can use the Jalan Jengka and Jalan Subang Utama as an alternative.

So, let us include this as one of the cause of traffic congestion in the morning as ppl sending children to school. Agree?

How nice if we can get easy traffic flow like this whole week (school holidays)......everyday...

So it means that the traffic jam every morning partially is caused by school going children. If we noticed in the daily jam, mainly one car will only has one child and a parent.

Any suggestions to reduce this?

One of the cause of traffic congestion in the morning is obviously ppl sending children to school - yah?

I noticed that the Wawasan School in USJ 15 is a very well planned school with lay by and proper roads leading to and away from the school. But I have not been to that school during the start and the dismissal time to observe whether the design causes any traffic chaos. You notice that ALL schools suffer from the same fate. It is worst when the schools are being built smacked in between houses. The school planners should learn from these mistakes. The mother of all such jam is found in Lick Hung School area. Everyone cares for himself and herself only.

[kwchang]

Lick Hung is an exception to the norm.

Picture this -
50 students per class,
at least 12 classes to each of the Std.1, Std.2, ... Std.6 levels,
6 Standards or levels in the school

So you end up with something like 3,600 kids.
Fortunately, this school is broken up into 2 sessions -
4 Stds in the morning = 2,400 kids
2 Stds in the afternoon = 1,200 kids

Remember at midday, it is mayhem becoz the morning session kids gets picked up while the afternoon session kids get dropped off.

[JoeJaffar]

Not just Lick Hung, the SK SS19 next to it shouldn't have been built there. 2 primary schools sandwiched between shoplots, a mosque and flats. Add parents, teachers, shop patrons and owners, passersby to the equation, that's how we'll reach to a chaotic traffic condition.

[chsum]

This is my indecent proposal rival to that of Patrick really indecent proposal.

Build more school to solve traffic jam problem

--------------------------------------------------------------------------------

Did any of you notice the stressless journey to work in the morning and sometimes in the evening during the school holidays, I was wondering why can't we have that the whole year round, I don't mean to close all the schools, but instead of having 2 session (morning & afternoon), why not 1 (like in most develop country) and make the school hours let's say between 10.00am to 4.00pm so that the school traffic won't clash with the office going traffic, set down rules, so that no school bus allowed on the road b4 9.00am and after 5.00pm.
Let's make a rough calculation, how much to build a new school (10mil?), how many school needed (2,000?)
How much to upgrade all the roads in Klang Valley? anyone?
How much time wasted on the road? For me, I halve my travel time during school holidays.
I am sure someone have come up with this idea before, why was it not bought to the attention of our education and transport ministry?

[Firefly]

Either SMJK Lick Hung have to go or SMK SS19. The question is why does SS19 have 3 primary schools? If you do not know, SMK SS17 is also in SS19.ironic is it not? And both these SS19 and SS17 have only a single session. Maybe these 2 schools should me merged into 1 and the whole SS19/6 area given to SMJK Lick Hung.

[Firefly]

Anyone toying with this idea? one way system? Say One way across kewajipan into USJ and one way from USJ across Tujuan. Then all the stupid traffic lights can be dismantled.
