Right turn only lanes

This must have been one of the best example of poorly designed junction and lane markings.

During morning rush: most traffic is going to turn left towards lornie highway. The traffic light signal is designed such that when left turn arrow is green, the go straight arrow is red.

You just need one car going straight on 2nd lane (go straight or left turn) and you will get a back up cars wanting to turn left stuck behind that car and many will try to change lane to the moving 3rd lane.. Often times taking huge risk and depending very much on the other cars slowing down just to give way to them. 

During non-peak hours like weekend, most cars will turn right towards upper thomson road... And since there is only 1 right turn lane (1st lane), the queue form up all the way back to the junction before.... Many will try to jump queue by taking the 2nd lane and making an illegal right turn endangering others. 

 

 

Took a video yesterday during morning rush hour to highlight the situation when the dual purpose lane is blocked due to poor signal and lane marking optimization:

Without a human directing traffic, no way the infra can handle either extreme.

why not?

Just use the 40mil to embed LED lane marking (dual purpose) that is married to the a display board that shows the direction of each lane during certain segment of the day. the traffic signal timing is also integrated into this system.

that is real smart nation with real solution...not some slogan shouting by the LTA scholars and ministars

The problem is not infra.

Rather, it is our drivers.

Regardless how smart the infra is, 1000% got KNN drivers.

That’s why TP on site to manage the traffic will eliminate KNN situation.

Such shared lane is everywhere at traffic junctions lo. And poor signal is also the same at every traffic junction. But LTA still never find this is an issue at all, even you feedback to them.

IMHO.
If not how to say Singapore traffic always got jam and fiddle with COE ??  🤣

And the ERP. Jam because of the combination of poorly designed intersections, bus lanes and drivers not signaling their intentions early. Solution, implement or raise ERP. 

Some roads are naturally free-flowing. But still have jams because too many level signalised pedestrian crossings that are not coordinated with traffic junctions ahead. Traffic gets held up for a single pedestrian while the traffic junction is green with no cars able to pass. Commonwealth Avenue towards Clementi is an example.

This type of junction needs TP to direct traffic due to its extreme nature.

LTA “knows” any change will not fix it.

Confirm got KNN drivers

The turn right on green arrow only that's rolled out to a lot of junctions recently also causing much longer waiting time for all(pedestrians and vehicles). Longer queues at more junctions for turning right, sometimes got to wait for next green arrow for your turn when in fact the roads are clear.

While it's for safety purposes but If they roll this out, it should at least be a "smart" traffic light, not fixed timing.

So as usual LTA ''knows'' the issue but ignore and let the issue like this forever.

Unless you want to be the human traffic controller

Very good video and precisely my point. They think that the problem will be reduced if they convert lane 2 to right turn only. It won't.

I guess it is not productive when you have dual purpose lane, especially when there is a change in traffic singaling. Cars wanting to turn right would have been stuck if the car in the front row is goomg straight and vice versa. 

But but but, I song song drive the outer most lane suddenly kenna a long row of cars turning right (most Singaporeans don’t signal their intention) coupled with only turn on green arrow only. The lane become terribly congested. 
 

Also anyone often drive Serangoon Gardens roundabout. The recent change to keep left to turn left/straight and keep right to exit right. Since our scholar implemented that I’ve witness afew accident and near misses. 🤦🏻‍♂️

I agree. This is absolute stupidity, why do we need 2 right turning lanes with few cars using it?!?

Am sure there are many of such cases islandwide after the recent changes. Each adjustment in lane usage ought to be done with traffic impact assessment. Alamak, just count the number of cars going straight vs turning right. 

Because it's a vicious cycle.

1. Root cause is stupid drivers cannot right turn properly and causing more accidents.

2. LTA stupidly implemented controlled right turn at every junction without analysing each junction unique situation.

3. But controlled right turn then cause more congestions due to longer queues and stupid dreamers not moving off fast enough.

4. So again LTA stupidly implementing even more right turn lanes to fix the problem they created themselves.

The only thing they should've implement at every junction is red light camera but they didn't sigh.

That’s why Singaporean deserves to be car-lite.

Controlled right turn is safer but if after implemented this, they must also cater longer timing for cars to right turn. But too bad they never lo, this is why it causes more congestion.

Noticed the green light timing given can be as short as 10 seconds but averagely not more than 25 seconds.

I see most have been adjusted to be longer, so far can cheong through even if i'm far behind

Think only when you feedback to them then they adjusted the timing slightly longer la. But overall still quite short like 15 sec. Super annoying when doing right turn nowadays.

15secs is very short when the cars in front are dreaming and/or afraid to rev the engine for a quick pick-up. Very often when the arrow comes on, the first car takes 3 seconds to move off, and slowly. The second car follows suit.

Singapore driver trait: Very slow to move off, but cheong to pass amber and even red lights.
