"The main problem in my opinion is that the exits and entrances into the expressway are too close together which causes the bulk of the bottle necks and jams."

If you spread the exits & entrance far apart, you seriously think the bottle necks & jams will be reduced? This is like no difference from thew ERP game, just reshuffling the jams & bottle necks from place to place.

It will be reduced. Because cars exiting and cars entering the expressway are criss crossing each others lane. The other way is to have exits BEFORE entrances.

NSH. 3 Lanes only. quite clear for most of the time. Everyone is courteous and gives way to faster cars.

try sle towards tpe in the morning when im there around 645-715 timing. there are always road-hoggers at 90kmph on lane 1 starting from woodlands ave 2 right up to after thomson flyover where at least the sle branches into 5 lanes (including one for yio chu kang exit). dats when fast cars can overtake from lane 4. wat a joke.

in addition, lots of cars filtering into sle from woodlands ave 2 and straight away head into lane 2, going at 50-60kmph. there are even idiots coming into lane 1 at dat speed and yeah, same idiots who then hog the lanes as mentioned above. fckers never move. when i come up behind them, i put my right signal. wait a while, then i high beam. wait a while, then i tail-gate. wait a while, then i horn. finally, i do all of them and still no one give way. geez wtf are the tp when u need them? too early for them?

lots of lorries and vans on lane 2.

The best connections and I think the best only should be the one where KJE joins PIE. That is the only connection that doesn't create bottleneck traffic like other expressways in Singapore. To me, ERP is a failure and is implemented by someone who doesn't know Maths, because cars are just like flow of water, no matter how you block, the water will divert the other way to continue its flow and the volume within the same space is still the same. ERP is only good in filling up $$$ and nothing else.

like what heartbreakkid mentioned, the person who thought that ERP will solve traffic jams obviously has no idea what traffic engineering is about. i bet he or she doesn't even have a clue with regards to fluid mechanics. Look at the major interchanges between the expressways.

They are a joke. Seriously, if you expect a 3 lane-(merging to)2 lane- (merging to)1 lane road e.g. PIE> CTE(SLE) @TPY to serve as an arterial road linking two major expressways and expect that it will suffice, i think we might have better prospects watching pigs fly at Mach 2.

In a nutshell, you can widen the expressways to 10 lanes and still the jam will occur. Simply because the traffic bandwidth is only as wide as the section with the lowest traffic throughput.

do u tink tat those scholars and high paid ppl up there will even take a look at wat ppl down here are tinking???

I thought 90kmph is the limit and how can that be hogging? I fail to understand here..
