I think this is not an old issues, just cannot understand why it never get it right the first time.
I have been using Jalan Loke Yew for some weeks, the road is now widen from last time 2 lanes to 4 lanes now, especially the stretch along UE3 complex. But when the stretch finish, where it go up the fly-over, basically it is from 4 lanes to 2 lanes, hence the long queue jam. Worst when the 3rd and 4th lanes suppose to allocate for these car want to turn into the cheras round about, either to jalan cheras or to HUKM, apparently manage cars occupined this lanes, and when come near to the end, they will try their luck, some, or just forcefully go into the 2 lanes flyover, there are not so many cars who is actually turning into jalan cheras round about, I think everybody will know the malaysian style of driving, if you can cut queue, by all mean do it. Sick of it sometimes.
I would like to suggest the authority, either DBKL or traffic police, i think is fall under traffic police, to put the barried far before the fly-over to prevent these car from jumping from 3rd and 4th lanes into the fly-over. We have implemented the cut queue rules and some got the fines when initially it was implemented, as usual, thing or enforcement is basically "hot hot chicken shit"..after a while no body care anyway. So at least learn from smart tunnel, they will put up the sign board to remind you to go into the right lanes, and they also put some barried some distance from the Y junction. Of course there is still some driver tend to cut into jalan tun razak lanes from jalan ismail, and one in a while you will hear some horn..fact is we will never get rid of this kind of drivers anyway, if yes, it will take another 10 to 20 years for education for next generation, hence some measurement is needed to do the hard prevention.
Working in KL is stressful, not due to work, but due to traffic..but i am glad i am not driving in jakarta..could be worst
