Alleviating Congestion at Federal Highway.

I think this would also applies to all other highway.

Some congestion happens few hundred meters before or after a junction or interchanges.

For Federal Highway, the stretch leading to "Motorol junction" from KL, or leading to Jalan 222 from KL is well known to experience congestion.

To reduce the problem, my idea is as below:

1. increase the number of lanes from 3 to 4 lanes (hopefull this could be done).

2. designate the 2 middle lanes  as "express lanes" ,  block any traffic that entering the junction from using it. 

For instance, for "Motorola interchange" from KL, the express lanes should start right before the flyover from NPE (near Cycle-and-Carriage) all the way to Batu 10. It will block any traffic from NPE to enter the express lanes, and from the express lanes into the "motorola junction".

Thus makes the express lanes exclusively for traffic that intended to go to Subang or beyond. 

It will also limits vehicles zig-zagging the highway while exiting the federal highway into LDP,  or entering the federal highway from LDP .

Again, this would be highly effective if we got 2 express lanes, and 2 non-express lane -- with total of 4 lanes per direction.  We might need to experiment with plastic barriers if we are to do it with 3 lane highway.

Any comments?.
