Can not be denied again, the existing congestion in the capital has become a byword for some time. Many causes which make all those thing happen.
Such as flood,this is one of cause why capital jammed. Many program to solve this problem, and also goverment has done his best. But what we see now these thing happen again.
The second is too many vehicles in capital will cause jammed. It will be better if goverment reduce and make a limitation vehicles.
