Axiata concert only is not many people .... its the big stadium of 50k to 80k people like coldplay that cause havoc.

All the roads surrounding the stadium area will become car park, people park on curbs, along roads, etc .... not sure if got saman, but sometimes police will block certain roads to direct traffic after concert ... so they not bothered about saman i guess. People will walk 1 to 3 kms to their cars outside compared to inside stadium carpark which is stuck bottle neck.

LRT also will be jampacked and queueing ... speaking from coldplay and taylor swift reports... can see pics and reports

Good luck ... haha
