Heavy Traffic in Indonesia - Peak Hours

Hi,

What day/s and time should I expect heavy traffic in Jakarta. Your information would definitely help newbies like me.

Thank you.

Every day. All day. Everywhere.
If like me you are in Jakarta then it can take me around 35 minutes to go 16km in the morning to work and just short of hour on the way home. This is on a motor bike.
For a car add 10 minutes to get to work and at least 30 minutes return
In rain then double the return time.

Major road building in and around Pluit, PiK, Kuninghan, All of Sudirman, from Blok M to Ciledug, Permata Hijau, then I think there are still road projects in east of the city but I never go there and the north.
There are over 400 known major traffic jams areas in the city on a dry and good day and the average speed is around 14km on normal roads.

That's all I have to say about that.

Thank you very much for the information. Definitely, it would help. Appreciate it.
