The Indonesian government will introduce 'one way' and 'contraflow' systems during the upcoming holiday period (Isra Miraj and Imlek) to alleviate traffic congestion. The 'one way' system will be adjusted by police based on real-time traffic conditions, while 'contraflow' will operate for specific hours on the Jakarta-Cikampek and Jakarta-Bogor-Ciawi routes. These traffic management measures are essential to ensure safe and convenient travel for the public.
