BRT is a tested concept in Jakarta and Guangzhou.
Federal highway is already very congested, but many of them are in private vehicles rather than public transport. Public transport is more efficient, but doesn't work at this moment because buses stuck at the same traffic spot as other vehicles on the highway.
With BRT, buses can finally have their own lanes, increasing the speed and reliability of buses, and that will make commuting using bus even more convenient, reliable and fast.
Sometimes, I still do not find the logic of opposing it, because federal highway will always get jam and if there is nothing to be done, it will get even worse.
At least with BRT, bus will be a lot faster, at the same time, capacity of public transport along the corridor will be much higher.
