So you are advocating reducing the number of passengers per bus and increasing the number of buses to reduce congestion.
No - this is just a lack of space given to buses for bus stops
Except most dense urban corridors that really be bus only at peak times, tunnels, CBD's.
There are many papers out there on the benefits of giving priority to buses. Just because HK policy is stuck in the colonial era of focusing on the MTR does not mean it is a good policy. ALL other developed cities have improved their policies for at grade mass transit. HK has seen no changes for 20 years. Poor governance.

Interestingly even though HK has the most bus users it is left off this best practice study for international cities.
