Actually, considering Bukit Panjang Bus Interchange has 20
parking lots and 2 feeder services, it can only accommodate 4 trunk
services.
This is because 2 feeders would require 8 parking lots (1 feeder
- 4 parking lots). The remaining 12 parking lots can only
accommodate 4 trunk services (1 trunk - 3 parking lots).
Yet, there are 6 trunks: 176, 970, 972, 973, 975, 979.
Can consider relocating 972 and 973 to the temporary bus
park.
