Bus Traffic Fever Level 188 Answer & Walkthrough Solution

Tips for success
- Clear Outer Lanes Early: The small buses on the left and right borders are unimpeded; sending them up when their color matches frees up visual space and starts boardings immediately.
- Respect the Tunnel Directions: Horizontal buses can only slide towards the arrow direction on their roof. Always make sure the target vertical track (left or right) is clear before tapping them.
- Balance Both Exit Tracks: Avoid sending multiple vehicles in a row into the same vertical track if the other side is open, as this prevents traffic bottlenecks.
- Queue Awareness: Keep at least two top parking bays free by ensuring the vehicles you release directly match the front group of the snaking passenger line.
