Bus Traffic Fever Level 315 Answer & Walkthrough Solution

Quick answer

Level 315 features a massive, tightly interlocked parking grid beneath a continuous passenger queue. The key strategy is managing your five parking bays carefully during the opening moves: several small buses (brown, red, and purple) must be staged in reserve bays to open pathways for full-sized buses. Avoid completely filling all five slots with waiting vehicles—always keep at least one bay cycling by matching the active colors in the queue, then clear the staged buses as soon as their passengers arrive.

Tips for success

• Patience with staged buses: Do not panic when small buses sit idle in slots 1, 2, or 4 for several minutes. They hold low capacities (4 passengers) and will clear instantly once their color cycle loops around.
• Keep slot 1 rolling: Always make sure at least one parking bay stays open for the exact color currently at the front of the passenger queue.
• Pair-tap matching vehicles: When a passenger group exceeds the capacity of a single vehicle (e.g., 24 passengers when a bus only holds 12 or 16), pull the second vehicle of that color into an adjacent bay immediately so the line never stalls.
