A layout is not "verified" until it survives .
: To avoid a final "Invalid" status, the manager ensured that arriving passengers never crossed back into the security zone. They were funneled through One-Way Exit Gates directly to the non-secure baggage claim.
This is where 90% of "unverified" layouts die. After passing ID, passengers move to the (Where they put their bags).
Never leave your security machines unassigned. If you do, passengers will choose the closest ID stand and the closest bag scanner at random, causing chaos and uneven queues. simairport security layout verified
Never, ever place stairs or escalators to a second floor within 10 tiles of your security exit. Passengers need to decide their gate direction. If they hit stairs immediately, they will stop moving, causing a "traffic jam" that backs up into the detectors. The game still shows "verified," but the system is dead.
For hubs with terminal floors, you must manage security flow across levels.
For the physical placement, a "pass-through" design is highly effective. Position the Bag Scanners so that they sit on either side of a central walkway. The Metal Detectors should be placed in the middle, flanked by the Bag Scanners, much like a real airport. This design ensures that passengers exit the ID Check Stand, drop their bags, walk through the metal detector, and pick up their bags from the other side in a seamless motion.

Inspects carry-on items. Can be replaced with Remote Bag Scanners to save floor space, though these require connection to a Remote Security Station.
Airport security is a critical component of the air travel experience, with security checkpoints being a primary bottleneck in the passenger journey. As airports strive to balance security requirements with passenger experience, optimizing security layouts has become essential. Simulation modeling has emerged as a valuable tool in evaluating and improving complex systems, including airport security.
Build lanes where one queue leads to one ID stand, which then feeds into its assigned scanners. This prevents passengers from crossing paths and getting stuck in "reachability loops". 3. Layout Best Practices This is where 90% of "unverified" layouts die
: Every ID Check Station must have its own dedicated queue line. Assigning multiple stations to a single queue causes AI routing confusion and delays.
Use the assignment tool to restrict the ID Check Stand to these roles only.
: Passengers need an unobstructed, wide path leading directly into the secure zone once they clear the scanners. The Verified Efficiency Layout
| Pitfall | Why It Breaks Efficiency | Verified Fix | |---------|--------------------------|---------------| | | Passengers go to random machines, overwhelming some while others sit idle. | Always assign ID → Bag → Pax in lanes. | | One bag scanner feeding multiple pax scanners | The bag scanner cannot keep up, creating a massive backup. | Use a 1:2:2 or 1:2:3 ratio; never 1:2:1. | | Crossovers between terminals | Passengers take long detours, causing missed flights. | Isolate each terminal’s secure area. | | Placing services in non‑secure area | Passengers have to leave the secure zone to eat or use the restroom, then re‑clear security. | Build all shops, bathrooms, and seating after security. | | Not enough passenger scanners | The bag scanners and ID stands work faster than the pax scanners, creating a bottleneck. | Follow the verified ratios (1:2:2 for metal detectors). | | Multiple ID stands feeding one bag scanner | The bag scanner is overwhelmed, and passengers ignore extra ID stands. | Assign each bag scanner to only one ID stand. |
: The zone was only "verified" once it contained the three essential tools: an ID Check Stand , a Bag Scanner (staffed or remote), and a Metal Detector or Body Scanner .
