What is a unique feature of the Blue Stripe pathways?

The unique feature of the Blue Stripe pathways is that they are color-coded for easy navigation. This design element is particularly crucial in large and busy environments like O'Hare Airport, where travelers can easily become disoriented. The color-coding helps passengers quickly identify their location and the direction they need to go to reach their destination, enhancing the overall travel experience. This systematic approach reduces confusion and assists with efficient movement throughout the airport, making it simpler for travelers to find their gates, terminals, or other facilities.

While the other choices mention useful amenities and services that might exist at the airport, they do not specifically highlight the distinctive purpose of the Blue Stripe pathways in facilitating navigation.
