Stop getting run over by those passenger-transport golf carts in airport concourses with this one incredible tip, brought to you by the Big Laser Pointer industry.

Background:

Airport terminals often have small golf-cart-like trams that can be driven around in the passenger concourses. These are often used to help people move around the concourses (for example, one might be used to help a passenger with a leg in a cast who is trying to make it to a connecting flight).

The issue:

These passenger carts can move quickly, and may run over pedestrians in the terminal. To help prevent this, the carts usually emit an incredibly loud and annoying beep (like a truck backing up).

However, it is usually not very obvious where a cart is based only on the annoying beeping sound, especially in a crowded concourse (Figure 1).

Fig. 1: The annoying beeping coming from this airport golf cart lets people know that a cart is nearby, but requires pedestrians to 1) find the cart and 2) figure out what path the cart is attempting to take through the airport crowds.

 

Proposal:

Instead of only beeping, the passenger cart could also have a special set of headlights that would project a “danger zone” image in front of them. This would make it extremely obvious as to where pedestrians should not walk.

Fig. 2: This updated passenger cart has special headlights that project a “danger zone” region in the path of travel of the cart. These headlights could be repurposed laser pointers with a more spread out pattern (instead of a single dot).

Conclusion:

These new headlights could be an after-market attachment, since most airports will probably not want to replace their existing fleet of golf carts.

The light would only turn on when the shuttle is moving and would only consume as much energy as ~10 handheld laser pointers, so it shouldn’t substantially reduce cart battery life.

PROS: Would make it much easier to avoid being run over by an airport carts.

CONS: Probably… none? Is this a legitimately good idea?
