Solution

To solve this problem, we propose the installation of LED floor lights to guide customers into two lines. These lights will be added in two sections: two lines in the front, and one line in the rear.

The purpose of these LED footprints are manifold:

1. To guide the first customers into one of two lines. When no customers are in line, the lights will flicker softly green to attract their attention.

2. To indicate to later customers when a food station is open. Pressure sensors in the front LEDs will track the number of customers in the front of each line. The LEDs will then display blue (low traffic) or red (high traffic) to indicate to customers whether or not they should move up.
