The Sand Glass is a new look at traffic lights. Surely people must be frustrated with the current design of a regular traffic light, which is why we have seen THREE DIFFERENT DESIGNS recently. Make this the fourth dimension using the sand-hour-glass as its model. LED lights trickle down to make an obvious statement, regarding the time left for the lights to change, making it easy and intuitive.

User Story #1:

There was a local businessman working for Apple called Al. He was running late because he accidentally woke up late due to a malfunctioning alarm clock. Realizing the time, Al jumped into his car when he raced out of his driveway and drove as fast as a high speed bullet train. While driving, he saw a red light and had to stop, but thankfully for him, he didn’t have to wait long. As soon as he slowed down slightly, the hour glass-shaped traffic light had 3 seconds left on the clock and then turned green. Al was relieved and sure that he would be able to get to his job over at Apple on time.

User Story #2:

There was a couple named Jon and Alice. They were driving off to their honeymoon alongside Newport Beach and stopped at a red hour-shaped traffic light. Alice told Jon to send a message to their friends and family to let them know how they were doing, so Jon took out his phone and texted away. While he did that, he didn’t notice the light was on the yellow portion and the sensors picked up that his hand was not on the steering wheel, so it shot out an acrylic paint ball onto his car to attract his attention. Jon quickly realized this and then drove off when the light turned green. So after they finished their honeymoon, Jon downloaded an app that when he uses his phone, it lets him know if the signal will turn green.

Our Mission

Our mission is very simple: while we want to have efficient 'sand' lights to help ease back the traffic, especially in areas prone to have traffic jams, we also want to practice safety and attentiveness to prevent delays. Adding an app onto your phone will certainly enforce this quite a lot.


The LED Traffic Lights were inspred from the hour glass, one of the original forms of taking time that we’ve used for over a century. It’s easy to see the light’s color and estimate how long to wait or hurry to go obviously from dropping pixels interfac like a real sand glass. The countdown number, 3-2-1, appears only while the “sand” on the yellow light’s turn to warn that the color will change to either red or green in a few seconds. That is the reason for the overall Sand Glass for communication design for everybody.

That’s not all, because it’ll include a sensor that if someone has their hands on something besides the driving wheel, an acrylic paint pellet will shoot on the front of the car to get their attention. That’ll be an effective way to get someone’s attention and not have to clog up traffic anywhere. That sensor can also be used as an app on someone’s phone and when the countdown is completed, the app will send a 10 second warning to put down the phone or be reminded the hard why people should pay attention.


Traffic control signals date back to the 1860s and have evolved very little since computers took over American traffic lights in the 1950s. Traditional signals include a red light to indicate the driver to stop, a yellow light to yield, and a green light to tell the driver to go. The irony with this device is that this innovative digital hourglass represents a historical time piece that dates back centuries. Today in 2100, these hourglass traffic lights will help improve traffic safety for years to come!
