  TrafficSense prototype

Inspiration

Our own frustration with long wait times at red lights despite no oncoming traffic.

What it does

It monitors the traffic flow in an intersection and changes the traffic lights accordingly to reduce wait times.

How we built it

It was built using C++ and an Arduino, as well as various components, including LEDs, buttons, and ultrasound sensors.

Challenges we ran into

Some challenges we ran into include being unfamiliar with using an Arduino and breadboard, as well as integrating the two buttons and coordinating the timing between the two traffic lights. We solved the first challenge by seeking help from a WallyHacks mentor, and we solved the second challenge through trial-and-error, problem solving, and creative thinking.

Accomplishments that we're proud of

The accomplishment that we're the most proud of is coordinating the traffic lights and getting them to switch between the timed-algorithm and the induced algorithm.

What we learned

We learned about brainstorming and prototyping sustainable urban solutions using Arduinos and breadboards.

What's next for TrafficSense

Our next steps would be to scale up the prototype to mimic real-world usage.
