Traffic Lights

 Traffic Light Exercise 

The Traffic Light Exercise asks you to explain how traffic lights work at a interstate in a flow chart, simplifying the task by state there are no pedestrian crossing lights and no filtering turn off point. I did this exercise in a pair and one thing that quickly became clear to us was that as much as we knew how traffic lights worked we weren't sure how to put that down in a flow chart. When it came to the solution we decided to take the problem from the prospective of the driver as they approached the lights.

While the solution we came up with wasn't inherently wrong it was not the solution that was requested.
