Steps
- Build a scale intersection on foam board with LED signals on each approach.
- Place sensors to detect cars waiting on each approach.
- Program fixed timing first and measure average wait time.
- Program adaptive timing that gives green time based on detected traffic.
- Compare delay between fixed and adaptive timing.
- Film the demo and document the results for your portfolio.
