Smart Traffic Signal Simulation for an Urban Junction

A simulation project that changes signal timing based on traffic demand and queue length.

Project objective

Create a traffic signal timing model that adjusts green time according to vehicle count or queue length at an intersection.

Suggested materials or data

• Intersection layout
• Manual traffic count data
• Excel, Python, or web simulation
• Optional Arduino LEDs model

Step-by-step workflow

1. Collect traffic count by movement and time interval.
2. Calculate existing cycle time and delay approximation.
3. Build simple rule-based adaptive signal logic.
4. Compare fixed-time and adaptive signal scenarios.
5. Visualize queue and delay reduction.

Minimum deliverables

• Traffic count sheet
• Simulation model
• Signal timing comparison
• Mini LED demonstration optional

How to make it stronger

Build a small physical LED junction model controlled by Arduino.
