# Traffic Simulation Engine Skill

## Purpose

The Traffic Simulation Engine Skill performs traffic analysis including microsimulation, level of service calculation per HCM methodology, and signal timing optimization.

## Capabilities

- Microsimulation modeling
- Level of service calculation (HCM methodology)
- Queue length estimation
- Delay analysis
- Signal timing optimization
- Trip generation calculation
- Capacity analysis
- Intersection performance

## Usage Guidelines

### When to Use
