Signal Timing Optimizer Skill

Purpose

The Signal Timing Optimizer Skill optimizes traffic signal timing including cycle length, phase timing, coordination, and pedestrian timing per MUTCD requirements.

Capabilities

• Cycle length optimization
• Phase timing calculation
• Coordination timing (green wave)
• Actuated signal design
• Pedestrian timing (ADA compliance)
• MUTCD compliance checking
• Clearance interval calculation
• Ring and barrier diagrams

Usage Guidelines

When to Use

• Designing new signals
• Optimizing existing timing
• Coordinating signal systems
• Evaluating pedestrian access

Prerequisites

• Traffic volumes available
• Intersection geometry defined
• Phasing established
• Speed limits known

Best Practices

• Verify clearance intervals
• Consider pedestrian needs
• Test coordination plans
• Document design decisions
