Traffic Signals

• Separate conflicting traffic

• Assign right-of-way• Increase throughput • Reduce delay• Improve safety• Provide progression

through network• Help low volume

roads

Signalized Intersections

Pre-timed Actuated

Types of Traffic Signal Control

Based on historical traffic volume

e.g. PM peak will all have same

green and red time

Semi-Actuated

Detect presence of vehicle in time and space

Make a decision to allow traffic to flow
