1. Extension of green light in anticipation of the platoon2. priority green in anticipation of the platoon3. Brake off the green light at other directions and
priority green in anticipation of the platoon
Give other directions green light first, in anticipation of the platoon

Evaluation:
• Chance of stopping in mainstream - 10 - 40%• Total of waiting time mainstream max – 50 %• Total traffic delay network max - 25%• Duration of traffic jam is shorter• Outside the rush hours: no priority interventions • Helps on meeting your multimodal network goals
