Green wave of traffic signals ”Why on earth you can’t plan such a co-ordination for traffic signals, that you need not to stop every time in everywhere...”

Principle of the green wave a good co-ordination of signals makes a green wave 45 km/h cycle time 40 s 0 s 500 m

Green wave for both directions possible only if the cycle time, speed and distance are OK 45 km/h cycle time 45 km/h 40 s 0 s 500 m

Uncontrolled junction in the middle crossing the street impossible because of the continuous flow 45 km/h cycle time 45 km/h 40 s 0 s 250 m

Green wave stops twice in the secondary direction but in the main direction the progression is good cycle time 45 km/h 40 s 20 s 0 s 250 m

The green wave stops once in the both directions compromizing the green wave progression cycle time 45 km/h 20 s 40 s 0 s 250 m

Half of the cycle time side street green is absolutely too short 45 km/h 40 s cycle time 40 s 40 s 45 km/h 0 s 15 s 250 m

Slow down of the green wave ”in real life nobody will use such a speed” 22.5 km/h 80 s 80 s 22.5 km/h cycle time 40 s 0 s 250 m

Green carpet ”the last vehicles of the green wave will cut of” 45 km/h 80 s cycle time 20 s 45 km/h 0 s 250 m

What about the SYNCHRO optimization it brings minimum delays ands stops for vehicles cycle time 45 km/h 0 s 250 m

”A good but forced green wave” pedestrian must wait on refuge, vehicle must turn on right 45 km/h cycle time 45 km/h 40 s 0 s 250 m 250 m a right turn to the right only

Green wave for Mannerheimintie in Helsinki Here is the green wave, plan the opposite green wave, too 40 km/h 90 s 55 s cycle time 0 s Erottaja Lasipalatsi

Timing of Traffic Signals Timing of Traffic Signals ... is making compromises and balance in different directions and periods between buses, cars, pedestrians, delivery vans, cyclists, trams lorries, roll-skaters, taxis, children and pensioners, blind and invalid people and other citizens’ wishes and demands.
