Green waveoftraffic 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 wavea good co-ordination of signals makes a green wave 40 s 80 s 45 km/h 40 s cycle time 0 s 500 m
500 m Green wave for both directionspossible only if the cycle time, speed and distance are OK 40 s 45 km/h 80 s 45 km/h 40 s cycle time 0 s
250 m 250 m Uncontrolled junction in the middlecrossing the street impossible because of the continuous flow 40 s 45 km/h 80 s 45 km/h 40 s cycle time 0 s
250 m 250 m Green wave stops twice in the secondary directionbut in the main direction the progression is good 120 s 40 s 60 s 80 s 40 s 45 km/h cycle time 20 s 0 s
250 m 250 m The green wave stops once in the both directionscompromizing the green wave progression 80 s 80 s 45 km/h cycle time 20 s 40 s 0 s
250 m 250 m Half of the cycle timeside street green is absolutely too short 45 km/h 40 s 40 s 40 s cycle time 40 s 45 km/h 15 s 0 s
250 m 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 40 s cycle time 0 s
250 m 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 250 m What about the SYNCHRO optimization it brings minimum delays ands stops for vehicles 80 s 45 km/h cycle time 0 s
”A good but forced green wave” pedestrian must wait on refuge, vehicle must turn on right 40 s 80 s 45 km/h 40 s cycle time 45 km/h 0 s 250 m 250 m a right turn to the right only
Green wave for Mannerheimintie in HelsinkiHere 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... 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.
