On the North side of the Vaart in Assen is a bicycle road which has no traffic lights on it all the way into the centre of the city. That's the primary route in this direction.
Today we're on the Southern side of the same canal, on a secondary cycling route, which has this one set of traffic lights for cyclists.
There are a number of interesting things here.
The parallelogram features on the ground are the second set of detectors for bicycles which you roll over on the way to this light. The first set is about 50 metres before the lights. It is advantageous to cyclists to have their own detectors as they are never set up so that they only detect cars. Having the double set means that often the lights have changed for you before you reach them.
There is also a yellow button on a post which allows a cyclist to make sure that the traffic light controller is aware of their presence. If the detectors should fail, then this gives another way of indicating the presence of a cyclist.
Next we have the green sign on the traffic light post, which indicates this is a simultaneous green junction at which cyclists can go in any direction they want (left, right, straight on, diagonal) when there is a green light. All motorised traffic is at a standstill while this happens.
Cyclists are never given a green to cycle straight on while drivers have a green to turn right. To do this would put cyclists into the most dangerous and lethal position on the road.
Also note that you can see lamps on the lampposts ahead over the cycle path as well as over the road. This helps to improve the social safety of this cycle path at night.
Finally, note the width of the cycle path. It's over 3 metres in width, even though it's merely a secondary route paralleled by the 5 metre wide bicycle road on the other side of the canal.
This is proper cycling infrastructure which attracts cyclists, designed for a high degree of actual and subjective safety. It is part of what has resulted in Assen having 41% of all journeys by bicycle - a higher cycle modal share than can be claimed anywhere outside the Netherlands.
