I've just written a summary post which shows how all of the traffic lights in Assen work. This is one of many blog posts about traffic lights.
All of Assen's traffic lights can be navigated in safety by any cyclist. Children can ride safely across all the junctions, as well as across all of the junctions which do not have traffic lights. They can do so using the same infrastructure as provides the most efficient journeys for the most confident cyclists.
Unless design of infrastructure takes into account the needs of all potential cyclists, then it won't serve all potential cyclists.
