What's more, cyclists usually get two green phases per complete sequence of the lights, meaning that they wait for less time behind a red light. This leads to cyclists getting past the lights quicker than drivers. It works very well indeed.
A couple of days ago I made a video of riding across such a junction when I visited Groningen. Also there is a video of the same junction made by the fietsberaad, the Dutch panel of experts in cycling, which demonstrates the same junction from different angles.
Please also read other later / better blog posts about simultaneous green traffic lights. Also see many other examples on this blog of infrastructure which makes cyclists' journeys faster.
