> The location of the lights doesn't exactly point to usage by cyclists.

It depends on the city, but unless you're on the highway or about to enter one, a traffic light here can be assumed to serve bikes.

I found that link a few years ago thanks to an app I used when I went to university: https://www.enschedefietsstad.nl/enschede-fietst-app/snel-gr... The municipality has an app that will integrate with the iVRI system to have traffic lights turn green faster for bikes. It doesn't do anything for cars, it's built purely to try to convince more people not to travel by car.

Of course, iVRI data providing information about incoming bicycles don't automatically reprogram traffic lights to give them priority. However, the information is available. I've had the Enschede app trigger a "this app requested X green lights during your ride" popup in other cities; I'm pretty sure it's just an iVRI integration, not one restricted by a specific municipality.
