Oakland County is a county in the state of Michigan with a population of 1.2 million people and has an area of 908 square miles.

Colored dots = Adaptive Signals; Red Dots = Non-Adaptive Signals

Oakland County has over 1500 traffic signals and is home to one of the largest adaptively controlled signal systems in America.

655 = Adaptive Traffic Signals
430 = Non-Adaptive Road Commission signals
265 = Non-Adaptive MDOT signals
175 = Non-Adaptive City signals

1525 = Total Signals

In comparison, there are 20 roundabouts in the county.

Zwolle

120 000 inhabitants
63 traffic signal controlled intersections, plus several bicycle / pedestrian crossings

Interestingly, there is a large neighborhood (Stadshagen, 20 000 inhabitants) with no traffic signals at all. The city center does not have any traffic signals either, but is mostly car-free and does not attract much traffic other than shoppers going to the parking garages on the edges.

Around ~1,200 intersections with traffic lights in the Cape Town metropolitan area (2,454 km², population 3,497,097 as of 2007).

These figures do include some of the more outlying areas.

i think i've heard about this, wasn't this an experiment to see what would happen without traffic lights and signs, and it turned out to work brilliantly (people driving much more cautiously politely etc.)?

or is this something that' fairly normal in the netherlands?

You mean the "shared space" ideology. The traffic engineering world is divided about this, some welcome it as traffic calming, others don't like it. It also doesn't work in heavily trafficked areas.

The Stadshagen urban development does not have shared space, instead the neighborhood is split in two parts with all intersections either uncontrolled or with roundabouts. You can't get from one side to the other side to the neighborhood other than by bicycle, bus or via a long detour across the bypass road. Opinions about this remain heavily divided too.

Can't find any numbers on cities in Belgium.
I found these though:

Flanders: 6.251.983 inhabitants,13.521 km², 1686 traffic light controlled intersections.
Wallonia: 3.456.775 inhabitants,16.844 km², 620 traffic light controlled intersections.
Brussels: 1.145.292 inhabitants, 161 km², 413 traffic light controlled intersections

We are doing ok if I look to the other numbers...

I don't really know how many traffic lights there are in Helsingborg, Sweden.
But I do know, that it is popular in Helsingborg to change the traffic lights in junction to roundabout. All the major traffic light junction has been transformed to roundabout.

For what purpose, I don't know.
