Let's not forget that they probably buy each traffic light (All three colors) for only QR500,000, and pay QR/50,000 per year for maintenance and bulb replacements.

We all know how this is done, it's done in steps.

1. Choose a roundabout, then start planting it with flowers, grass, and decorate it with those nice stones QR200,000 Only.

2. Then, install 8xlights systems and a controller, for a special price of QR4,000,000.

3. Then after a while, install cameras, only QR1,000,000.

4. The next year you can install the timers, only only QR500,000.

5.plant it again with flowers, grass, and decorate it with those nice stones QR200,000 Only.

6. Then decide to convert the R/A with traffic lights to a full traffic lights interchange: close the R/A for a month or three, or six, dig it up, throw all the existing hardware,and install the basic lights system. QR 3,000,000

6. Repeat steps 3 and 4.

Notice that the different places in Doha are in different stages.
