I count 50 people. I estimage this bus is to scale. 50 people on a city bus of that size is a tad crowded, but I've easily been on buses of that size with 90 people.

I counted on my local bus, though that was 20 years ago, and they've redesigned the buses since. In those days there were 45 seats. I counted 50 people.

So basically every seat is sat in, and you have about 5 people standing. Not too bad. I've been in buses where every seat is taken, sometimes 2 people in a seat (usually a parent sitting, with child on lap). While the standing area is wall to wall packed.
