Is there a service for developing a city model?

Question

3D

I have a startup idea.
Various installations in the city. There is no such thing yet.
I need a service (if there is one at all) to develop a prototype city.
It is important that I can add various details there, for example, a speed bump, etc.
Is there such a service or program?
Thanks to
