How can I achieve this effect?

Hi graphic designers,

I'm trying to fill my portfolio with some new posters. I really want this effect seen in the background of this photo, behind the cars, that blurry/motion thing. How can I get something like that? Does it have a specific name?
Thank you!

It’s called motion blur. Filter- blur - motion blur - zoom effect
