Speed bumps are a type of traffic calming, but traffic calming can include a variety of other techniques that can have other benefits. For example, extending sidewalks in residential areas or adding protective bollards to bike lanes - both encourage drivers to slow down by reducing the size of the lane.

Mode filters are a great way to fix this problem. No one will use a private street as a through road if they can't get anywhere outside the neighborhood. Bonus points if you make it so emergency vehicles can get through them.

You’re being by downvoted but I’m not sure why (though I can guess). Anyway, you might be happy to know that speed bumps are what is referred to as a traffic calming device; it might seem like an odd new term but it is a normal term in traffic engineering.
