How do I turn off travel suggestions & event alerts?

Hi. My iPhone 7 Plus continues to give me travel times and suggested routes to recurring events on my calendar. It will also give me alerts for when it's time to leave, even when I don't have an address listed, or have an alert set. How do I change the settings - in Maps? Or elsewhere?

It also will not let me reset my home address, as I've just moved, and it keeps suggesting travel routes & times to my old home. Help!

Please let me know if you'd like more details in how to resolve these issues.

Thanks for the help in advance!
