[Attack on Titan] Titans are invading my town, how do I survive this?

Scenario 1: I'm in the AoT world and so live in one of their cities. The wall just got busted the fuck down and Titans are pouring in and are eating people. Where do I run, what do I avoid, how long have I got before I'm ripped in half and put in a titan-sized taco?

Scenario 2: I'm in the real world, and Titans just appear from no-where, once the military shows up they'll be dealt with but how do I survive waiting for them? Do I hide inside, upstairs, downstairs?

I round 1, follow your per-prepared evacuation plan. Since the Fall of Wall Maria, we've come to take this threat a lot more seriously, and implemented numerous civil defense measures. Follow those and you should be *just fine*.

For Round 2, enclose spaces are your best bet, unless you happen to have a helicopter in your back yard. Once the titans detect you, your fucked, so you need to stay out of sight. Fleeing in a vehlice comes to mind, but unless you live is a very small town, the roads will quickly become cloged and attract a large number of titans. A sub-basement is probably your best bet. 

Don't forget to bring a radio, some food and water, and a bucket, as it may be some time before the military shows up, and a titan might collapse the building on you. 

Modern personal firearms are largely useless against this type of threat, so hiding is your best bet. Let the trained professionals with heavy weapons deal with this.
