Adequate, designated pedestrian areas in parking decks are pretty rare. When crosswalks or paths are provided, they sometimes look as if the designer had only a vague idea what they’re used for.
An example:
One entrance to this Buckhead shopping center has good pedestrian access. Unfortunately it’s neither of the two most likely to be used by people who walk there. Those two entrances lead through the parking deck and feature a crosswalk that runs into columns twice, then vanishes just when it reaches two opposing lanes of traffic. Having it continue toward the store, however, would have required eliminating a few parking spaces close to the door. It’s probably not easy to get something like that past developers who expect that most people will drive to their project. But even people who do drive there have to walk to make it to the stores.
Near the truncated crosswalk is what appears to be a sidewalk leading to Target’s entrance. It’s in fact just a curb barely wide enough for one person. But even that single person has to step off and out into the the traffic to edge around more columns.
All this has to be done while watching out for cars driven by people talking on the phone and trying to swoop into the nearest vacant parking space. If that’s not enough of an adventure, there’s always doing it again on the way out to look forward to.

I’m in awe of the Target/Kroger (et al) parking lot. It a non-obvious adventure by car or foot.
You mean the one on Edgewood? I’ve only been there a couple of times, walking from Inman Park Station. The north edge of the lot has a crosswalk that not only stops before it reaches the sidewalk, it’s placed in such a way that you’d have to crawl under parked cars and leap over a planter to use it.
