I've heard a lot about how a Rogue's specialty is disarming traps, even going as far as online DMs suggesting Rogues always use the Investigation action to watch for those traps. And while I do not disagree that their expertise in Thieves' Tools would make them the most effective measure against them, I am wondering if a Barbarian's Danger Sense would not also be useful in this endeavour.
The Barbarian's Danger Sense feature description states, in part:
At 2nd level, you gain an uncanny sense of when things nearby aren’t
as they should be, giving you an edge when you dodge away from danger.
The way I understand this sentence is something like a short-distance passive Investigation or Insight check, where "Something just doesn't feel right" and should prompt the Barbarian to naturally stop and do an Investigation check to find the abnormality… It might be something like subconsciously noticing the series of holes lining the doorway, or obscurely feeling the eyes of the assailants in the trees ready to pounce. Even without amplifying this with the Dungeon Delver feat's advantage to checks, it seems quite a complimentary feature to combine with the rogue's skills.
For example:
The party walks down the empty hallway, devoid of the few guards they came to expect. Brutus the Barbarian acts as vanguard while they press forward, stopping abruptly as they reach an open doorway on the other side. "Something's wrong," he says, prompting the rogue to investigate, discovering that neither shadow nor light enters the room. Though the floor near the statue on the right shows signs of being moved rather recently.
Am I correct in my interpretation?

Danger Sense just grants advantage on Dex saves
You're missing the second half of the description of the Danger Sense feature:
Walking down a corridor is not dodging away from danger. It's just walking.
That line you quoted is just the build-up to the mechanical explanation of the feature.
