In 1955, the great radio show Suspense did a masterful job of adapting the story with a very chilling ending. You can hear it for yourself at archive.org here.
In 1984 the radio show Bradbury 13 adapted the story as "The Ravine" but used the version found in Dandelion Wine; you can hear it at Youtube here. A television version debuted on The Ray Bradbury Theater in 1992 as "The Lonely One" but I'm not sure the story works well on television; the bulk of the story goes on inside the mind of the protagonist as all her fears are intensified; the objective lens of a camera can't accurately depict what's going through her mind. A comic book version would be great, but there hasn't been one yet.
More macabre Bradbury tomorrow!
