Fictional journey network. Original fictional resource; not an official map or real dataset.
Resource description
Travel times and status: A–B: 4 minutes, open; B–D: 8 minutes, open; A–C: 4 minutes, open; C–D: 3 minutes, closed; B–C: 10 minutes, open. Travel is allowed in both directions on open links.
Use the resource carefully
State the unit and the part of the resource you used. A pattern in a fictional dataset is evidence for that exercise; it does not establish a fact about a real place.
Check whether an explanation is supported by the data or needs additional geographical knowledge. For statistical tasks, a calculated result does not establish causation or significance by itself.
