Traffic Architect Troubleshooting Guides
Diagnose Traffic Architect unreachable routes, undo and refunds, or a version mismatch before retrying a road edit or resetting a junction.
Start with the symptom and the last change
If Steam refuses to start the Mac game, use missing-executable launch checks. If the map turns white or black while the UI remains, use graphics-crash settings and logs.
For an unreachable building or destination, start with No Route Available and separate physical connectivity from movement rules. To take back a mistaken purchase or understand the displayed return amount, use undo and refunds. For a district countdown or lower-pressure mode, use district overload and difficulty helpers. If a patch says your problem is fixed but it still happens, check which edition and version the advice applies to.
A refused physical edit belongs with road-editing conditions; a changed green duration or custom phase belongs with signal settings by trigger and version. Record that difference before resetting a junction.

- District overload & difficulty helpersRead the overload reason, inspect district routes and choose the available assistance.
- Mac missing game executableMatch the release-day Mac launch error, refresh Steam and verify the installed game.
- White map, black screen or graphics crashSeparate a GPU-process crash from congestion, test stated settings and gather the matching log.
