+- **BREAKING:** `stop_visits` duration fields renamed from `_time` to `_duration` suffix to distinguish from timestamp fields: `ramp_deployed_time` → `ramp_deployed_duration`, `kneel_deployed_time` → `kneel_deployed_duration`, `lift_deployed_time` → `lift_deployed_duration` ([#237](https://github.com/TIDES-transit/TIDES/issues/237))
