Highway 1, Calgary to Salmon Arm: what was logged, and what wasn't
One observer and five passes in spring 2026, covering about 470 km of the Trans-Canada. This is a record of coverage. It is not a wildlife survey, a patrol record or a safety assessment.

2,264automatic track samples; 91% came from the 31 May pass

What's here
Network state along the road. Of the 12 offline samples, 6 are inside Yoho. One pass only, never retested.
Road surface: 2,141 phone-accelerometer scores, 75 at 50+ of 100, plus 1 logged damage point. Uncalibrated, so compare within a pass only.
34 field records with GPS and time, 20 of them inside national parks. Most carry a stop label.
10 roadside photos tagged by a vision model. Most tags are low or medium confidence and no botanist has checked them.
The gaps
Wildlife: a roadkill deer and a mule deer, both east of Banff. No transects were run, so an empty block doesn't mean no animals.
Season and hour: no highway pass after 14 Jun and none in winter. All records fall between 07:39 and 19:34, so nothing at night.
Repeat coverage: 27 of 48 blocks have a track from one pass only, and 7 have none. The 14 Jun pass logged stops but no track, so it doesn't retest the offline spots.
Reach: within 1.5 km of the highway only. Nothing here speaks to backcountry or to what happens away from the road.
