Comparable night freight on community-facing roads
Average classified truck passings per valid directional heading-night, so roads with different sensor counts can be compared more fairly.
Monthly night-freight trend — indexed for fair corridor comparison
Each eligible corridor starts at 100 in its first complete month. Low-volume baselines are excluded to prevent small absolute changes from appearing as exaggerated percentage movements.
