Where could sharing the ride actually work?

Metro says geography helped shape its vanpool proposal. This map asks the same question with public data, one layer at a time.

527strong shared-flow signals

15,581workers in those flows

Start here

A line means at least 20 workers lived in the same Census tract, worked in the same Portland-region tract, and traveled at least 20 straight-line miles. It is a reason to investigate, not proof that 20 people share a schedule or want a van.

What this can and cannot establish

The map can show geographic concentration, distance, cross-jurisdiction travel, and proximity to scheduled routes. It cannot reveal individual workers, compatible shifts, willingness to participate, actual transit travel time, reliability, disability accommodation, or long-term group durability. Those require additional data and validation.
