Know the walk before your child takes it

SafeWalkr finds the safest routes to school for students. We track Street View at every point on the route to curate safer paths, on top of county-wide traffic and sidewalk data.

For two of every three homes,
the safest route is not the shortest

We routed all 9,731 homes in our 14 walk zones both ways: shortest, then safest.

Homes whose safest route differs, by school level 2,571 homes sampled, all 188 FCPS zones

Elementary 1,405 of 1,899 differ · 74%
Middle 318 of 350 differ · 91%
High 300 of 322 differ · 93%

The safest route cuts walking in the roadway of busy roads by 86%, and it typically adds 25 seconds to the walk. An app that only finds the shortest route cannot see the difference. Read the measurement.

How a street becomes a routing decision

Today's routes run on the county inventory. The imagery verdicts join the engine zone by zone.

  1. Capture

    A panorama at every junction of the pedestrian network.

  2. Classify

    A vision model returns sidewalk or none, road type, canopy, and a risk score.

  3. Attribute

    The verdict is written onto that block's edge, beside the county sidewalk and traffic data.

  4. Route

    Cost rises with traffic and falls with sidewalks. The shortest path and the safest path are no longer the same.

The SafeWalkr map application. A route runs from a home on Southampton Drive to Kings Park Elementary, teal along calm sidewalked streets and purple beside the busier road, with each crossing marked. The sidebar reads 0.92 miles, 23 minutes, three road crossings and the crossing guard at Clydesdale Road with duty hours, and the open map key explains every colour.
