ADA Service Area Generator
The Challenge: A Moving Target
ADA paratransit eligibility isn’t a map you draw once. Every time a fixed route changes, so does the service area around it, and for most agencies that means redrawing polygons by hand, occasionally, and hoping they’re still close enough to right between updates. When a route shifts and the map doesn’t, that’s not just a cartography problem. It’s a compliance one.
That’s where Spatialty can help. We’ve built and refined this exact process at the highest scales, and we can bring that same automation to your agency.
ADA Service Area Generator: Automated Compliance Mapping
The ADA Service Area Generator is an automation workflow built on the same Spatialty-designed FME engine behind our GTFS-To-GIS pipeline. It reads directly from your GTFS feed and generates complementary paratransit service area polygons per the corridor and end-of-line requirements in 49 CFR 37.131, the FTA’s ADA paratransit regulation. Feed in a route change, get back a compliant map. No manual redrawing, no stale polygons sitting in a folder from two service changes ago.
Downstream Intgrations
Utilizing the power of FME, ADA Service areas can be exported from your GIS to the destination system. We have successfully provided data to Trapeze, SpareLabs, GeoJSON, and ArcGIS Online.
Why Automate with Spatialty?
1. Stop Manually Drawing, Start Automating
Your service area should be exactly as current as your GTFS feed, not as current as the last time someone had a free afternoon. Automating this removes the lag between a route change and a compliant map.
2. Built on Regulatory Logic, Not a Generic Buffer
This isn’t a flat buffer dropped around a line. It’s built to reflect the actual corridor and end-of-line geometry defined in 49 CFR 37.131, refined over a decade of production transit GIS work.
3. A Foundation, Not a One-Off
Once the engine is in place, the same GTFS-driven approach extends naturally: rider-facing eligibility lookups, board reporting exhibits, and FTA compliance documentation, all generated from the same trusted source.
The Spatialty Advantage
We don’t just hand you a script. We bring the expertise to fit it to your agency’s existing systems and data, tested against transit systems of very different scale and structure to confirm it holds up beyond one agency’s particular quirks.
