Your ADA infrastructure has
no digital record.
Most transit agencies cannot tell you how many stops they have, what condition they are in, or what it will cost to bring them into compliance. AccessTwin changes that.
ADA compliance is a liability crisis hiding in plain sight
No Baseline Inventory
Agencies operate thousands of transit stops with no structured data on physical condition, ADA features, or compliance status. You cannot fix what you have not measured.
Unfunded Mandates
Federal ADA requirements do not come with federal funding. Agencies must find capital within existing budgets while facing rising material and labor costs every year.
Litigation Exposure
ADA lawsuits against transit agencies have resulted in settlements exceeding $100M. Without documented compliance programs, agencies have no defensible position.
One system for your entire ADA program
AccessTwin™ manages every workstream of ADA infrastructure compliance -- from the first field audit to the final construction closeout -- in a single, agency-owned platform.
7-Step Field Audit
Structured inspection covering Parts A through G: location verification, surface conditions, landing geometry, tactile warnings, signage, amenities, and photo documentation. 80+ data points per stop.
Priority Scoring Engine
Automated scoring weights equity (40%), condition (30%), ridership (20%), and safety (10%) to rank every stop in your network. Data-driven capital allocation, not guesswork.
Design Through Construction
From Type A tactile pad retrofits to Type F full reconstruction, AccessTwin™ manages design packages, PE review queues, construction records, QA/QC checklists, and closeout documentation.
Five workstreams. One platform.
AccessTwin™ covers the entire ADA compliance lifecycle, from initial inventory through long-term condition monitoring.
Field Audit
SOP-F compliant field audit protocol on offline-capable tablets. Photo geotag, NDT integration, electronic signature.
Priority & Analysis
ADA deficiency scoring combined with PASER surface rating, slope measurement, safety, and boarding-flow analysis.
Design Production
Standard Details-driven design packages keyed to jurisdictional standard variations. PE review workflows built in.
Construction Oversight
Work order issuance, field QA, closeout documentation—all on the same stop record.
Program Management
