ROLLIN

Introduction to ROLLIN

ROLLIN is a data platform that provides verified, granular accessibility information for restaurants and bars across the United States. It addresses the challenge of inconsistent or incomplete accessibility disclosures by replacing binary 'yes/no' indicators with a transparent, quantitative 0–100 accessibility score. The platform serves individuals who rely on wheelchair-accessible infrastructure, as well as developers, designers, and organizations building inclusive digital experiences.

The service currently covers over 56,000 locations across six states: California, New York, Florida, Massachusetts, New Jersey, and Pennsylvania — spanning 22 distinct geographic regions. All data is grounded in multi-source verification, including on-site assessments, community feedback, and structured public records. ROLLIN operates as a free-to-use resource with no account required for basic map and search functionality.

Key Takeaways

• Quantitative accessibility scoring: Each location receives a 0–100 score based on six verified features — wheelchair entry, level entry, accessible restrooms, accessible parking, elevator availability, and wide aisles.
• Interactive, filterable map: Supports real-time filtering by specific accessibility features and minimum score thresholds; includes location-aware 'near me' search.
• Offline capability: Users can download regional datasets and access verified accessibility information without an internet connection.
• Developer-first infrastructure: Offers a free REST API with six endpoints, JSON responses, API key authentication, and Python SDK support.
• Community-informed data: Enables users to submit feedback and corrections, contributing to continuous score refinement and data accuracy.
• Transparent methodology: Scoring system is publicly documented and evolves through multi-source verification and community feedback loops.
• Coverage expansion: Currently live in 22 regions across six states, with Illinois, Minnesota, and Colorado scheduled for upcoming rollout.

How ROLLIN Works

ROLLIN aggregates and validates accessibility data using a combination of field verification, public records, business submissions, and user-reported observations. Each location is evaluated against six standardized physical accessibility criteria, and scores are calculated using a weighted algorithm that reflects functional usability—not just feature presence. The resulting 0–100 score is broken down per feature to show where accommodations succeed or fall short.

Users interact with the platform via a web-based interactive map or direct API integration. The map interface supports geolocation, dynamic filtering (e.g., 'show only locations with accessible restrooms and a score ≥80'), and one-tap navigation. Developers consume the same underlying dataset through RESTful endpoints, enabling integration into third-party reservation platforms, travel apps, or accessibility-focused assistants.

All user feedback—including confirmations or corrections—is routed into a review pipeline that informs periodic score recalculations. This creates a closed-loop verification system where community input directly improves data quality over time.

Core Benefits and Applications

Individuals benefit from reliable pre-visit planning: knowing in advance whether a restaurant offers step-free entry, accessible restrooms, or sufficient maneuvering space eliminates uncertainty and reduces logistical burden. For developers, ROLLIN serves as a production-ready source of structured accessibility metadata—enabling features like accessible route planning, inclusive search ranking, or compliance dashboards.

Organizations in hospitality, urban planning, or disability advocacy use ROLLIN’s dataset for benchmarking, policy development, and accessibility gap analysis. Its offline mode supports field workers conducting site audits, while its API supports scalable integration into existing consumer applications—such as reservation services, mapping tools, or voice-assisted navigation systems.
