VISIAM (Visual Street Index for Active Mobility): An AI-Based Tool for Assessing Bikeability and Walkability of Streets

This project proposes the Visual Street Index for Active Mobility (VISIAM)—an AI-driven framework that integrates computer vision, self-supervised deep learning, and human-perception data to systematically assess bikeability and walkability at the street segment level. Current tools for assessing bikeability and walkability are limited because they rely on subjective audits or basic metrics. VISIAM addresses this gap through a multi-stage framework: computer vision models extract and classify streetscape features from Google Street View imagery, human-perception evaluations from diverse stakeholder groups rate street imagery across multiple dimensions, and the AI-derived classifications and human ratings are integrated to produce a composite bikeability and walkability score for each street segment. The final output is a citywide, street-level index visualized through interactive maps and dashboards, enabling policymakers to identify gaps, prioritize investments, and explore how infrastructure improvements could improve street quality.
