“I never realized sidewalks were a big deal”: A Case Study of a Community-Driven Sidewalk Audit Using Project Sidewalk

Bibliographic Information

• Subject Areas: Civic Technology, Accessibility Studies, Community Science
• Keywords: Accessibility, Civic Technology, Community Science, Service Learning, Crowdsourcing

Research Background and Problem

• Identified Issues or Challenges: Despite regulations in many countries supporting accessible sidewalk infrastructure, urban sidewalks remain unsafe or inconvenient for individuals with disabilities. Key challenges include insufficient government funding, lack of political will, weak community awareness, and limited knowledge among municipal staff. Additionally, the lack of standardized sidewalk data collection results in insufficient data, restricting research and planning for accessibility issues.
• Significance: Accessible infrastructure affects not only the daily mobility and social participation of individuals with disabilities but also impacts public mental health and community equity. Addressing sidewalk accessibility issues is crucial for achieving inclusive cities and has profound implications for advocating social equity.
• Research Motivation and Related Work:
  • Traditional sidewalk audit methods are time-consuming and expensive.
  • Emerging platforms (e.g., Project Sidewalk) offer low-cost methods for data collection through crowdsourcing.
  • Few studies have explored how these tools can support community accessibility advocacy and related efforts.

Solution

• Proposed Solution: This study investigates how communities can utilize an open-source crowdsourcing platform—Project Sidewalk—to assess sidewalk accessibility. Through an 18-month case study, the research analyzes the tool's potential in education, community advocacy, and behavioral change.
• Innovations:
  • Utilizing fully online tools to collect, analyze, and advocate for urban accessibility data.
  • Integrating community science and service learning models to enhance social participation.
  • Developing interactive analysis tools (e.g., LabelMap and Gallery) to visualize data in real-time for decision-making support.
  • Introducing community-oriented gamification features (e.g., leaderboards, personal dashboards) to sustain user engagement.
• Implementation Steps:
  1. Initiation Phase: Guiding the community to understand the tool through interaction with the research team.
  2. Data Collection: Conducting mapathon events with training sessions, using Google Street View to remotely label sidewalk issues.
  3. Data Analysis: Collaborating with the community and research team to interpret data using intuitive analysis tools.
  4. Policy Advocacy: Scouts presenting data and recommendations to municipal committees.

Research Outcomes

• Specific Results:
  • The application of Project Sidewalk in Oradell, New Jersey, collected 12,191 labeled tags, covering 35.9 miles of streets, with 93.1% of the labels verified.
  • Data revealed that sidewalk issues were primarily categorized as surface problems (32.4%) and missing sidewalk areas, with missing curb ramps identified as the most critical issue.
  • Scouts (Boy Scout members) completed the full scientific inquiry process and presented policy recommendations to the municipal committee.
• Advantages:
  • The tool is efficient, requiring no in-person time, thereby expanding the scope of data collection.
  • It raises community awareness of accessibility issues and fosters behavioral change.
  • It inspires young participants' sense of social responsibility and interest in scientific learning.
  • Successfully combines scientific research with community engagement, enhancing actionability.
• Experimental or Evaluation Results:
  • Interviews with participants revealed significant changes in attitudes and behaviors, such as a renewed understanding of accessibility issues and increased confidence in advocacy within the community.
  • Gamification mechanisms helped sustain user interest and continuous participation.
• Limitations and Future Directions:
  • Outdated GSV images may affect data accuracy.
  • The tool lacks accessibility for users relying on alternative input devices and visually impaired users.
  • The project's complexity and reliance on long-term collaboration make replication in other communities challenging.

Discussion and Recommendations

1. Tension Between Community Science and Learning Goals: Methods are needed to balance education and data quality improvement, such as enhancing participants' roles in project decision-making.
2. Potential and Limitations of Policy Advocacy: Community science projects should enhance their societal impact through long-term planning and policy influence.
3. Future Directions:
   • Customizing tool design to improve accessibility.
   • Introducing similar projects to low-income communities.
   • Further developing evaluation metrics to capture participants' learning outcomes and social impact.

Conclusion

The project highlights the potential of using civic technology tools to address accessibility issues and how these tools can serve as catalysts for education and advocacy. While policy changes may take time, such tools help drive cultural awareness shifts and community action, contributing to the creation of more inclusive urban environments.
