Research Background and Problem

• Problem and Challenges:
  • Approximately 3.6 million Americans annually forgo medical services due to a lack of non-emergency medical transportation, disproportionately affecting low-income individuals, minorities, the elderly, and those with chronic illnesses or disabilities.
  • Transportation barriers lead to missed medical appointments, reduced use of preventive healthcare services, and increased reliance on emergency care, ultimately impacting health outcomes.
  • Commercial ridesharing services (e.g., Uber) face issues such as lack of trust in technology, digital literacy requirements, and insufficient service in low-resource areas.
• Significance: Providing equitable and reliable healthcare transportation solutions is critical to reducing health disparities.
• Research Motivation:
  • Existing technologies fail to fully address the needs of low-resource populations, necessitating alternative solutions.
  • The non-monetary transactions facilitated by timebanks may offer a novel approach to healthcare transportation, fostering community relationships and trust.
• Related Work:
  • Timebanks have been proposed as tools to promote trust and reciprocity mechanisms, but challenges remain in resource management and balancing service exchanges.

Solution

• Research Methods:
  • Conducted research in collaboration with a local timebank and a Federally Qualified Health Center (FQHC). Data sources included participant activity kits, online workshops, and demographic surveys.
  • Using a community-driven participatory approach, the study explored perceptions of trust and reciprocity among drivers and passengers in low-resource areas regarding ridesharing.
• Research Questions:
  1. How can ridesharing systems be designed to foster trust between drivers and passengers in the context of timebanks?
  2. How can ridesharing systems be designed to promote reciprocity between drivers and passengers in the context of timebanks?
  3. What roles might intermediaries play in fostering trust and reciprocity in ridesharing systems?
• Innovations:
  • Combining timebanks with healthcare transportation to address issues of trust and reciprocity.
  • Shifting system design focus from short-term transactions to long-term relationship building.
• Implementation Steps and Techniques:
  • Designed an activity kit to collect participants' opinions on ridesharing based on role-playing scenarios.
  • Conducted online workshops to discuss participants' needs regarding trust, reciprocity, and intermediary roles.
  • Analyzed data from activity kits and workshops to derive design implications.

Research Findings

• Specific Results:
  • Identified key factors influencing trust and reciprocity in ridesharing, including safety, reliability, cost-sharing, and long-term interpersonal relationships.
  • Timebanks, due to their closed network structure, are better suited for building trust; non-timebank intermediaries require certification and monitoring mechanisms to compensate for trust deficits.
• Advantages:
  • Compared to commercial platforms (e.g., Uber, Lyft), timebanks more effectively foster trust through community activities and long-term member interactions.
  • Extending reciprocity to include resource sharing and community support goes beyond the boundaries of traditional monetary transactions.
• Experimental and Evaluation Results:
  • Online workshops revealed that participants preferred selecting drivers and passengers based on timebank transaction histories.
  • Timebanks can support long-term relationship building through community events and features like "member badges" that demonstrate trustworthiness.
• Limitations and Future Directions:
  • The study was conducted only in the Detroit area, which may limit the generalizability of the findings.
  • The use of background checks remains controversial and requires further research to understand its role in trust-building.
  • The feasibility of implementing the design recommendations in actual intermediary organizations (e.g., timebanks and FQHCs) should be tested.

Design Recommendations

Promoting Trust

• Enhance the visibility of timebank members' transaction histories (e.g., "years of membership," "number of interactions," "record of past activities").
• Add certification features, such as driver qualifications or organization-approved badges (e.g., vehicle inspections, proof of insurance, and driver’s licenses).
• Provide video or phone interaction options for initial trust-building.

Managing Reciprocity

• Support light reciprocity, such as allowing participants to negotiate small fuel reimbursements.
• Offer inventory management features, such as borrowing car seats or sanitization equipment (for specific situations requiring additional resources).
• Encourage the system to enable participants to explore new forms of reciprocal exchanges (e.g., yard maintenance, tutoring).

Expanding the Role of Intermediaries

• Develop technologies to support pre-negotiation and alignment of transaction rules (e.g., indicating expectations for additional costs when selecting drivers).
• Centralize resource allocation strategies, such as providing tool libraries or funding pools to cover unaccounted expenses.

By implementing the design recommendations from this study, future technological platforms can better optimize healthcare transportation services for low-resource populations while expanding the application scope and social impact of timebanks.
