Enhancing Accessibility of Rural Populations through Vehicle-based Services
CoRR(2024)
摘要
Improving access to essential public services like healthcare and education
is crucial for human development, particularly in rural Sub-Saharan Africa.
However, limited reliable transportation and sparse public facilities present
significant challenges. Mobile facilities like mobile clinics offer a
cost-effective solution to enhance spatial accessibility for the rural
population.Public authorities require detailed demand distribution data to
allocate resources efficiently and maximize the impact of mobile facilities.
This includes determining optimal vehicle service stop locations and estimating
operational costs. Our integrated approach utilizes GIS data and an
accessibility scaling factor to assess spatial accessibility for rural
populations. We tailor demand structures to account for remote and underserved
populations. To reduce average travel distances to 5 km, we apply a clustering
algorithm and optimize vehicle service stop locations. In a case study in rural
Ethiopia, focusing on four key public services, our analysis demonstrates that
mobile facilities can address 39-62% of unmet demand, even in areas with
widely dispersed populations. This approach aids decision-makers, including
fleet operators, policymakers, and public authorities in Sub-Saharan Africa,
during project evaluation and planning for mobile facilities. By enhancing
spatial accessibility and optimizing resource allocation, our methodology
contributes to the effective delivery of essential public services to
underserved populations.
