Rural Access Index (RAI) Measurement Tool: Proof of Concept
The RAI Tool enables calculation of the proportion of the rural population who live within 2 km of an all-season road for every country globally
Abstract
ReCAP engaged with Azavea to develop a software framework for the Rural Access Index (RAI) Measurement Tool that enables the calculation of the proportion of the rural population who live within 2 km of an all-season road for every country globally. The proof of concept application is complete and the results are available at rai.azavea.com. The tool calculates the RAI value for all countries using open datasets (OpenStreetMap, WorldPop (2019), GRUMP) and the methodology for measuring SDG 9.1.1 developed by the World Bank in 2016, and Supplemental Guidelines developed by TRL. For three trial countries, the tool displays the results of the open data approach, in addition to the results of an approach using data provided by road agencies in each country.
This work is part of the Applied Research on Rural Roads and Transport Services through Community Access Programmes in Africa and Asia (AFCAP2 and AsCAP)
