The use of appropriate high-tech solutions for road network and condition analysis, with a Focus on Satellite Imagery, Tanzania Report

Abstract

This report assesses the suitability of some technologies used in the high-tech solutions project to the road network in Tanzania. An extension was granted to test the methodology in an appropriate environment and in a roll-out scenario for a specific situation, as defined by the Roads Fund Board (RFB). A guideline has been completed and is available on the ReCAP website, which outlines potential high-tech solutions, and gives specific guidance on the inventory and condition assessment methodology from satellite imagery and the situations in which it should and should not be used. Guidance is also provided on how different technologies can work together. The satellite imagery has been procured, the ground truthing was completed using existing data and videos for the two sites and the training was undertaken from 9 to 13 April 2018, in Dar es Salaam. The RFB invited the participants to the training and it was held at Ardhi University. This report assesses the relevance of the methodology to Tanzania and is based on the results of the training, training exercises, feedback from workshops held at the training and formal course feedback. 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)
