The project investigates potential uses of appropriate and cost-effective high-tech solutions in helping LICs to improve their knowledge of the location and condition of their rural road networks. This report covers satellite condition trials carried out in Ghana, Kenya, Zambia and Tanzania. Imagery was procured for all countries at very high resolution, along with SAR imagery and some lower resolution imagery to test the feasibility of reducing the cost. Training has been completed in all countries in GIS applications and image interpretation, in order to prepare the teams to assess road condition from the imagery.
Some conclusions and recommendations have been made, which focuses on maximising the strengths of the manual assessment system, whilst identifying the weaknesses. These lessons learned were used to develop the methodology to be included in the final guideline. The project will conduct a workshop at the T2 conference in Zambia during May 2017, where the potential for practically implementing the high-tech solutions identified, including the satellite imagery assessment, will be explored.
