The problem
Currently, the main highways leading to Liberia and Mozambique are in poor conditions, causing local small business people and severe transportation and mobility safety problems. In particular, in Liberia about 50% of the major highways linking the capital city Monrovia to the rest of the country is in very poor condition, 15% in fair condition, and 35% in good condition.
It is estimated that in 10 years if no development and maintenance plan is designed, over 50 percent of the roads in the country would be in poor condition. In Mozambique the situation is very similar: There are 31,083 km, of which 7,365 km are paved and 23,718 km are unpaved.
Our approach
The objective of the consulting service was to develop a simplified methodology for road infrastructures’ safety assessment based on the automated analysis of video images. The simplified methodology was tested and validated through a pilot road safety assessment of highways in Mozambique and Liberia.
Our approach was to:
- Establish a methodology for simplified road infrastructure safety assessment based on the analysis of the contribution of road attributes on risk of road traffic crashes.
- Establish the standard of video filming for the analysis of road safety.
- Develop a simplified road risk assessment software using automated image analysis and coding tool based on the methodology developed.
- Conduct a pilot assessment of the national highway subsection in Mozambique and Liberia and provide the results of the road safety assessment.
