Good transport facilitation policies are policies which have a positive impact in the reduction of trade costs. There are two important assumptions in this, the first being that the problems to solve have been correctly identified, and the second, equally important, is that a noticeable progress can be measured. SSATP through its Regional Integration component has developed, and continues to refine and expand, a comprehensive toolbox of diagnosis and monitoring instruments grouped under the generic term of ‘transport observatories’. The SSATP transport observatory activities have the double objective of enhancing and strengthening the content of the toolbox, while providing technical assistance for its actual implementation and use in the policy dialogue in African corridors.
