Nevertheless, additional efforts are required, particularly concerning the collation/analysis of spatial data (in Spatial Data Infrastructures), the strengthening of national capacities, the identification of network bottlenecks and missing links4', as well as assessments of the criticality, sensitivity and resilience of indispensable components of the transport system (e.g. bridges and tunnels), and the sharing of experiences and 'best practices'(e.g. As shown by the distribution of LPI (Figure 3.14), certain improvements are necessary in many regions. International agreements and cooperation are required together with the adoption of widely accepted/trusted uniform standards, in order to promptly identify goods and facilitate faster border and customs clearing.
