143. In contrast to some social infrastructure that may be built by PPPs, for instance hospitals and schools that may be considered a stand-alone asset, transportation and logistics infrastructure is more properly seen as a component of an overall transportation system. Therefore, they should be planned to integrate with other aspects of the national transportation system. For example, a road or port PPP built to accommodate a certain volume of traffic will never see that volume if there are bottlenecks and lower levels of capacity in other parts of the system that feed into the new PPP. This will be especially salient if the developer is expected to face traffic risk. The lack of an overall integrated national transportation plan or strategy will be problematic at best for transportation and logistics PPPs and may be fatal.
