3.7.4 Indirect costs
The road infrastructure is one of the most essential factors for the economics of a region.
Without a road network there is no, or limited transportation possible. In addition to the basic
necessity of life like the supply of food and medical care, trade is not possible. This could have
an enormous influence on the economics of that region.

For example: farmers have to throw away their harvests after a flood, even when the harvests
have not been destroyed. Industries have to close because they cannot transport their goods.
Therefore the availability of the road network is more important for the economics of the
region than just the maintenance costs.
These costs which are not always expressed in exact values are the indirect costs.
