This paper focuses on the derivation of the criteria to decide (i) where, (ii) how, and (iii) by what amount, public funds should be allocated to investment in transportation infrastructure such as railways, new trunk lines, highways, expressways, ports, airports etc. The methodology adopted is that of an extended interregional input-output programming model. This approach solves concurrently the problem of the measurement of the social benefits of private and public sector production, and the problem of derivation of the public investment criteria themselves.
