1) General Performance
Efficiency measures relate resource inputs to intermediate
or final outputs (see below). In contrast, in this first section, simple performance indicators are
plotted that illustrate the state of transport infrastructure supply or demand, without putting these in
relation to the inputs.
1a) Transport Infrastructure
1b) Transport Flows
2) Efficiency and Productivity
Efficiency indicators relate resource inputs to intermediate or final outputs.
2a) Technical Efficiency (Technical Productivity)
Technical efficiency refers to the physical relation between resources
and transport outcomes.
2b) Productive Efficiency (Economic Productivity)
Technical efficiency cannot directly
compare alternative interventions, where one intervention
produces the same (or better) transport outcomes with
less (or more) of one resource and more of another. Productive
efficiency refers to the maximization of transport outcome
for a given cost, or the minimisation of cost for a given
outcome. Productive efficiency enables assessment of the
relative value for money of interventions with directly
comparable outcomes. To-date, economic productivity measures
unfortunately only exist for few ESCAP member countries
(see, in particular, the 60-Industry
Database of the Groningen Growth and Development Centre).
2c) Allocative efficiency
Productive efficiency cannot address the impact of reallocating
resources at a broader level, e.g., from urban to rural
areas, because the transport outcomes are incommensurate.
The concept of allocative efficiency also takes account
of how the transport outcomes are distributed among beneficiaries.
Allocative efficiecny is achieved when resources are allocated
so as to maximise the welfare of the "community".
