A new approach to the funding, management, and operation of transporta
tion infrastructure is emerging, ''Privatization'' refers to several d
ifferent ways in which private sector firms, usually under some form o
f government supervision, assume significant responsibility for these
major systems. Although the traditional U.S. model of user taxes, trus
t funds, centralized resource allocation, and government ownership and
operation has produced reasonably good transportation infrastructure,
this approach carries with it incentives for suboptimal performance-s
uch as allocating resources on political rather than economic-value gr
ounds, encouraging congestion at peak hours, and skimping on maintenan
ce. The privatization techniques offer the potential of institutionali
zing a better set of incentives for cost-effective performance. This a
rticle explores the use of (1) contract management and operation, (2)
long-term franchises and concessions, and (3) divestiture as privatiza
tion modes that can be applied to highways and airports.
