Improving the Efficiency of the U.S. Highway System Clifford Winston The Brookings Institution
Overview • Summary comments on roads • Raising revenue efficiently • Reducing costs efficiently • Spurring technical innovation
Highway Performance:Delays Average Annual Traffic Delay in Major Metropolitan Areas, 1982-2001
Highway Performance: Finances • The road system is always “balanced” but that is misleading • Revenue sources (the fuel tax) are volatile • Costs can be reduced by deferring maintenance and expansion • Innovation is rarely considered
Revenues: Efficient Pricing • Fuel tax is largely unrelated to motorists’ contributions to delay—doesn’t vary by time of day or location • Efficient tolls (road pricing): mitigate delays raise revenues efficiently (self financing) improve land use (other effects) • Redistributive effects exaggerated
Efficient pricing (continued) • Fuel tax provides wrong incentives for trucks to reduce weight per axle—the primary source of pavement damage • An axle-weight tax should be used to reduce maintenance costs • Generally, the fuel tax is an inefficient tax (emission, safety)
Reducing Costs: X-Inefficiency • Eliminate Davis Bacon (reduce labor costs) • Optimize capital/maintenance cost tradeoff with thicker pavement • Make contracting more flexible • Improve oversight to reduce cost overruns
Reducing Costs: Improve Allocation of Funds • Allocate highway expenditures to reduce total highway costs, accounting for users’ cost of congestion • $1 of spending reduces users’ congestion costs 11 cents; under optimal allocation $1 reduces costs 25 cents • Eliminate demonstration projects • Use prices as efficient signals of investment—cannot build our way out of congestion
Innovation: Motivation of Privatization • Vast pricing and investment inefficiencies in highway • Efficient pricing and investment would produce billions of dollars in welfare gains • Objectives of privatization: Reduce costs Make suppliers more responsive to users More rapid introduction of innovations
Developing Evidence to Make the Case for Privatization • The experience with deregulating intercity transportation in the United States • Foreign experience with privatization: private road builders • Experiments in the US to show competition can develop
