Americans are told that the most serious problem facing the nation’s transportation infrastructure is a lack of money. Perhaps people would be willing to pay more if they receive a money-back guarantee in return.

Today’s roadway funding depends primarily on motor-vehicle fuel taxes and state and local appropriations. But federal fuel tax revenues no longer keep pace with needs because of the self-serving assumption that it’s become politically impossible to “raise taxes.” Everyone wants better roads and bridges, but almost no one wants to pay for them.

All this makes finding adequate funding to rehabilitate the nation’s highway system, add new lanes and highway corridors a major challenge. Between 2005 and 2015, there were two five-year federal surface transportation reauthorization bills and 34 short-term funding extensions. To maintain the committed level of funding, the federal government was forced to raid the General Fund for an average of $10 billion per year to supplement the dwindling Highway Trust Fund

Even so, Congress struggled to find the revenues to support a long-term bill without increasing the fuel tax, which has remained at 18.4 cents per gallon for cars since 1991. Congressmen have moved in unison to avoid dealing with an increase in the federal fuel tax.

In real terms, fuel tax revenue is actually projected to decline as the nation’s motor vehicle fleet becomes more fuel efficient. It is safe to say that the fuel tax is like a marriage that dies long before divorce papers are filed.

At the same time, state and local government budgets are increasingly burdened with funding demands for education, fighting crime, better security against terrorist threats and a host of other deserving services. Roadway funding inevitability gets shortchanged which is relatively easy to do, since it takes a while for the impact to become apparent.

A new U.S. Department of Transportation “conditions and performance” report estimates that there is a $926 billion backlog of needed highway and transit infrastructure projects, and that many more billions more will be needed to keep up with demand over the next 20 years. The congressionally mandated biennial report identifies an $836 billion highway and bridge backlog.

The public can quibble about the size of these numbers, just as maritime historians do about the size of the iceberg that sank the Titanic. But their magnitude is so enormous that it scarcely matters whether the estimates are off by 5 or 10 percent. What matters is that the needs are enormous, and the longer you wait to address them, the worse they become.

Senate Democrats just unveiled a 10-year, $1 trillion infrastructure plan that includes $210 billion to repair “crumbling” roads and bridges, but they are vague about how to finance it other than through direct federal spending. During the campaign, President Trump also called for a $1 trillion infrastructure investment that proposed leveraging new revenues and using public-private partnerships to incentivize investment and spare taxpayers from bearing the burden.

At one end of the funding spectrum are people who think the public should pay for it via tolls. At the other end are those who argue that the benefits transportation infrastructure provides aren’t confined to users, so society as a whole should pay out of general tax revenues. Between these extremes lies a range of payment mechanisms.

But for a plan to be accepted by American motorists, it must be perceived to deliver superior travel service with appropriate regard for equity and environmental considerations. One thought is to pair any increase in taxes or user fees with a money-back performance guarantee so customers can rest assure that they will get guaranteed travel-time savings in return for paying for access to surface transportation such as highways. This gives the travelling public confidence that they are getting their money’s worth.

The rapid introduction of intelligent transportation technologies facilitates an efficient way to implement a money-back guarantee. The result would be a dramatically transformed approach to transportation infrastructure.
