Capitalism at Work on an Interstate Highway

Traffic speeds during the peak eastbound commute on the 66 Express Lanes Inside the Beltway have dropped to 35 mph. "Toll-tweaking" and changing the algorithm are achieving limited success on this dynamically-tolled stretch.

During commute hours, nine miles [png] of Interstate 66 in Northern Virginia, formerly known as the 66 Express Lanes Inside the Beltway, may operate like no other public roadway, let alone interstate, in the United States. During the morning restricted travel period from 5:30 a.m to 9:30 a.m., all (two to three) eastbound lanes are dynamically priced—there are no adjacent general purpose lanes for single-occupant vehicles (SOVs) to take to avoid paying a toll, which, on occasion, top $40.

The afternoon restricted travel period extends from 3 p.m. to 7 p.m. on all the westbound lanes. Once again, no "free lane" to choose if you lack a passenger.

The uncapped, dynamic tolling makes the roadway stand out as an example of how effective congestion or value pricing is at reducing congestion, encouraging modal alternatives, and funding public transit with toll revenues.

The operator of these time-restricted, high-occupancy toll (HOT) lanes, the Virginia Department of Transportation, is trying, perhaps paradoxically, to reduce the tolls and, at the same time, increase the speed, during the most congested part of the commute hour, from 8:15 a.m to 8:30 a.m, "when average speeds in April slowed below 35 mph," reports Max Smith for WTOP News on June 8. The roadway is unique for another reason: the low number of commute-hour SOVs.

About two-thirds of the vehicles on the road at that time are riding free — motorcycles, buses, and cars carrying at least two people with an E-ZPass Flex switched to HOV mode. Speeds in the morning remained slower than the same period a year earlier between 7:30 a.m. and 9:15 a.m.

While one way to deal with the slowdowns around 8:30 a.m. could be to raise tolls even higher as speeds significantly slow at that time, Virginia Transportation Secretary Shannon Valentine  hopes changes to the tolling algorithm, along with better communication to commuters, could provide a different path if drivers change how they commute to either carpool, take the bus or go in at a different time.

It is somewhat ironic that an interstate highway that takes workers to the seat of American government would be one of the best examples in the country of applying market forces to auto travel.

“Because this is a true dynamic tolling system where people are making decisions in the moment based on the cost, it is true capitalism. … If we mandate certain limits, we can’t adjust it,” Valentine said.

The Roadway Expansion Paradox

Motorists want expensive roadway expansions provided that somebody else foots the bill, but when required to pay directly through tolls, the need for more capacity often disappears. What should planners do?
