Immediate–not delayed–healing

The Editors

There’s a familiar sign that pops up, like dandelions, every spring and summer along hundreds of miles of United States highways: “Work area ahead. Expect delays.” For many, though, the sign’s message suggests more than just orange barrels and traffic jams. For example: 

• Major airlines serving London say passengers will face “severe delays and disruption” during the 2012 Summer Olympics, unless the British government takes “urgent action.”

• Last year the Board of Trade in Toronto, Canada, released a study that found traffic congestion—even without construction zones—cost the region $3.3 billion in lost productivity.
