One way policy can encourage it is through the expansion of broadband internet access as a critical element of transportation infrastructure.
"Whereas the infrastructure for cars, buses and trains consists of roads and rails, the infrastructure required for telecommuting is broadband. Fortunately for the framers of the new transportation package, the stimulus legislation already provides significant funding - over $7 billion - to expand access to broadband. The transportation legislation should provide more. It should also expressly encourage the use of that broadband to telecommute."
