Even if we hit the most ambitious targets for changing our cars and trucks over to electric vehicles, we will fail to meaningfully reduce emissions from transportation without confronting this simple fact: new roads always produce new driving. This costly feedback loop referred to as “induced demand” is the invisible force short-circuiting the neverending attempts to eliminate congestion by building or expanding roads.

Transportation for America is partnering with RMI and the Natural Resources Defense Council to release a new calculator that shows how highway expansion repeatedly fails to reduce congestion and instead increases traffic and pollution. The SHIFT Calculator provides transparency about new traffic created by highway widening and expansion so transportation agencies can make smarter, more sustainable transportation investments.
