For decades, transportation policies focused on the efficient movement of vehicles and goods without always considering the underlying economic, environmental, and social impacts. Just as important is the accessibility the system provides for people; whether it’s getting to a job, or school, shopping, entertainment, or recreation. At the same time, transportation remains the largest contributor of greenhouse gas emissions and while automobiles have become more efficient over time, these improvements are offset by an overall increase in driving, trucking, and air travel. Proposals for reducing emissions include electrification, increased investment in active and shared transportation, and improved land use.
