Smart transportation economic stimulation: infrastructure investments that support economic development
This report discusses factors to consider when evaluating transportation economic stimulation strategies. Transportation investments can have large long-term economic, social and environmental impacts. Expanding urban highways tends to stimulate motor vehicle travel and sprawl, exacerbating future transport problems and threatening future economic productivity. Improving alternative modes (walking and cycling conditions, and
public transit service) tends to reduce total motor vehicle traffic and associated costs, providing additional long-term economic savings and benefits. Increasing transport system efficiency tends to create far more jobs than those created directly by infrastructure investments. Domestic automobile industry subsidies are ineffective at stimulating employment or economic development. Public policies intended to support
domestic automobile sales could be economically harmful in the long run if they increase future energy consumption and transportation system inefficiency.
