(Herzog 2001). It is necessary to identify appropriate environmental policies to mitigate transport and reduce its impact on the environment and include fuel and vehicle technology, transport management, research and infrastructure planning. Transportation departments will need to comply with specific policies to improve air, water and land quality to ensure that negative impacts on the transportation system are minimized. Clean energy policies must continue to be enforced to ensure the transportation system is not negatively impacted. Policies that would enable energy savings without impacting transportation improvements should be reviewed. Policies to control transport emissions that contribute to the greenhouse effect must be designed to ensure that the impacts of the transport system minimize negative effects on the environment. But these strategies can only work if state and federal laws implement these requirements. If the Department of Transportation does not comply, it should be subject to sanctions by the
