Traffic congestion has a negative impact on the economy and the environment. Vehicles are the second largest source of greenhouse gas emissions and one of the two main contributors to ozone pollution, and growth in vehicles miles traveled (VMT) leads to increased emissions. The rise in VMT contributes to the worsening air quality problem. Therefore, the State of Colorado must develop methods to manage and reduce overall transportation demand on the transportation network, and to encourage a shift from polluting gasoline and diesel vehicles to zero emission vehicles (ZEV), such as electric vehicles (EV). Secondly, the State must provide incentives to convert trips made in internal combustion engine (ICE) vehicles into trips using ZEVs. Thirdly, the State must slow the growth in VMT by incentivizing pooled ridership in which more than one passenger shares a vehicle for a trip.
