Benefits
- The ITS improvements would result in decreased vehicle pollutants and reduced fuel use in the Seattle area.
- Full deployment would result in a reduction for all emissions analyzed. Carbon monoxide and hydrocarbon emissions were reduced by approximately 16 percent and 17 percent, respectively, while nitrous oxides were reduced by more than 21 percent.
- Fuel use in the region was cut by more than 1 million gallons per day, a total reduction of more than 19 percent. This represents an average savings of more than 0.1 gallons per trip.
