| Topic | Existing Data | Major Gaps in Existing Data |
|---|---|---|
| Transportation expenditures | Total transportation expenditures by households, businesses, and government | Business investments and expenditures by mode of transportation |
| Transportation costs | Gasoline and diesel prices; costs of automobile ownership; air carrier costs for selected categories; carrier price indices; cost to maintain highway and waterway condition | Trucking costs by type of cost; rail costs based on actual operating expenses rather than regulatory formula; comprehensive costs for bus, general aviation, pipeline; cargo damage and loss |
| Transportation’s contribution to the economy | Transportation as a share of Gross Domestic Product; transportation embedded in other industries (the Transportation Satellite Account); transportation employment | Transportation as a share of state and metropolitan domestic product; economic activity enabled by transportation; value of transportation infrastructure |
| Safety | Transportation fatalities and injuries by cause for all modes; safety incidents involving hazardous materials; precursor events (close calls) for aviation, selected railroads and transit, and off-shore oil extraction and transport | Exposure by type of safety risk; precursor events (close calls) for most surface transportation; disabilities and medical costs related to transportation injuries |
| Energy consumption, green house gasses, air quality | Air quality by type of pollutant and air shed, relationship of vehicle emissions to type of vehicle and vehicle speed | In-use fuel economy, amount of vehicle travel by type of vehicle and vehicle speed in each air shed |
| Noise, water quality, habitat dislocation | Noise footprints around airports, environmental disruptions related to individual transportation projects | National and regional inventories of noise exposure from all modes, natural habitat disruption |
| Community effects | Proximity of population to transportation facilities; community disruption for individual projects | Neighborhood access to transportation services; transportation barriers to employment for disadvantaged areas; national and regional inventories of human habitat disruption |
