Thursday, April 9, 2015
Topic | Coverage of Existing Data | Major Gaps in Existing Data |
---|---|---|
Intercity and International Travel | Volumes and origin-destination patterns of commercial aviation passengers; Amtrak ridership; volumes of people and number of motor vehicles at border crossings | Origins, destinations, and volumes of travelers by personal vehicles, buses, and general aviation; amount of travel by demographic characteristics of travelers; travel by general aviation; domestic surface travel of international visitors |
Local travel | National volumes and demographic patterns of travelers by type of place; transit ridership by property; detailed origin-destination patterns of journeys to work and demographic characteristics of commuters; geographic and demographic patterns of all resident travelers in metro areas that have conducted local surveys | Travel by non-motorized modes; local travel other than commuting in metro areas that have not conducted local surveys; ridership on transportation services provided by social service and non-profit organizations |
International freight movement | Volumes and value of freight at international gateways; value of trade by country | Domestic transportation of international trade, including domestic leg of imports, exports, and transshipments through the United States |
Intercity freight movement | Region-to-region flows by commodity and mode | Relationships between industry supply chains and region-to-region commodity flows |
Local freight movement | Freight movement only in the rare cases where state and metro area surveys are conducted | County-to-county and intra-county flows of freight; through movement of freight |
Vehicle movement | Number of vehicles on highway segments; number of aircraft by airport; number of car-loadings by rail segment; number of vessels by port and waterway | Inconsistent differentiation among types of highway vehicles (car, bus, truck); pipeline volumes by segment |
Extent of and geographic access to the transportation system | Multiple versions of the highway and rail networks; detailed representation of the waterway network; intermodal passenger connectivity database | Piecemeal representation of intercity and transit bus service coverage; little data on social service and non-profit transportation coverage |
Condition and performance | Condition and reliability of highways by segment, transit by property, and inland waterways by facility; reliability of commercial aviation by flight and airport | Condition and reliability of freight railroads; non-comparable throughput data among ports; condition of urban bus and rail transit maintenance facilities, and rail transit infrastructure |
