The most current information about the value and uses of the CTPP data can be found in the CTPP Status Report.
CTPP Captures Essential Data About Your Community
The Census 2000 long form asks for information on such household and travel characteristics as:
- Household size, income, and vehicle availability
- Worker age, gender, occupation, and earnings
- Work location
- The usual departure time, travel mode, and travel time to work
The CTPP summarizes the long form records into tables designed by and for transportation planners. These tables are consistent with tables from previous transportation census packages (1990 CTPP and 1980 UTPP). Local governments worked with the Census Bureau to define traffic analysis zones (TAZs) for the tabulation.
The tables summarize characteristics by:
- Place of residence
- Place of work
- Place of residence by place of work
The tables can be used as is, exported into other analysis programs, or used to generate GIS maps and other forms of data presentation. CTPP helps you present complex data to the general public and decision makers.
CTPP helps you understand current conditions. You can:
- Analyze the effectiveness of the existing transportation system in serving the mobility needs of the population
- Analyze commuting and demographic trends over 10 or 20 years
- Plan new transit services and improve existing routes to serve specific populations
- Design and weight household travel surveys
CTPP helps you develop tools to examine future conditions. You can:
- Build and calibrate travel demand forecasting models
- Project the level of congestion along a specific corridor
- Forecast the potential market for new or expanded highway or transit facilities
- Forecast vehicle emissions for compliance with the Clean Air Act.

"CTPP data serves as the foundation for transportation planning and policy analyses performed by state DOTs and metropolitan planning organizations. It serves as the basis for understanding changes in travel patterns as well as changes in socio-economic trends affecting travel. It is a primary source of information for developing travel demand models, as well as for analyses that influence transportation policy. The CTPP 2000 is a resource that all state DOTs and MPOs should use."
