The CTPP summary tables can be used to create a wide variety of charts, graphs, and maps to communicate information.
The most current information about the value and uses of the CTPP data can be found in the CTPP Status Report.
Existing Conditions: CTPP's TAZ-level information about existing travel patterns makes it particularly useful in corridor analysis and condition assessments. Graphically displaying commuter flows and travel times can immediately assist planners and decision-makers in understanding the dynamics of the transportation system more accurately and more completely.
Short-Term Planning: CTPP enables planners to design near-term improvements to transit and roadway systems. In the CTPP, worker characteristics such as age, household income, and vehicle availability are tabulated by commute mode. Route design may be adjusted to maximize service to specific population groups. Information on low-income workers and their commute characteristics can be used to design and improve welfare-to-work programs.
Trend Analysis: When combined with the 1990 CTPP and/or the 1980 UTPP (Urban Transportation Planning Package), the CTPP 2000 provides transportation planners with an unprecedented level of information about population, households, employment, and commuter trends. For the United States as a whole, the trend from 1990 to 2000 is a continued increase in vehicle ownership and decline in carpooling for the journey-to-work. CTPP allows examination of local trends compared to the nation, and to areas of similar size.
Equity and Mobility Analysis: CTPP helps transportation planners estimate the impact of transportation programs on different groups of communities. CTPP can be used to identify spatial distributions of different groups, such as minorities, people with disabilities, and people in poverty. This allows evaluation of regional transportation accessibility by race and income groups.
