Community Capture Methodology

The Department has begun to develop a methodology for analyzing the external traffic impacts of self-contained new communities. Transportation planners identified the need for this methodology during the development of regional impact (DRI) review process for several major new towns planned in Florida. We have started using the term "Community Capture" as the way to describe the unique trip internalization of new communities, separated from existing urban areas.

Relying on previous trip generation and internal capture studies as well as reviewing the latest research, we have developed a starting methodology for analyzing the impacts of these new communities.

We have produced the principles of a methodology for self-contained communities, with some guidance on using regional modeling techniques and supported by significant plans for comprehensive monitoring of external traffic.

This methodology has undergone peer review by many interested people from all sectors of planning, development, and transportation engineering. The methodology will be included in the Transportation Impact Handbook, now being developed.

This methodology is a framework for the study process and will be augmented as additional information is available. Please continue to check here for the latest version.

Community Capture Methodology

Some of the documents we used to help us are listed below.

Resource Documents

• Trip Characteristics of New Self-Sustaining Communities - Acrobat version of the presentation showed in the July 14, 2008 Video Conference. Setting stage for our study.
• Internal Capture Studies in a Spreadsheet - A “work in progress” Excel spreadsheet with some information on new communities, reported capture rates, acres, and population. Note: Data is rough and unverified and we can use any help, suggestions, or corrections.
• District 4 - Trip Characteristics Study of Multi-Use Developments - Final Report of 1993 study done for District 4 FDOT (FT. Lauderdale Office) on the internal capture of some communities in Southeast Florida - Done by Tindale - Oliver. Note: The three communities studied in this report are the basis of all the factors in the ITE method of determining internal capture.
• District-wide Trip Generation Study (District 4) - Final Report of 1995 study done for District 4 FDOT (FT. Lauderdale Office) on the internal capture of some communities in Southeast Florida. Done by Walter Keller
• Internalizing Travel by Mixing Land Uses: Study of Master-Planned Communities in South Florida - The report on Reid Ewing's work on Southeast Florida community internal capture based on the travel diaries of people answering the year 2000 South Florida Travel Survey.
• Traditional Development Trip Generation Characteristics - Brent Lacy article summarizing various internal capture studies from around Florida. Published in FLITE (Florida Institute of Transportation Engineers magazine in September 2005). Note: Mr. Lacey used much data from the work by Reid Ewing's study “Internalizing Travel by Mixing Land Uses.”
