Land Use/Transportation Data & Tools
The Office of Smart Mobility and Climate Change has initiated, funded, and coordinated several studies and related efforts regarding housing, land use and transportation coordination, smart growth (including transit-oriented development and urban/suburban infill land uses), and the development of models and tools for assessing such strategies. A brief description of each of these, along with website links, are provided below.
Improved Data and Tools for Integrated Land Use-Transportation Planning in California - Click to ExpandUC Davis Urban Land Use and Transportation Center
Effective land use/transportation planning requires the ability to estimate the benefits and impacts of various choices, including those regarding “smart growth” and “sustainable communities” strategies (such as urban infill, mixed-use, transit-oriented development, complete streets, etc.). This project obtained and analyzed available data on quantitative relationships between the built environment and travel in various areas of California. It also incorporated the results into tools that regional agencies, Caltrans Districts, and cities & counties throughout California can use in land use-transportation planning processes, such as:
- Regional Plans: Blueprints; SB375-required Sustainable Communities Strategies and Regional Transportation Plans
- Local Government Plans: General, Specific Community, Infill, and Transit-Oriented Development Plans
The products that this project provided allow decision makers to consider potential effects of transportation and land use choices in a more consistent and supportable way than was previously possible. Overall, this project contributes to better-informed decisions resulting in more efficient land use and transportation systems with fewer impacts and greater benefits; resulting in more “livable” and “sustainable” communities.

Trip-Generation Rates for "Smart Growth" Land Uses in California - Click to Expand
In order to prepare traffic impact analyses of proposed land use development projects, professionals often rely on the Institute of Transportation Engineers’ (ITE) published trip generation rates. However, ITE data typically reflects isolated suburban development that lacks transit service as well as adequate pedestrian and bicycle facilities. As a result, the use of ITE trip-generation rates to analyze proposed development projects located in existing urban infill areas tends to significantly over-predict vehicular traffic impacts and underestimate trips made by transit, walking, and bicycling. In 2004, Caltrans initiated a major effort to provide multi-modal trip generation rates data for urban infill and other "smart growth" development projects in California. This effort has resulted in the following products:
1) Smart Growth Trip-Generation Rates Data and Adjustment Method
- Overview of Trip-Generation Rates Data for Infill and Transit-Oriented Land Uses
- Fact Sheet
- Final Project Report and Tool (UC Davis website)
2) California Urban Infill Trip-Generation Rates Study
a) Phase 1 Report: Data Collection Methodology and Pilot Application (2008)
This report describes results of the first phase of this effort. In this phase, a methodology for selecting and studying infill land uses was developed and described, and 13 initial sites were studied using this methodology.
- b) Final Summary Report: Trip-Generation Rates for Urban Infill Sites in California (July 2009)
This Final report summarizes the study's methodology, presents and analyzes trip-generation rates data for 26 urban infill sites in California, provides details regarding techniques and costs of collecting and analyzing data, and other related information.

Assessment of Local Models and Tools for Analyzing Smart-Growth Strategies - Click to Expand
Cities and counties use travel models and other analytical tools to assess the benefits and impacts of local land use plans, transportation improvements, and proposals for development projects. This report assesses the ability of available models and tools to adequately analyze “smart-growth” land use and transportation strategies (such as infill, mixed land uses, transit-oriented development, etc.). It also suggests ways that models and tools could be improved or enhanced.
Assessment of Integrated Transportation/Land Use Models - Click to ExpandFinal Report (2006)
This study explored several new “Integrated” (land use/economic/transportation) models and assessed whether and how they can improve the ability to understand benefits and impacts of a variety of transportation, economic, and land use strategies. The results of this effort led to a Caltrans-funded feasibility study of the potential implementation of a statewide Integrated model for interregional analyses (that will be completed in 2009).
