SB 743 Implementation Resources

Caltrans provides resources for developers, local governments, and others seeking information on how to implement projects that support the goals of SB 743 and benefit their communities.

Transportation Impact Study Guide (TISG)  (PDF)

The TISG details how the Caltrans Local Development Review (LDR) program reviews a land use project's VMT.

Updated Interim LDR Safety Review Guidance (PDF)

This document provides immediate direction about the safety review process while Caltrans develops a new, simplified safety review approach in the review of land use projects. 

Transportation Analysis Framework (TAF)* (PDF)

The TAF details methodology for calculating induced demand for capacity increasing transportation projects on the State Highway System.

Transportation Analysis Under CEQA (TAC)* (PDF)

The TAC provides guidance for making CEQA significance determinations for transportation projects along the State Highway System.

*Important updates to the First Edition of the TAF and TAC are posted to the "Bulletins" and "Hot Topics" sections on this page. 

SB 743 Environmental Essentials in Project Development and Delivery (PDF)
This white paper summarizes some of the challenges and best practices involved in implementing SB 743.

CARB 2017 Scoping Plan (link)

This plan includes technical information on what level of statewide VMT reduction would promote achievement of statewide GHG emissions reduction targets.

OPR CEQA Guidelines (PDF)
The guidelines for implementing SB 743 are on pages 11 and 12 of the California Environmental Quality Act (CEQA) Guidelines (Title 14, Division 6, Chapter 3 of the California Code of Regulations).

Technical Advisory (PDF)

This technical advisory is one in a series of advisories provided by the Governor’s Office of Planning and Research (OPR) as a service to professional planners, land use officials, and CEQA practitioners, in evaluating transportation impacts in CEQA.

California VMT Data (link)
This page includes trends in vehicle miles traveled (VMT) in California and will be updated as new data emerges.

NCST Induced Travel Calculator
This tool allows users to estimate annual VMT as a result of highway expansion. 

California Emissions Estimator Model (CalEEMod)
CalEEMod quantifies ozone precursors, criteria pollutants, and greenhouse gas emissions from the construction and operation of new land use development and linear projects in California. The model integrates data from CalEnviroScreen®, Cal-Adapt®, and the Healthy Places Index (HPI)® to identify potential climate risks and environmental, health, and equity burdens within the project vicinity.

Mitigation Playbook (DRAFT) (PDF)
This guide, developed by the Caltrans SB 743 Program, describes various quantifiable mitigation methods for VMT induced by highway capacity projects.

Fehr & Peers TDM+ (Beta)
TDM+ is a quick response, excel-based tool developed by Fehr & Peers to assist in calculating VMT reductions from the strategies presented in the 2021 CAPCOA Report Handbook for Analyzing Greenhouse Gas Emission Reductions, Assessing Climate Vulnerabilities, and Advancing Health and Equity. Its interface is designed to allow the user to update the inputs for each measure based on the specific attributes of a project or plan, as well as to pre-populate certain default values based on the project location. This version of TDM+ is currently in beta-testing.

The legal CEQA jargon of SB 743 can be difficult to communicate simply. Our fact sheets below can help ease that process. 

SB 743 Fact Sheet (Overview)

SB 743 Fact Sheet (Technical)

A common misconception is that a reduction in VMT will remove access to destinations. Our short video series, "SB 743: Rethinking How We Build So Californians Can Drive Less", helps to dispel these misconceptions and clarifies how we are thinking about this new paradigm.

Evaluation of Sketch-Level Vehicle Miles Traveled (VMT) Quantification Tools (link)
National Center for Sustainable Transportation "researchers compare and evaluate VMT estimation tools across a sample of land use projects. They compare the results from different tools for each project, consider the applicability of methods in particular contexts and for different types of projects, and assess data needs, relative ease of use, and other practical considerations." The research is not done within a CEQA context, but it is interesting to review the use of the VMT estimation tools. 

SB 743 Case Studies (link)
The Urban Sustainability Accelerator at Portland State University created five case studies on how to apply the VMT metric to a highway project and three land use projects.

Guidelines for Transportation Impact Studies in the San Diego Region (May 2019) (link)
The San Diego Section of the Institute of Transportation Engineers (ITE) has prepared updated regional Transportation Impact Study Guidelines to incorporate SB 743.

Partnership with Governor's Office of Planning and Research

Caltrans partners with the Governor's Office of Planning and Research (OPR) to provide advisory documents, guidelines, and other tools to support the implementation of SB 743, including the coordination of the Caltrans-OPR SB 743 Implementation Working Group
