Vehicle Miles Traveled (VMT) / SB743 Compliance
Partnering with SANDAG, LLG is an industry leader in determining VMT, and has co-authored a white paper detailing the methodology developed for calculating VMT using the SANDAG regional travel demand model.
The State of California Governor’s Office of Planning and Research (OPR) released draft guidelines per the requirements of Senate Bill 743 (SB 743) on July 1st, 2014. The recent guidelines embrace VMT as a new, and in certain cases, more relevant metric.
Since the publishing of LLG’s white paper, the firm has continued to immerse itself into the increasingly important field of alternative measures of effectiveness for traffic analyses. LLG extrapolates various types of data from the SANDAG-required model and other models for use in environmental assessments. LLG/SANDAG received the Most Educated About GIS award for the development of the VMT Analysis Methodology presented at the 2013 ESRI International GIS Conference.
LLG data includes:
- Vehicle Miles Traveled (by time of day, road type, and speed)
- Vehicle Hours Traveled (by time of day, road type, and speed)
- Average Trip Lengths (by area, or by mode)
- Truck Percentages (by truck type)
- Vehicle/Person Miles by Mode (private vehicle, carpool, transit, walk, etc.)

LLG coordinated extensively with City staff, SANDAG and the environmental consultant to assist in the determination of vehicle miles traveled (VMT) for the required Climate Action Plan (CAP) analysis. LLG was involved in coordinating the SANDAG traffic modeling to develop VMT for various scenarios. This work was used to assist with the preparation of suitable technical reports for incorporation into the EIR. A full EIR-Level Traffic Impact Analysis was also prepared for the project.

Linscott, Law & Greenspan Engineers (LLG), together with SANDAG, co-authored a technical white paper detailing the developed methodology for calculating Vehicle Miles Traveled using a Travel Demand Model. The white paper describes the analytical approach for disaggregating VMT into usable data to be applied to a calculation of transportation emissions for a Green House Gas analysis of a particular study area. This method is based on the standards for best practices for developing local community GHG emissions requirements published by the International Council for Local Environmental Initiatives. The white paper was approved for publishing in June 2013 by the San Diego section of the Institute of Traffic Engineers Transportation and Mobility Task Force.

LLG’s SANDAG co-author for developing the VMT Analysis Methodology presented at the 2013 ESRI International GIS Conference and received the award for the Most Educated About GIS. The award submission presented the problem statement of identifying an effective and accurate method for forecasting Vehicle Miles Traveled for large-scale land use projects. The presenters prepared an oversized poster depicting the key components of the analysis process complete with data tables and illustrations. The award was officially recognized and congratulated by the SANDAG Board of Directors at their November 2013 meeting.
