TFIC Documentation

The Transportation Forecast Information Center (TFIC) gives you quick access to SANDAG's regional transportation model forecasts. You may use this tool to look at the forecasts on screen as well as print maps or tables.

Forecasted average weekday traffic volumes (in thousands) are displayed for freeways, ramps, and major and minor roads. Individual roadway segments can be selected to obtain additional information including street name, type of roadway, number of lanes, and posted speed. Traffic Analysis Zone (TAZ) connector volumes are also displayed. A tool is included for selecting and zooming to Master Geographic Reference Area (MGRA) boundaries.

Data Sources: SANDAG uses an activity based regional transportation model (ABM) to produce highway and transit forecasts for Regional Transportation Plan (RTP) phase years. These forecasts are updated periodically to incorporate the most recent planning assumptions.

The Series 13 forecasts were completed in October 2015 in support of  San Diego Forward: The 2050 Regional Transportation Plan. These traffic forecasts utilize the "Revenue Constrained" network as defined in the RTP, and the Final Series 13 2050 Regional Growth Forecast.

Series 14 forecasts were generated to support the  2019 Federal Regional Transportation Plan adopted by the SANDAG Board of Directors on October 25, 2019.
