TFIC Documentation

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

Forecasted average weekday traffic (AWT) 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) zone connector volumes are shown and TAZ-level trip generation and land use forecasts are provided.

Source. SANDAG uses a regional transportation model to produce highway and transit forecasts for individual forecast years. These forecasts are updated periodically to incorporate the most recent planning assumptions. Traffic Series 12 forecasts were completed in October 2013 in support of the 2011 2050 Regional Transportation Plan (RTP). These traffic forecasts utilize the "Revenue Constrained" network as defined in the RTP, and the Final Series 12 2050 Regional Growth Forecast.

Series 12 forecasts differ from the TFIC Series 11, which was based on the Regional Transportation Plan (RTP) adopted in 2008 and Series 11 growth forecasts.
