Caltrans Earth (CT Earth) visually brings together the vast amount of transportation and land use information compiled throught the CIB. CT Earth provides a web-based data access, sharing and viewing tool through a California-focused virtual world created by Caltrans and built on proven technology developed by Google.
CT Earth helps Caltrans, other state agencies, and eventually, the general public to make better decisions about our transportation system.
CT Earth offers an opportunity for everyone to view information in all phases of projects, including environmental planning, design, construction, and operations. This information includes state highways, rail, transit facilities, environmental resources, current and planned projects, and more. |

To combine resources and create a consistent set of data, Caltrans has joined with the California Association of Councils of Governments and regional agencies to develop and implement the 2012 California Household Travel Survey.
Regional travel models and the Statewide Travel Demand Model use statewide multimodal regional and interregional household travel behavior surveys during model development to be able to forecast travel behavior. |
