California Department of Transportation



The Caltrans Division of Research and Innovation has been in the forefront of the effort to improve the efficiency and attractiveness of modal systems throughout the state. By making public transportation more efficient, more comfortable, and more dependable, it will grow in importance as a traveler's choice. Benefits such as efficient integration of land use and transportation, congestion relief, and air quality improvements can occur as a result.

Master agreements with the University of California, and standard agreements with other research institutions, facilitate research partnerships and lend continuity to annually-programmed tasks.
