SRTA identifies current and projected future transportation needs and, through detailed planning studies, devises strategies to address those needs.  In partnership with the appropriate city or county agency and Caltrans, special studies are conducted for select corridors, road segments and key locations to evaluate safety concerns, prepare project alternatives and cost estimates, and devise appropriate actions to resolve issues.  SRTA periodically is consulted to review project environmental impact reports (EIRs), project study reports (PSRs) and Caltrans transportation concept reports (TCRs).
