By providing administrative support at the District Office, Diana Riveros was exposed to the operations of each Caltrans division and respective units, which helped her to receive an opportunity to continue an internship within the I.T. Unit. Working with engineers on current projects, Angelica Rojas-Colin gained firsthand knowledge and acquired skills that engineers use on a daily basis. Juan A. Roman’s Caltrans work afforded him the exposure to the roadway and structures inspection process at a construction site, here he feels he could see himself in the future. By working with the Ramp Metering Branch, Karen Vera learned about Caltrans’ commitment to implementing effective ramp metering strategies to keep freeways operating at their optimum flow rates. Through the process of managing freeway flow through ramp metering, Thomas Aristide gained both the skills and realization that the collection of accurate data is the cornerstone for improving the performance of a managed system. This internship has helped us acquire skills that are beneficial for our future engineering careers. RESULTS • Diana - • Facilities is a key unit within the Administration Division of District 11. It is responsible for addressing employee inquiries, the oversight of security and facilities operations of all District 11. • Angelica - • Microstationand ArcGIS are essential tools to help engineers design, model, visualize, document, map, and sustain infrastructure projects. • Juan - • The construction of the 905 Freeway was necessary to reduce traffic from the Otay Mesa Port of Entry to the State Route 805 and Interstate 5, in San Diego County. • Karen and Thomas - • The Ramp Metering Branch uses the RMIS System for setting, controlling and optimizing ramp meters to increase traffic flow and decrease congestion on freeways. • The Caltrans Freeway Performance Measurement System (PeMS) receives and archives data from RMIS for more detailed traffic data analysis. The mission of California’s Department of Transportation (Caltrans) is to improve mobility across the state. Caltrans aims to accomplish their mission in all 12 districts through five strategic goals: safety, mobility, delivery, stewardship and service.
