Division of Operations

Ali Zaghari
Deputy District Director for Operations

In partnership with others, we enhance the operation of the State Highway System to facilitate and optimize the movement of people, goods, and services in a safe and efficient manner. We respond to the needs and concerns of the public and elected officials, providing quality and efficient customer service, traffic improvements, and transportation management systems. We promote and support strategies to reduce the demand on the transportation system and thereby improve traffic flow.


Operations Offices

  • ITS
  • Traffic Engineering - South
  • Traffic Engineering - North
  • Traffic Design
  • Permits
  • District Traffic Manager
  • Systems Performance
  • Corridor Management


Leading the way in the Intelligent Transportation Systems (ITS), the Office of ITS in partnership with other internal and external partners, develops, integrates, implements, and supports an end-to-end transportation management system ranging from the Los Angeles Regional Transportation Management Center (LARTMC) to the Transportation Management System (TMS) field infrastructure in District 7.

Using new technology, the Office of ITS is responsible for transportation management system development and operations support which; integrates recurrent/non-recurrent incident detection, verification, incident response, planned events of freeway management, and field element operational control.

The Office of ITS also provides technical support for the LARTMC, TMS field elements, the LARTMC/TMS communications system, and associated hardware and software. Our goal is to use new technology to optimize utilization of the transportation facility, by optimizing freeway capacity, efficiency, safety, and information sharing with transportation agencies and other public and private sector entities.


The mission of the Offices of TE, North & South is to be a leader in Transportation System Management & Operations (TSMO) through the application of best practices that embrace most effective operational strategies and techniques, and state-of-the-art technology. We strive to make a difference in the quality of life for our customers. Some of our key responsibilities include but are not limited to:

  • Conduct highway traffic engineering safety and operations investigations
  • Respond to requests from concerned citizens, elected officials, and partner agencies
  • Prepare traffic engineering reports
  • Perform Local Development/Inter-Governmental Reviews
  • Conduct Encroachment Permit and project development quality reviews
  • Provide traffic engineering expertise to other functional units within the organization
  • Initiate State Highway System safety and operational improvement projects
  • Develop and implement Transportation System Management and Operations (TSMO) concepts and strategies
  • Work closely with local and regional partner agencies and the private sector, to plan, and develop solutions and strategies that address transportation needs and problems within the region


The focus of the Office of Traffic Design is to develop and deliver traffic safety and operation related civil, roadway signage, electrical, and lighting system projects within the greater Los Angeles and Ventura Counties. Our team strives to attain 100% in meeting quality and project delivery commitments supporting the Capital Outlay Program while fostering continuous improvement and efficiency gains in business operations. We also seek to provide the highest customer service in response to the Encroachment Permit reviews and Highway Maintenance projects.


The mission of the Office of Permits is to facilitate the use of the State Highway System by non- Caltrans entities for non-Caltrans related projects. In this respect, the Office of Permits aims to assist non-Caltrans entities to expediently develop their projects while maintaining public safety, convenience, and highway integrity.

District 7 Permits Public Counter is located at:
100 South Main Street, Suite 100, Los Angeles, CA 90012
(213) 897-3631 or (213) 897-0420.


The office of District Traffic Manger (DTM) is responsible to ensure the state highway system is operated safely, smoothly, and efficiently through a combination of a number of system management strategies.

The office utilizes the following system management strategies:

  • Los Angeles Transportation Management Center (LARTMC) – The LARTMC is operated by the California Department of Transportation (Caltrans) and the California Highway Patrol (CHP) in a cooperative effort to provide integrated transportation management and improved system performance. Intelligent Transportation System (ITS) tools such as closed circuit television (CCTV) cameras, changeable message signs, highway advisory radio (HAR) broadcasts, and traffic monitoring stations are used to monitor and manage the transportation systems, and notify the traveling public of real-time highway conditions. In addition, all planned lane and full highway closure requests for construction, maintenance, and encroachment permit activities are reviewed and approved through the Office of District Traffic Manager to ensure the safety and efficiency of the system is maintained.
  • Traffic Management Teams (TMT) – A TMT is deployed to the site of an incident to improve safety and reduce congestion by warning/informing the motoring public of real-time unexpected conditions ahead. The use of changeable messages signs, either truck or trailer mounted are dispatched for the following, but not limited to these situations:
    • Road and lane closures
    • Detours
    • Delays


This office collects, analyzes, and compiles transportation system data to evaluate performance of the State Highway System within the Los Angeles and Ventura Counties. We monitor Transportation Management System (TMS) elements such as ramp meters, changeable message signs, and freeway cameras, and ensure proper functioning. Our functions enable decision makers to make data-driven and performance-based decisions about transportation infrastructure.

The Office consists of branches covering System Monitoring, System Modeling, High Occupancy Vehicles (HOV) and Express Lanes, Traffic Census, Truck Services, Park and Ride Facilities, and Performance Evaluation of the State Highway Operations and Preservation Program.


The Office of Corridor Management (A) is responsible for day-to-day Transportation Systems Management and Operations (TSMO), safety improvement activities and the overall performance of the assigned corridors.

The products and services delivered include safety and mobility improvements, congestion reduction strategies, coordinated, integrated multimodal system management techniques and best practices to yield optimized transportation system performance for travelers, commercial vehicle operators, bicyclists and pedestrians.

This office also leads the district’s efforts to research, develop, test, and deploy a framework for the statewide connected Corridors Program focused on corridor transportation system management, with its Pilot Project (Pilot) currently in construction along Interstate 210. The Pilot is led by Caltrans with assistance from LA Metro and California Partners for Advance Transportation Technology (PATH) at UC Berkeley; it will encompass the entire multi-modal transportation network to seek opportunities to move the motoring public and goods in the most efficient and safest manner possible.
