Los Angeles seemingly has it all – the glitz and glamor of Hollywood, sweeping hill and canyon-side views and 329 average days of sunshine annually to enjoy on one of many beaches.
The U.S.’s most populated county probably won’t be the first to pop up in an internet search of “transportation efficiency,” though. In fact, Los Angeles motorists spent more than 100 hours battling traffic congestion last year, earning the city a top spot on INRIX’s?Global Traffic Scorecard?for the sixth consecutive year in 2018.
But what if we showed you how dynamic travel planning and connected vehicle technology – implemented by one Los Angeles transportation agency with support from Jacobs – is clearing truck travel congestion, and the air while at it?

Connected vehicles research has been on-going for nearly two decades. These types of local projects are needed to further advance the deployment of connected vehicle technology while also addressing real-world local transportation system needs. This project will give Los Angeles a head start in reaping the countless safety, mobility and environmental benefits which connected vehicle infrastructure and applications are expected to bring.
Fueling mobility in southern California
An integral link in southern California’s transportation system, the I-710 South Corridor is the primary route in and out of the Ports of Long Beach and Los Angeles. Together these container ports, the two largest in the U.S., handle 25 percent of the nation’s export traffic and 40 percent of import traffic.
By 2035, the volume of freight and associated truck traffic along the corridor is expected to more than double – elevating severe congestion problems, including truck trip delays in and near the ports, and general traffic congestion for metropolitan area highways and arterials.
Ahead of these headaches, the Los Angeles County Metropolitan Transportation Authority (Metro) is leading an effort to build on the U.S. Department of Transportation’s Freight Advanced Traveler Information System (FRATIS) research, which began in 2012.?Metro’s offshoot, called Drayage, Freight, and Logistics Exchange (DrayFLEX) , is now underway and will look to build upon previous concepts and deployments to explore how connected vehicle technology can improve goods movement, especially on Los Angeles’ roadways.
Aiming to provide freight-specific dynamic travel planning information to improve container movement in and around the ports, the project uses information from the marine terminal operators, trucking companies and traveler information systems to provide status updates on container availability, enable trucking companies to set up automated appointments and provide truck drivers the best routes to use to and from the port.?Metro is testing the system on a fleet of 500 trucks throughout the current four-year project period, and Jacobs, as a member of the Cambridge Systematics team, is providing the planning, design and deployment of connected vehicle applications on freight trucks.
Letting data do the talking
Integrating data from various resources including 3rd party data for port wait times, 511 for incident alerts and traffic and the California Department of Transportation and California Highway Patrol for road closures and restrictions, DrayFLEX helps streamline the efficiency of goods movements in and around the ports and along the I-710 South Corridor.
Using the integrated data, DrayFLEX provides messaging between the marine terminal and the fleets, essentially creating digital “handshakes” that signal container availability and dispatches for truck movement – helping balance early or late arrivals.?Daily truck itineraries are then optimized for each driver – using data collected on average stop times, predicted travel times and expected downtime – to unlock potential truck optimizations that translate to fewer truck miles and improved air quality.
Connections for the future
Adding connected vehicle technology to the DrayFLEX development opens the possibilities for seamless communication between the marine terminal and the fleets even more. ?Possible implementations may include dedicated short-range vehicle-to-vehicle communication and radar sensors and electronic engine control that could reduce energy consumption and improve traffic flow, while maintaining safety. As part of the DrayFLEX Project, the team is also studying additional connected vehicle applications focused on mobility, safety and the environment to provide even greater optimization.
DrayFLEX not only provides better management of truck traffic on freeways and arterials, but also improves flow of containers to and from distribution centers and reduces turn and waiting time at the ports. Reducing traffic congestion during peak times will be crucial as ports and roadways look to handle expected superships of 15,000 20-foot equivalent units (TEU) or greater soon.
The project is a key element in Metro’s larger The Gateway Cities Technology Plan for Goods Movement effort, that, in coordination with Gateway Cities Council of Governments, will provide a blueprint for an end-to-end information support system that can improve the efficiency of goods movement in southern California through the integration of traditional real-time road and traveler information technologies, along with intermodal freight, port and truck technologies.?These enhancements to goods movement will supplement the larger capacity enhancements and operational improvement projects underway on the I-710 South Corridor, which Jacobs is also supporting to help find ways to make the corridor safer and easier to drive, improve air quality and public health and improve the freeway's design and traffic flow.
