Enhancement of Cross-Town Improvement Project (C-TIP) Drayage Optimization Proof of Concept - Los Angeles/Long Beach, California

Summary Information

This project evaluated the deployment of a drayage optimization tool designed to use Freight Advanced Traveler Information System (FRATIS) data and Corridor Optimization for Freight (COfF) algorithms to improve trucking operations by reducing the number of unproductive truck drayage trips (short-haul freight movement) in the Los Angeles/Long Beach area of California.



METHODOLOGY



The project conducted from July through October 2017 included participation from one drayage company that provided data including pickup and delivery time windows, order numbers, driver names and numbers, city codes, delivery dates, as well as pickup and delivery street addresses for operations. In total, 101 days of data were provided by the participating company, with 85 days used for final analysis. Some days were discarded for reasons that included insufficient data and data affected by holidays.



The data collected was used to assess the performance of drayage operations with and without the optimization planning tool.

FINDINGS

Overall the project demonstrated the potential for the system to substantially reduce drayage mileage and improved operational efficiencies. Analysis of live operational data indicated that the deployment of FRATIS on the Los Angeles/Long Beach transportation network led to a 14 percent reduction in average total miles driven.
