This brief discusses studies highlighting the institutional challenges the Port of Los Angeles and Port of Long Beach face while working with a multitude of stakeholders and regulatory bodies to address both environmental sustainability and economic competitiveness.

Automated Vehicles and Central Business District Parking: The Effects of Drop-Off Travel on Traffic Flow and Vehicle Emissions

Principal Investigator Caroline Rodier, Ph.D.
University of California, Davis

Automated vehicles have the potential to reduce the need for parking, but they also have the potential to increase congestion through picking up and dropping off passengers. This project studies such possible environmental effects.

Centrally Coordinated Schedules and Routes of Airport Shuttles with LAX Terminals as Application Area

Principal Investigator Petros Ioannou, Ph.D.
University of Southern California

The purpose of this project is to develop a CENtrally COordinated Shuttle system (CENCOS) which can effectively coordinate airport shuttle schedules and routes in order to minimize curb congestion at the pick-up and drop-off points, reduce operational cost, improve quality of service with considerable benefits to mobility and environment.

Research Report

In this project, the authors developed a centrally coordinated shuttle scheduling and routing management system for mixed fleets of diesel and electric shuttles using a digital twin of LAX to LA downtown traffic road network by optimizing the total combined cost of energy consumption and travel time.

Research Report

This study proposes a mathematical model that solves the empty container problem using double and single container trucks.

Congestion Reduction Through Efficient Empty Container Movement Under Stochastic Demand

Research Product Type

Research Report

n this work, the authors developed a scheduling assignment for loaded and empty containers that builds on earlier models but incorporates stochastic (random) future demand. This report shows that the truck miles needed to satisfy the demand at all locations is reduced by about 4-7% when considering future stochastic demand as opposed to only considering today’s demand.

Congestion Reduction via Personalized Incentives

Research Product Type

Research Brief

Researchers at the University of Southern California developed a real-time, distributed algorithm for offering personalized incentives to individual drivers to make socially optimal routing decisions.
