Insights from Driver Parking Decisions in a Truck Simulator to Inform Curb Management Decisions
Published:
2023
Authors: Dr. Andisheh Ranjbari, Dr. Anne Goodchild, Dr. Ed McCormack, Rishi Verma

Summary:

Millions of people who live and work in cities purchase goods online. As ecommerce and urban deliveries spike, there is an increasing demand for curbside loading and unloading space. To better manage city curb spaces for urban freight, city planners and decision makers need to understand commercial vehicle driver behaviors and the factors they consider when parking at the curb.

Paper
How Cargo Cycle Drivers Use the Urban Transport Infrastructure
Published:
2023
Authors: Dr. Giacomo Dalla Chiara, Griffin Donnelly, Şeyma Güneş, Dr. Anne Goodchild
Publication: Transportation Research Part A: Policy and Practice
Summary:

While electric cargo bikes can be viable and environmentally sustainable for urban goods delivery, they are not yet widely used in the U.S. In this study, researchers studied the behaviors of a group of bike delivery drivers to gain an understanding of the challenges they face, how they make decisions about where to park, what factors influence whether they use the travel lane, bicycle lane, or the sidewalk, and the effectiveness of these decisions.

Report
Supporting Comprehensive Urban Freight Planning by Mapping Private Load and Unload Facilities
Published:
2023
Authors: José Luis Machado León, Gabriela Girón-Valderrama, Dr. Anne Goodchild, Dr. Ed McCormack
Summary:

Freight load and unload facilities located off the public right-of-way are typically not documented in publicly available databases. Without detailed knowledge of these facilities, i.e. private freight load and unload infrastructure, cities are limited in their ability to complete system-wide freight planning and to comprehensively evaluate the total supply of load and unload spaces in the city.

Paper
Do Parcel Lockers Reduce Delivery Times? Evidence from the Field
Published:
2023
Authors: Dr. Andisheh Ranjbari, Caleb Diehl, Dr. Giacomo Dalla Chiara, Dr. Anne Goodchild
Publication: Transportation Research Part E: Logistics and Transportation Review
Summary:

Common-carrier parcel lockers have emerged as a secure, automated, self-service means of delivery consolidation in congested urban areas, which are believed to mitigate last-mile delivery challenges through reducing out-of-vehicle delivery times and consequently vehicle dwell times at the curb. However, little research exists to empirically demonstrate the environmental and efficiency gains from this technology.

Report
Analysis of Online Shopping and Shopping Travel Behaviors in West Seattle
Published:
2023
Authors: Dr. Anne Goodchild, Dr. Giacomo Dalla Chiara, Rishi Verma, Kelly Rula
Summary:

The purpose of this research is to explore consumers’ online shopping and in-person shopping travel behaviors and the factors affecting these behaviors within the geographical context of the study area of West Seattle.

Paper
COVID-19 Impacts on Online and In-Store Shopping Behaviors: Why they Happened and Whether they Will Last Post Pandemic
Published:
2023
Authors: Dr. Andisheh Ranjbari
Jorge Manuel Diaz-Gutierrez (Pennsylvania State University, Helia Mohammadi-Mavi (Pennsylvania State University)
Publication: Transportation Research Record: Journal of the Transportation Research Board
Summary:

Throughout the COVID-19 pandemic, people’s online and in-store shopping behaviors changed significantly. As the pandemic subsides, key questions are why those changes happened, whether they are expected to stay, and, if so, to what extent. We answered those questions by analyzing a quasi-longitudinal survey dataset of the Puget Sound residents (Washington, U.S.).

Paper
An Empirical Analysis of Passenger Vehicle Dwell Time and Curb Management Strategies for Ride-Hailing Pick-Up/Drop-Off Operations
Published:
2023
Authors: José Luis Machado León, Dr. Anne Goodchild
Don MacKenzie (University of Washington College of Engineering)
Publication: Transportation
Summary:

With the dramatic and recent growth in demand for curbside pick-up and drop-off by ride-hailing services, as well as online shopping and associated deliveries, balancing the needs of roadway users is increasingly critical. Local governments lack tools to evaluate the impacts of curb management strategies that prioritize different users’ needs.

Technical Report
NYC Zero-Emissions Urban Freight and Green Loading Zones Market Research
Published:
2022
Authors: Thomas Maxner, Nota Goulianou, Dr. Andisheh Ranjbari, Dr. Anne Goodchild
Summary:

In an effort to reduce emissions from last-mile deliveries and incentivize green vehicle adoption, The New York City Department of Transportation (NYC DOT) is seeking to implement a Green Loading Zone (GLZ) pilot program. A Green Loading Zone is curb space designated for the sole use of “green” vehicles, which could include electric and alternative fuel vehicles as well as other zero-emission delivery modes like electric-assist cargo bikes.

Article
Local Area Subset Row Inequalities for Efficient Exact Vehicle Routing
Published:
2022
Authors: Amelia Regan
Udayan Mandal, Julian Yarkony
Publication: arXiv e-prints (2022): arXiv-2209
Summary:
In this research we consider an approach for improving the efficiency and tightness of column generation (CG) methods for solving vehicle routing problems. This work builds upon recent work on Local Area (LA) routes.
