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.

Summary:
Throughout the COVID-19 pandemic, 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.).

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. Urban freight transportation is a diverse phenomenon.

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. West Seattle is a peninsula located southwest of downtown Seattle, Washington State. In March 2020, the West Seattle High Bridge, the main bridge connecting the peninsula to the rest of the city, was closed to traffic due to its increased rate of structural deterioration.

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 by 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.

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.

Summary:
Electric cargo cycles are often considered a viable alternative mode for delivering goods in an urban area. However, cities in the U.S. are struggling to regulate cargo cycles, with most authorities applying the same rules used for motorized vehicles or traditional bikes. One reason is the lack of understanding of the relationships between existing regulations, transport infrastructure, and cargo cycle parking and driving behaviors.

Summary:
The last mile of delivery is undergoing major changes, experiencing new demand and new challenges. The rise in urban deliveries amid the societal impacts of the COVID-19 pandemic has dramatically affected urban logistics. The level of understanding is increasing as cities and companies pilot strategies that pave the way for efficient urban freight practices.

Summary:
Until recently, urban transport authorities often overlooked freight, concentrating their attention on the movement of people. Even when motivated to tackle urban freight, many city authorities find it difficult to mobilize their own resources, and address the complex set of differing views of a large variety of stakeholders. Historically, the role of city authorities, or local authorities within cities, has been confined largely to one of regulation as opposed to collaborative planning.

Summary:
The distribution of goods and services in North American cities has conventionally relied on diesel-powered internal combustion engine (ICE) vehicles. Recent developments in electromobility have provided an opportunity to reduce some of the negative externalities generated by urban logistics systems. Cargo e-bikes — electric cycles specially designed for cargo transportation — represent an alternative environmentally friendly and safer mode for delivering goods and services in urban areas.

Summary:
What do equity and social justice mean for urban freight planning and management? New Urban Freight Lab paper reviews transportation and mobility justice theory and finds that urban freight issues are absent from these discussions, which primarily concern passenger and personal mobility. When urban freight is considered, authors usually discuss topics such as emissions, pollution, congestion, noise, and collisions.

Summary:
The rise of ecommerce helped fuel consumer appetite for quick home deliveries. One consequence has been the placing of some logistics facilities in proximity to denser consumer markets. The trend departs from prevailing discussion on “logistics sprawl,” or the proliferation of warehousing into the urban periphery. This study spatially and statistically explores the facility- and region-level dimensions that characterize the centrality of ecommerce logistics platforms.

Summary:
Curbspace is a limited resource in urban areas. Delivery, ridehailing and passenger vehicles must compete for spaces at the curb. Cities are increasingly adjusting curb rules and allocating curb spaces for uses other than short-term paid parking, yet they lack the tools or data needed to make informed decisions. In this research, we analyze and quantify the impacts of different curb use allocations on curb performance through simulation.

Summary:
A year and a half ago, our members decided to dig into four topics for the Goods Movement 2030 project (Electrification, Digital Transformation, Planning Streets for People and Goods, and Microfreight). They all — public and private sector alike — saw these areas as transformative.

Summary:
It becomes easier to understand the barriers to scaling up cargo bikes for last-mile delivery when you hear Mark Chiusano, Owner/CEO of Cornucopia Logistics and affiliates, talk about the complexity of operations in New York City. Cornucopia works with Amazon (both companies are Urban Freight Lab members) to run a fleet of more than 100 cargo bikes making thousands of weekly deliveries for Amazon Fresh and Whole Foods locations in Manhattan.
