Summary:
“Why deliver two-pound burritos in two-ton cars?” That’s the question posed by sidewalk delivery robot company Serve, which is delivering food in places like Los Angeles. Sure, using something other than a car for items like a burrito makes sense. But what about a sofa? Urban delivery is all about right-sizing, context, and connecting logically and efficiently to the broader delivery network.

Summary:
At the spring Urban Freight Lab (UFL) meeting, members heard about four innovative approaches to planning streets so both people and goods can move more efficiently, safely, and sustainably. The catch? Europe is the only place most of these ideas have successfully scaled. So, how might these ideas translate or get adapted to a North American context as we look toward 2030? In our last blog, we talked about an integrated freight and pedestrian approach Gothenburg, Sweden, has had on...

Summary:
Space is the scarcest resource in cities. How can we best use street space to do more for more street users? Mention the “space race” and it tends to conjure up the Cold War-era competition between the United States and the then-USSR to “conquer” outer space. But at the winter meeting of the Urban Freight Lab (UFL), members heard about a different race playing out on our streets right under our noses. It’s what Philippe Crist of the International Transportation...

Summary:
Consider it the left-hand, right-hand challenge of the urban freight landscape. But a gentler riff on the whole “the left-hand doesn’t know what the right hand is doing.” Each hand does know something about what the other hand is doing, but probably not enough. On the left, there are Urban Freight Lab (UFL) member companies like Amazon and UPS that use the public right of way to move goods. On the right, various levels of government manage and regulate that...

Summary:
We’ve dug into how digitization continues to spark new developments in the urban freight landscape across the private and public sectors alike — with cities lagging behind digitization veterans like Amazon. As Urban Freight Lab members noted at the fall meeting, it’s understandable why the private sector is ahead. Digitization helps companies improve operations toward lowering costs, saving time and money, and keeping customers satisfied.

Summary:
We have digitization to thank for today’s urban freight landscape. Digitization has long been the backbone of things we now take for granted — from TNCs (Transportation Network Companies) Uber and Lyft to online shopping and the complex supply chain needed to make that ecommerce happen. Digitization is what gives ecommerce’s biggest player — Amazon — visibility into its packages and enables it to deliver faster and more reliably than ever. So digitalization isn’t new.

Summary:
Urban freight deliveries using microhubs and e-cargo cycles have been gaining attention in cities suffering from congestion and emissions. E-cargo cycle deliveries and microhubs used as transshipment points in urban cores can replace trucks to make cities more livable. This study describes and empirically evaluates an e-cargo tricycle pilot conducted with multi-sector stakeholders in Seattle to report the potential benefits and pitfalls of such practices.

Summary:
Urban distribution centers (UDCs) are opening at unprecedented rates to meet rising home delivery demand. The trend has raised concerns over the equity and environmental justice implications of ecommerce’s negative externalities. However, little research exists connecting UDC location to the concentration of urban freight-derived air pollution among marginalized populations.

Summary:
With growing freight operations throughout the world, there is a push for transportation systems to accommodate trucks during loading and unloading operations. Currently, many urban locations do not provide loading and unloading zones, which results in trucks parking in places that obstruct bicyclist’s roadway infrastructure (e.g., bicycle lanes).

Summary:
Three different data types were obtained from Oregon State Driving and Bicycling Simulator Laboratory for purpose of this report and they are as follow: Speed data consists of subject number, average speed, minimum speed, and all the independent variables. Speed data were collected based on the truck’s speed while driving through a certain scenario (out of 24).

Summary:
Urban freight denotes vehicle and commodity flows in an urban environment. These flows depend on a complex set of relationships among various stakeholders. In the last decades, urban freight has experienced an incredible pace of evolution, which has occurred due to various technological factors. One example is the ubiquity of internet access and the advance in information technology, leading to e-commerce adoption.

Summary:
Transit transfers are a necessary inconvenience to riders. They support strong hierarchical networks by connecting various local, regional, and express lines through a variety of modes. This is true in Seattle, where many lines were redrawn to feed into the Link Light Rail network. Previous transfer studies, using surveys, found that perceived safety, distance, and personal health were significant predictors of transfers.

Summary:
This paper provides an approximation method for the optimization of isolated evacuation operations, modeled through the recently introduced Isolated Community Evacuation Problem (ICEP). This routing model optimizes the planning for evacuations of isolated areas, such as islands, mountain valleys, or locations cut off through hostile military action or other hazards that are not accessible by road and require evacuation by a coordinated set of special equipment.

Summary:
To address the accessibility and sustainability challenges of urban logistics it is important to consider urban logistics from a number of perspectives. This includes considering: spatial context i.e. not focusing solely on the urban center or core but also in terms of actions taken in broader logistics and supply chain management. stakeholders i.e. including all key decision makers and constituents.

Summary:
The central research question for this project explores the distributional impacts of ecommerce and its implications for equity and justice. The research aims to investigate how commercial land use affects people and communities. In 2018, U.S. warehouses surpassed office buildings as the primary form of commercial and industrial land use, now accounting for 18 billion square feet of floor space.
