Summary:
Urban Freight Lab’s foundational report is the first assessment in any American city of the privately-owned and operated elements of the Final 50 Feet of goods delivery supply chains (the end of the supply chain, where delivery drivers must locate both parking and end customers). These include curb parking spaces, private truck freight bays and loading docks, street design, traffic control, and delivery policies and operations within buildings.

Summary:
This report provides compelling evidence of the effectiveness of a new urban goods delivery system strategy: Common Carrier Locker Systems that create parcel delivery density and provide secure delivery locations in public spaces.

Summary:
This report describes the Urban Freight Lab (UFL) work to map the locations of all private loading docks, loading bays, and loading areas for commercial vehicles in Seattle’s First Hill and Capitol Hill neighborhoods and document their key design and capacity features, as part of our Final 50 Feet Research Program.

Summary:
This report presents a pilot test of a common carrier smart locker system — a promising strategy to reduce truck trip and failed first delivery attempts in urban buildings. The Urban Freight Lab tested this system in the 62-story Seattle Municipal Tower skyscraper in downtown Seattle.

Summary:
Vehicles of all kinds compete for parking space along the curb in Seattle’s Greater Downtown area. The Seattle Department of Transportation (SDOT) manages use of the curb through several types of curb designations that regulate who can park in a space and for how long.

Summary:
More than 80 percent of Americans have purchased goods online and, in 2016, more than 8 percent of all retail sales in the U.S. took place online. The growth of ecommerce is putting increasing pressure on local governments to rethink how they manage street curb parking and alley operations for trucks and other delivery vehicles. It is also forcing building developers and managers to plan for the influx of online goods. To develop practical solutions to these problems, in 2016...

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:
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:
With growing freight operations within the United States, there continues to be a push for urban streets 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 can obstruct roadway infrastructure designated to vulnerable road users (e.g., pedestrians and cyclists).

Summary:
This paper uses simulation to evaluate the use of truck arrival information to reduce container rehandles during the import container retrieval process by improving terminal operations. A variety of scenarios with different levels of truck information and various container bay configurations are modeled to explore how the information quality and bay configuration affect the magnitude of benefit.

Summary:
This paper quantifies the benefits to drayage trucks and container terminals from a data-sharing strategy designed to improve operations at the drayage truck-container terminal interface. This paper proposes a simple rule for using truck information to reduce container rehandling work and suggests a method for evaluating yard crane productivity and truck transaction time.

Summary:
A factor that influences transit ridership but has not received much attention from researchers is weather. This paper examines the effects of weather on bus ridership in Pierce County, Washington, for the years 2006–2008. Separate ordinary least squares regression models were estimated for each season, as weather conditions may have different effects depending on the time of year. Four weather variables were considered: wind, temperature, rain, and snow.

Summary:
As awareness of the vulnerability of isolated regions to natural disasters grows, the demand for efficient evacuation plans is increasing. However, isolated areas, such as islands, often have characteristics that make conventional methods, such as evacuation by private vehicle, impractical to infeasible. Mathematical models are conventional tools for evacuation planning.

Summary:
This life cycle assessment case study puts the supply chain contribution of transportation to greenhouse gas emissions in context with other contributors using American wheat grain as a representative product. Multiple locations, species and routes to market are investigated.
