Summary:
Two converging trends – the rise of e‐commerce and urban population growth – challenge cities facing competing uses for road, curb and alley space. The University of Washington has formed a living Urban Freight Lab to solve city logistics problems that cross private and public sector boundaries.

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:
The rapid expansion of ecommerce has flooded American cities with delivery trucks, just as those cities are experiencing booming population growth. Retailers need a more efficient, reliable, and cost-effective way to deliver goods in increasingly crowded urban environments. For their part, cities like Seattle want to minimize traffic congestion, both sustain quality of life for residents and ensure a smooth flow of goods and services.

Summary:
E-commerce has empowered consumers to order goods online from anywhere in the world with just a couple of clicks. This new trend has led to significant growth in the number of package deliveries related to online shopping. Seattle’s freight infrastructure is challenged to accommodate this freight growth. Commercial vehicles can already be seen double parked or parked illegally on the city’s streets impacting traffic flow and inconveniencing other road users.

Summary:
In recent years the focus on and prioritization of the notion of local food, food access and sustainability has been increasing throughout the U.S., especially in urban areas. The rising demand and growing preference for local produce in turn leads to changes in how we transport food. The supply chains found in urban areas are already complicated and costly, and as demand changes this poses a challenge if the local food movement is to be accommodated in our cities. A...

Summary:
Efficient and reliable goods movement via our nation’s highway system is critical to the nation’s economy and quality of life. Truck mobility is one of the key performance measures for evaluating the conditions of goods movement and supporting freight planning. Truck GPS data can be useful in developing truck mobility measures and providing insights into freight planning.

Summary:
Worldwide, awareness has been raised about the dangers of growing greenhouse gas emissions. In the United States, transportation is a key contributor to greenhouse gas emissions. American and European researchers have identified a potential to reduce greenhouse gas emissions by replacing passenger vehicle travel with delivery service.

Summary:
The Port of Seattle surveyed drayage truckers serving the port in 2006, 2008, and surveyed drivers again in 2013 in partnership with the University of Washington. This thesis describes the methodology used to survey drayage drivers at the Port of Seattle, describes the economic conditions of drayage drivers at the port and changes in economic conditions since previous surveys, and attempts to model driver earnings based on other driver characteristics.

Summary:
The effective and efficient movement of freight is essential to the economic well-being of our country but freight transport also adversely impacts our society by contributing to a large number of crashes, including those resulting in injuries and fatalities.

Summary:
Container terminals are important intermodal interfaces between marine and land transport networks. These interfaces have historically been sources of congestion and logistical inefficiencies. Exacerbated by growing trade volumes, the terminals have become bottlenecks in the port-related supply chain. This research explores using truck arrival information to integrate drayage truck and container terminal operations and improve intermodal system efficiency.

Summary:
As commercial vehicle activity grows, the environmental impacts of these movements have increasing negative effects, particularly in urban areas. The transportation sector is the largest producer of CO2 emissions in the United States, by end-use sector, accounting for 32% of CO2 emissions from fossil fuel combustion in 2008.

Summary:
Activities of commercial vehicles just prior to or just following international border crossings are not well understood. Logistical responses to border crossings are believed to increase empty miles traveled, travel times and total vehicle emissions.

Summary:
Growing pressure to limit greenhouse gas emissions is changing the way businesses operate. A model was developed in ArcGIS to evaluate the trade-offs between cost, service quality (represented by time window guarantees), and emissions of urban pickup and delivery systems under these changing pressures. A specific case study involving a real fleet with specific operational characteristics is modeled as an emissions minimization vehicle routing problem with time windows (EVRPTW).

Summary:
Intra-industry trade (IIT) occurs when trading partners import and export similar products. A high volume of IIT of horizontally differentiated goods implies a deep level of regional integration, stable regional trading patterns, and potentially significant consequences from border delay. In this paper, trade between Washington State and British Columbia, Canada (the Cascade gateway), is compared with trade between Michigan State and Ontario, Canada (the Great Lakes gateway).
