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:
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:
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:
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:
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:
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:
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:
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:
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 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:
The Norwegian Public Roads Administration, the Norwegian Geotechnical Institute, and SINTEF conducted a field test with a unmanned aerial system (UAS) with various instruments at the research station Fonnbu in Stryn. The purpose of the test was to evaluate the use of instrumented drones for monitoring and assessing avalanche danger. The instruments tested included optical and thermal imaging, laser scanning and ground-penetrating radar.

Summary:
The rapid rise of on-demand transportation and e-commerce goods deliveries, as well as increased cycling rates and transit use, are increasing demand for curb space. This demand has resulted in competition among modes, failed goods deliveries, roadway and curbside congestion, and illegal parking. This research increases our understanding of existing curb usage and provides new solutions to officials, planners, and engineers responsible for managing this scarce resource in the future.

Summary:
Moving freight is vital to our ability to live in cities and access goods — but who bears the costs of moving goods, and who benefits from the access that goods movement provides? These costs and benefits have not been borne equally. The last blog post revealed how urban freight is largely missing in discussions around transportation equity and accessibility. Freight delivers immense benefits to cities and residents.

Summary:
This paper presents a method for extracting transit performance metrics from a General Transit Feed Specification’s Real-Time (GTFS-RT) component and aggregating them to roadway segments. A framework is then used to analyze this data in terms of consistent, predictable delays (systematic delays) and random variation on a segment-by-segment basis (stochastic delays). All methods and datasets used are generalizable to transit systems which report vehicle locations in terms of GTFS-RT parameters.
