Summary:
What does an equitable and just freight system actually look like? We asked UFL members this question at the summer 2022 quarterly meeting. Their responses, shown in the graphic below, cover a wide range of ideas and topics. Some define equity in terms of equal access to the numerous benefits a freight system brings; others call for a reduction in freight costs — like pollution, noise, and traffic — to historically marginalized people. Members differ on who the appropriate stakeholders...

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:
Pickup and delivery operations are an essential part of urban goods movements. However, rapid urban growth, increasing demand, and higher customer expectations have amplified the challenges of urban freight movement. In recent years, the industry has emphasized improving last-mile operations with the intent of focusing on what has been described as the last leg of the supply chain.

Summary:
At the time we are writing this article, hundreds of thousands of delivery vehicles are getting ready to hit the road and travel across U.S. cities to meet the highest peak of demand for ecommerce deliveries during Thanksgiving, Black Friday, and the Christmas holiday season. This mammoth fleet will not only add vehicle miles traveled through urban centers but also increase parking congestion, battling with other vehicles for available curb space.

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:
Roadway tolls are designed to raise revenue to fund transportation investments and manage travel demand and as such may affect transportation system performance and route choice. Yet, limited research has quantified the impact of tolling on truck speed and route choice because of the lack of truck-specific movement data.

Summary:
This paper presents a systematic methodology for identifying and ranking bottlenecks using probe data collected by commercial GPS fleet management devices. This methodology is based on the hypotheses that truck speed distributions can be represented by either a unimodal or bimodal probability density function, and it proposes a new reliability measure for evaluating roadway performance.

Summary:
The Washington State Department of Transportation (WSDOT), Transportation Northwest at the University of Washington (UW), and the Washington Trucking Associations (WTA) have partnered on a research effort to collect and analyze global positioning systems (GPS) truck data from commercial, invehicle, truck fleet management systems. This effort was funded by the Washington State Legislature, and its purpose is to develop a statewide freight performance measures program for use by WSDOT.

Summary:
There is not enough curb capacity, now. A recent curb parking utilization study in the City of Seattle indicated 90% or higher occupancy rates in Commercial Vehicle Load Zones (CVLZs) for some areas for much of the workday. The Final Fifty Feet is a new research field. The Final 50 Feet project is the first time that researchers have analyzed both the street network and cities’ vertical space as one unified goods delivery system. It focuses on: The use of...

Summary:
A 20% e-commerce compound annual growth rate (CAGR) would more than double goods deliveries in 5 years. If nothing changes, this could double delivery trips in cities; thereby doubling the demand for load/unload spaces. Innovation is needed to manage scarce curbs, alleys, and private loading bay space in the new world of on-demand transportation, 1-hour e-commerce deliveries, and coming autonomous vehicle technologies.

Summary:
This report provides a guidebook for conducting benefit-cost analyses of proposed infrastructure investments on multimodal, multi-jurisdictional freight corridors for public and private decision-makers and other stakeholders at local, state, regional, and national levels to arrive at more informed investment decisions.

Summary:
The demand for truck transportation increases alongside growth in population and economic activity. As both truck and passenger traffic outstrip roadway capacity, the result is congestion, which the freight community experiences as truck bottlenecks. This NCHRP project produced a Guidebook that provides state-of-the-practice information to transportation professionals on practices and measures for identifying, classifying, evaluating, and mitigating truck freight bottlenecks.

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:
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.
