Summary:
There are established relationships between urban form and passenger travel, but less is known about urban form and goods movement. The work presented in this paper evaluates how the design of a delivery service and the urban form in which it operates affects its performance, as measured by vehicle miles traveled, CO2, NOx, and PM10 emissions.

Summary:
The meteoric rise in urban deliveries and the lingering societal effects of the Covid-19 pandemic are having dramatic implications for the future of business, climate, and cities. Together with our collaborators and subject matter experts from across the logistics landscape, we are creating a collective vision for the urban freight system in 2030 and we are excited to present it in a new blog.

Summary:
Competition throughout the urban freight supply chain is steadily growing. Companies need to devise innovative methods for the transportation of goods from raw materials all the way to the final consumer. From concept to practice, it can be challenging to identify affordable solutions.

Summary:
This Toolkit is designed to help transportation professionals and researchers gather key data needed to make the Final 50 Feet segment function as efficiently as possible, reducing both the time trucks park in load/unload spaces and the number of failed first delivery attempts.

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:
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:
Public transportation could be an important component of a solution to providing mobility while reducing traffic congestion and the environmental impact of transportation. However, from a customer perspective, a mobility choice is only a choice if it is fast, comfortable and reliable. This research looks at the reliability of public transportation and the use of easy-to-access information to combat the inherent unreliability and other barriers to increased use that exist in the system.

Summary:
This article considers the effectiveness of a truck appointment system in improving yard efficiency in a container terminal. This research uses the truck appointment information obtained from an appointment system to improve import container retrieval operation and reduce container rehandles by adopting an advanced container location assignment algorithm. By reducing container rehandles, the terminal could improve yard crane productivity and reduce truck transaction time.

Summary:
Global positioning systems (GPS) used for fleet management by trucking companies provide probe data that can support a truck performance-monitoring program. This paper discusses the steps taken to acquire fleet management data and then process those data so they can eventually be used for a network-based truck performance measures program.

Summary:
This paper describes the development of a systematic methodology for identifying and ranking bottlenecks using probe data collected by commercial global positioning system fleet management devices mounted on trucks. These data are processed in a geographic information system and assigned to a roadway network to provide performance measures for individual segments.

Summary:
The economic viability and well-being of Washington State is significantly influenced by the freight transportation system serving the region.

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:
Common-carrier parcel lockers present a solution for decreasing delivery times, traffic congestion, and emissions in dense urban areas through consolidation of deliveries. Multi-story residential buildings with large numbers of residents, and thus a high volume of online package orders, are one of the best venues for installing parcel lockers. But what is the right size for a residential building locker that would suit the residents’ and building managers’ needs?
