Cost, Emissions, and Customer Service Trade-Off Analysis In Pickup and Delivery Systems

Publication: Oregon Department of Transportation, Research Section
Publication Date: 2011
Summary:

This research offers a novel formulation for including emissions into fleet assignment and vehicle routing and for the trade-offs faced by fleet operators between cost, emissions, and service quality. This approach enables evaluation of the impact of a variety of internal changes (e.g. time window schemes) and external policies (e.g. spatial restrictions), and enables comparisons of the relative impacts on fleet emissions. To apply the above approach to real fleets, three different case studies were developed. Each of these cases has significant differences in their fleet composition, customers’ requirements, and operational features that provide this research with the opportunity to explore different scenarios.

The research includes estimations of the impact on cost and CO2 and NOX emissions from fleet upgrades, the impact on cost, emissions, and customer wait time when demand density or location changes, and the impact on cost, emissions, and customer wait time from congestion and time window flexibility. Additionally, it shows that any infrastructure use restriction increases cost and emissions. A discussion of the implications for policymakers and fleet operators in a variety of physical and transportation environments is also presented.

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. This article highlights recent research conducted by the University of Washington’s Urban Freight Lab and its partners to explore new methods to reduce transportation costs, improve the customer experience, reduce carbon footprint, and reduce urban congestion after goods leave the shipping docks.

Characterizing Washington State’s Supply Chains

Publication: Transportation Northwest Regional Center X (TransNow)
Publication Date: 2012
Summary:

The University of Washington (UW), Washington State University (WSU), and Washington State Department of Transportation (WSDOT) recently developed a multi-modal statewide geographic information system (GIS) model that can help the state prioritize strategies that protect industries most vulnerable to disruptions, supporting economic activity in the state and increasing economic resilience. The proposed research was identified after that project as an important step in improving the model’s ability to measure the impact of disruptions. In addition to developing the model, the researchers developed two case studies showing the model’s capabilities: the potato growing and processing industry was chosen as a representative agricultural sector and diesel fuel distribution for its importance to all industry sectors. As origin-destination data for other freight-dependent sectors is added to the model, WSDOT will be able to evaluate the impact of freight system disruptions on each of them. Moving forward, it is not cost-effective to develop case studies in the manner used for these case studies, therefore, the state is currently supporting activities at the national level that will provide methods for collecting statewide commodity flow data. However, this commodity flow data will still lack important operational detail necessary to understand the impacts of transportation changes. This research will begin to fill that gap by developing a transportation-based categorization of logistics chains. The goal is not to capture all of the complexity of supply chain logistics but to identify approximately 15-20 categories within which supply chains behave similarly from a transportation perspective, for example, in their level of scheduling and methods for route selection. Researchers will use existing publicly available data, conduct an operational survey, and analyze GPS data collected for WSDOT’s freight performance measures project to identify the categorization.

She is Professor of Civil and Environmental Engineering and Founder of both the Supply Chain Transportation & Logistics online Master’s degree program and the Urban Freight Lab (UFL).

Under Goodchild’s leadership, the UFL coined the increasingly used term “Final 50 Feet” and defined it as the last leg of the supply chain for urban deliveries—including finding parking, moving items from a delivery vehicle, navigating traffic, sidewalks, intersections, bike lanes, and building security, and ending with the recipient. In addition to being key to customer satisfaction, this final segment is both the most expensive (where an estimated 25-50% of total supply chain costs are incurred) and most time-consuming part of the delivery process—and ripe for improvement. One of the hurdles in the final 50 feet is that many different parties are involved—city departments of transportation, delivery carriers, property owners, residents, and consumers—making a collaborative effort between sectors essential for developing mutually beneficial solutions. Using a systems engineering approach, the UFL has completed innovative research projects that provide foundational data and proven strategies, such as:

Publication Date: 2021
Summary:
In recent years, e-commerce has dramatically increased deliveries to residential areas. The rise in delivery vehicle activity creates externalities for the transportation system, including congestion, competition for parking space, and emissions. Common carrier lockers have emerged as a way to manage these effects by consolidating deliveries, but they remain largely untested in the United States. This thesis examines the effects of a common carrier locker placed in a residential building in downtown Seattle, Washington. An experimental design with on-street data tests the effect of the locker on dwell times and time that delivery people spend in the building. Data collected by the locker provider gives insight into the e-commerce behavior patterns of residents. Finally, a simulation model was constructed to obtain the optimal configuration of box sizes in similar lockers. The results show that the locker had a statistically significant effect on time spent within the building, but not on dwell times or curb productivity. However, dwell times for similar vehicles in this sample decreased somewhat. The simulation demonstrated that time-based policies and flexible locker designs can prove to be effective strategies for managing demand.

Summary:

In many regions throughout the world, freight models are used to aid infrastructure investment and policy decisions. Since freight is such an integral part of efficient supply chains, more realistic transportation models can be of greater assistance. Transportation models in general have been moving away from the traditional four-step model into activity-based and supply chain-based models. Personal transportation models take into consideration household demographics and why families travel. Freight research has yet to fully identify the relationships between truck movements and company characteristics, so most freight models use the methodology of personal transportation models, despite situational differences.

In an effort to classify freight companies into groupings with differentiated travel movements, a survey of licensed motor carriers was designed and conducted in Oregon. The survey consisted of 33 questions. Respondents were asked about their vehicle fleets, locations served, times traveled, types of deliveries, and commodities. An analysis of the data revealed clusters of company types that can be distinguished by determining characteristics such as their role in a supply chain, facilities operated, commodity type, and vehicle types. An assessment of how the relationships found can be integrated into state models is also presented.

SimMobility Freight: An Agent-Based Urban Freight Simulator for Evaluating Logistics Solutions

Publication: Transportation Research Part E: Logistics and Transportation Review
Volume: 141
Publication Date: 2020
Summary:

Despite significant advances in freight transport modeling in recent years, there is still lack of available tools for evaluating novel logistics solutions. We introduce the framework of SimMobility Freight, which is part of SimMobility, a multi-scale agent-based urban transportation simulation platform. SimMobility Freight is capable of simulating commodity contracts, logistics and vehicle operation planning and parking decisions in a fully-disaggregate manner. This allows us to evaluate alternative logistics solutions and measure their impacts. To illustrate its capability, we conduct an analysis of delivery time window regulations, assessing the policy impacts.

An Evaluation of Logistics Sprawl in Chicago and Phoenix

 
Download PDF  (2.28 MB)
Publication: Journal of Transport Geography
Volume: 88
Publication Date: 2018
Summary:

This paper evaluates whether or not there is a sprawling tendency to the spatial patterns of warehouse establishments in the Chicago and Phoenix metropolitan areas. The trend of warehouses to move away from the urban centers to more suburban and exurban areas is referred to as “Logistics Sprawl”. To measure sprawl, the barycenter of warehousing establishments was compared to the barycenter of all other industry establishments in the region between the years of 1998 and 2013 for Chicago; 1998 and 2015 for Phoenix. This shows that logistics sprawl is a behavior experienced by warehouses in the Chicago area, but not in the Phoenix area. This paper discusses if logistics sprawl is a national trend or a regional behavior by comparing these results to the previous case studies of the Atlanta, Los Angeles, and Seattle metropolitan areas.

Roadblocks to Sustainable Urban Freight

While freight transportation is a necessary activity to sustain cities’ social and economic life, enabling the movement and deployment of goods and services in and between urbanized areas, it also accounts for a significant portion of greenhouse gas (GHG) emissions, and therefore it is a major contributor to climate change. Guaranteeing an efficient and sustainable urban freight transport ecosystem is necessary for cities to survive and tackle the climate emergency.
Several stakeholders in the private and public sectors are currently taking action and drafting roadmaps to achieve such goals. However, as the urban freight ecosystem is a complex network of stakeholders, achieving such sustainability goals requires collaboration and coordination between multiple agents.
The project will collect and synthesize expert views from both the private and public sectors on what is needed to sustainably deliver the last mile and aims at identifying the roadblocks towards this goal. All types of goods and services will be considered, with the end goal of raising the entire industry’s understanding of the barriers to achieving sustainable urban freight.

Approach

Task 1: Research Scan (September-November 2020) Subtasks:

  1. identify an accepted and shared definition of sustainable urban freight;
  2. identify and classify the main agents of the urban freight system from both the private and public sectors and their main role in the last-mile ecosystem;
  3. identify and classify the main accepted strategies currently adopted towards sustainability.
The research team will also define the boundaries of the study, including the geographical region of concentration.

Task 2: Private sector expert interviews (December 2020-April 2021)

The main private sector agents identified in Task 1 will include vehicle manufacturers, retailers, carriers and more. The research team will identify and reach out to representatives of at least 15 companies. Participants will be interviewed using an open question format and will have an optional follow-up online survey. The objectives of the interviews and surveys are:
  1. listing the current strategies adopted to reach sustainable urban freight;
  2. understanding what the impacts are of other private and public sectors agents’ decisions on their sustainability strategies;
  3. identifying agents’ needs and obstacles to achieve their stated sustainable goals.

Task 3: Public sector expert interviews (December 2020-April 2021)

The research team will identify different urban typologies, classifying cities into homogeneous groups according to economic, demographic, urban form, mobility and sustainability indicators. The typologies will be used to sample cities from each identified urban typology.
The team will then reach out to representatives from the public sector agents from the sampled cities, including regulators, planners and public utility representatives, and perform a combination of online survey and online/phone interviews. At least 15 representatives from public sector agents will be contacted. The objectives of the interviews are:
  1. listing the current policies adopted by cities towards sustainable urban freight, including infrastructure investments and transport demand management;
  2. understanding what the obstacles are to achieve sustainability goals.

Task 4: Synthesizing research and identifying roadblocks (May-June 2021)

Synthesizing the work of the previous 3 tasks, and applying the research team’s own expertise, this task will identify the key obstacles to sustainable urban freight. Through a review of existing writings, discussions with experts, and their own domain expertise, the research team will identify the obstacles in the areas of transportation technology, infrastructure, and policy. This review will consider the obstacles in public sector, barriers to private business decision making, and where the two sectors need to take a collaborative approach. The results obtained in the study will be made available publicly as a white paper or submitted for scientific journal publication.
