Leveraging a Connected Network of Unattended Micro-Pantries to Reduce Food Waste and Improve Food Security

Traditional Hunger Relief Organizations (HROs) play a central role in reducing food insecurity. However, they face increasing challenges in equitably distributing rescued food. Vulnerable populations, such as the elderly, physically disabled individuals, and households with children, are often not able to access HROs during limited opening hours. Moreover, HROs often do not rescue food from smaller businesses, such as cafes, restaurants, and households which contribute to 70 percent of food waste in urban areas. Instead, HROs rely mostly on larger supply chains, not directly reducing food waste at a neighborhood level. This project proposes to pilot a decentralized network of connected, unattended food micro-pantries to provide real-time information on existing demand for rescued food to food donors, collect food donations at a micro-scale level across neighborhoods of the Seattle study area, and monitor food safety. Micro-pantries are an emerging community-driven concept of independent, small, unattended, open-access, and community-run food pantries and fridges that are hosted on public-right-of-way or private properties and maintained by community members and local organizations. The disaggregated network of micro-pantries could support HROs as additional, more accessible and resilient food sources available closer to vulnerable communities and support more localized food rescue from households and local businesses.

The research team will prototype a wireless sensor platform installed at selected micro-pantries to collect food donations and pick-up data and provide real-time information to community groups, HROs, and local businesses to optimize the distribution of rescued food. The project is the first empirical study to quantitatively analyze micro-pantries’ role in fighting food insecurity and improving equitable access to healthy eating. The research team will (1) perform a geospatial analysis of the existing network of micro-pantries in Seattle, WA; (2) develop and test a novel low-cost sensing system to detect food donations and pick-ups and measure food conditions; (3) develop a food donation training protocol for households and businesses located in proximity to micro-pantries; (4) estimate empirical demand and supply models to distribute rescued food optimally; (5) perform community outreach to document current food waste and food rescue practices. This research will provide a valuable, first-of-its-kind formal study of micro-pantries as a potential solution to food security that seeks to close gaps in traditional food rescue distribution. The results will provide key data to scale up programs that benefit low-income, food-insecure individuals, establishing a proof of concept for new community-based food distribution methods. The team includes experts from the University of Washington on urban distribution systems, sensor systems, and food safety, as well as a community partner working with local HROs to support food rescue and distribution.

This project is in response to the Civic Innovation Challenge program’s Track B. Bridging the gap between essential resources and services & community needs and is a collaboration between NSF, the Department of Homeland Security, and the Department of Energy.

Freight and Bus Lane (FAB) Data Collection and Evaluation Plan (Route 40)

The Urban Freight Lab (UFL) was approached by the Seattle Department of Transportation (SDOT) to complete a review of proposed evaluation criteria and propose a data collection plan in preparation for the implementation of a Freight and Bus Lane (FAB) Lane in Fall 2024 for King County Metro’s Bus Route 40.

This project would effectively produce the follow-on scope of work for the UFL to complete during the actual implementation (pre/post/post phase). UFL will build on the findings from the Urban Freight Lab’s Freight and Transit Lane Case Study completed in 2019. With the completion of the Route 40 TPMC project in Fall 2024, FAB lanes will be tested as a pilot in select locations and evaluated before permanent installation.

Objectives

  • Refresh literature review on freight and transit lane studies
  • Meet with key stakeholders from SDOT and Metro to understand data collection tools and methodologies
  • Propose a technical evaluation plan for this pilot that includes data collection and metrics and communication strategies

Success Factors for Urban Logistics Pilot Studies

Publication: The Routledge Handbook of Urban Logistics
Publication Date: 2023
Summary:

The last mile of delivery is undergoing major changes, experiencing new demand and new challenges. The rise in urban deliveries amid the societal impacts of the COVID-19 pandemic has dramatically affected urban logistics. The level of understanding is increasing as cities and companies pilot strategies that pave the way for efficient urban freight practices. Parcel lockers, for instance, have been shown to reduce delivery dwell times with such success that Denmark increased its pilot program of 2,000 lockers to 10,000 over the past two years. This chapter focuses on challenges faced during those pilots from technical, managerial and operational perspectives, and offers examples and lessons learned for those who are planning to design and/or run future pilot tests. On-site management proved to be critical for locker operations.

Analysis of a Food Bank Home Delivery Program

Food security, defined as access at all times to nutritious food, is a necessary condition for human beings to thrive and have an active and healthy life. In Seattle, about 13 percent of adults experienced food insecurity. Moreover, food security is not equitably distributed across the population. Food insecurity is more common in households with young children, with single parents, with incomes below 185 percent of the poverty threshold, in Black and Hispanic populations, and in principal metropolitan areas. Hunger relief organizations, such as food banks, play a key role in redistributing food to those experiencing food insecurity. However, a share of the food-insecure population could not be reached by this system. In particular, people who are immobile, immunocompromised, and elderly are not able to access the food bank network. The University District Food Bank, serving the northeast neighborhoods of Seattle, started a home delivery program 10 years ago, where volunteers pick up groceries at the food bank and deliver them to households in need, and largely expanded it during the pandemic. While volunteers were initially performing deliveries using cars or vans, the program was expanded through a collaboration with the Cascade Bicycle Club, a non-profit bike advocacy organization.

For this work, the project team proposes a collaboration between young junior scholars at the Urban Freight Lab (UFL) with expertise in the study of last-mile urban distribution systems, the University District Food Bank, and the Cascade Bicycle Club. This grant will enable UFL researchers to perform preliminary research, to better understand the challenges in the last-mile distribution of food from food banks and identify operational improvements to increase the efficiency of the system.

Paper

Evacuating Isolated Islands with Marine Resources: A Bowen Island Case Study

 
Download PDF  (9.41 MB)
Publication: International Journal of Disaster Risk Reduction
Volume: 72
Publication Date: 2022
Summary:

Inhabited islands are susceptible to natural hazards, such as wildfires. To avoid disasters, preventative measures and guidelines need to be in place to strengthen community resilience. If these fail, evacuation is often the only choice. However, island evacuation is a vastly understudied problem in both research and practice, particularly for islands without permanent road connections to the mainland that require marine evacuation. Multiple vessel trips are necessary to evacuate the population from suitable access points, which previous studies did not entertain. Furthermore, most existing studies either focus on evacuations from an academic, or from a government perspective. Instead, this paper presents a collaborative approach. It applies a recently developed evacuation routing model that optimizes the evacuation plan for Bowen Island in Canada through minimizing the expected evacuation time across disaster scenarios. These were designed with the participation of a broad range of stakeholders, from local residents and volunteer groups to agencies from all levels of government and companies, which integrates both academic and practical perspectives to maximize solution quality. Different options for fleet sizes, staging locations and scenarios were considered. The results show that the optimized evacuation time for Bowen Island varies between 1 and 8 h, as it strongly depends on the disaster scenario, the evacuation fleet, and can be accelerated by temporary staging areas. The suitability of the approach for evacuation studies can be confirmed through the identification of key improvements for increased community resilience and the inclusion of the results in the official Bowen Island evacuation plan.

Biking the Goods: How North American Cities Can Prepare for and Promote Large-Scale Adoption

With the rise in demand for home deliveries and the boom of the e-bike market in the U.S., cargo cycles are becoming the alternative mode of transporting goods in urban areas. However, many U.S. cities are struggling to decide how to safely integrate this new mode of transportation into the pre-existing urban environment.

In response, the Urban Freight Lab is developing a white paper on how cities can prepare for and promote large-scale adoption of cargo cycle transportation. Sponsors include freight logistics providers, bicycle industry leaders, and agencies Bosch eBike Systems, Fleet Cycles, Gazelle USA, Michelin North America, Inc., Net Zero Logistics, the Seattle Department of Transportation, and Urban Arrow.

The Urban Freight Lab is internationally recognized as a leader in urban freight research, housing a unique and innovative workgroup of private and public stakeholders and academic researchers working together to study and solve urban freight challenges. The Urban Freight Lab has previously worked on evaluating, studying, and deploying cargo cycles in Asia and the U.S, and is recognized as an expert leader in North America on cargo cycle research.

Objectives
The objectives of the white paper are the following:

  1. Define and understand what types of cargo bikes exist in North America, their main features, how they are operated, and the infrastructure they need.
  2. Identify opportunities for and challenges to large-scale adoption of cargo cycles in North American cities.
  3. Learn from case studies of U.S. cities’ approaches to regulating and promoting cargo cycles.
  4. Provide recommendations for how cities can safely recognize, enable and encourage large-scale adoption of cargo bikes, including infrastructure, policy, and regulatory approaches.

The Seattle Neighborhood Delivery Hub Pilot Project: An Evaluation of the Operational Impacts of a Neighborhood Delivery Hub Model on Last-Mile Delivery

 
Download PDF  (2.98 MB)
Publication Date: 2021
Summary:

As one of the nation’s first zero-emissions last-mile delivery pilots, the Seattle Neighborhood Delivery Hub served as a testbed for innovative sustainable urban logistics strategies on the ground in Seattle’s dense Uptown neighborhood. Providers could test and evaluate new technologies, vehicles, and delivery models — all in service of quickly getting to market new more fuel- and resource-efficient solutions, reducing emissions and congestion, and making our cities more livable and sustainable.

These technologies are also an important part of the City of Seattle’s Transportation Electrification Blueprint, including the goal of transitioning 30% of goods delivery to zero emissions by 2030.

Biking for Goods: A Case Study on the Seattle Pedaling Relief Project

1. Introduction
One of the disruptions brought by the COVID-19 pandemic was the reduction of in-store shopping, and the consequent increase in online shopping and home deliveries. However, not everyone had equal access to online shopping and home-delivery services. Customers relying on food banks were forced to shop in-store even during the pandemic. In 2020, the Cascade Bicycle Club started the Pedaling Relief Project (PRP) – a not-for-profit home delivery service run by volunteers using bikes to pick up food at food banks and deliver to food bank customers, among other services.

The Urban Freight Lab collaborates with the Cascade Bicycle Club (CBC) to study and improve PRP operations. For this work, students in Prof. Anne Goodchild’s Transportation Engineering course on Transportation Logistics (CET 587) are undertaking a case study: to analyze the transport and logistics system of the Pedaling Relief Project and provide recommendations for how to improve operations.

2. Background
2.1. Food rescue at a glance
An estimated 94,500 tons of food from Seattle business establishments end up in compost and landfills each year, while many members of our community remain food insecure. The process of food rescuing consists of the gleaning of edible food from business establishments – called donor businesses such as grocery stores, restaurants, and commissary kitchens – that otherwise would enter the waste stream and be re-distributed to local food programs. Hunger relief agencies, also referred to as food banks, are non-profit organizations that collect rescued food, either directly from businesses or through food rescue distributors (such as Food Lifeline or Northeast Harvest) and re-distribute it to the community through meal programs, walk-ins, and pop-up food pantries, student backpack programs, among others.

Read more about the Seattle food rescue system in SCTL’s report (2020) on “Improving Food Rescue in Seattle: What Can Be Learned from a Supply Chain View?

2.2. Pedaling Relief Project
In 2020 the Cascade Bicycle Club started the Pedaling Relief Project (PRP), a volunteer-based program that collaborates with local food banks to offer three main types of services — (1) grocery delivery, (2) food rescue, (3) little free pantry restocking — coordinating a network of volunteers on bikes.

  1. Grocery delivery (GD) service consists of picking up grocery bags from food banks and performing delivery routes, distributing food to food bank customers that asked for home delivery services.
  2. Food rescue (FR) services support the existing distributors by picking up food at business establishments and carrying rescued food to local food banks.
  3. Little free pantries restocking (LFPR) services consist of picking up food at local food banks and carrying it to neighborhood micro pantries –containers placed on local streets and open to everyone to store food from donors to whoever needs it. Learn more about the Little free pantries project on thelittlefreepantries.org.

Volunteers use their own bikes, with some cargo carry capacity, or can request a bike trailer or cargo bike from the Cascade Bicycle Club.

2.3. Cargo Bikes
Cargo bikes are two/three/four-wheel bikes with some cargo-carrying capacity. They are increasingly used as an alternative mode to trucks and vans to transport goods in urban areas. Cargo bikes are often supported by an electric motor that assists the driver when pedaling. Compared to internal combustion engine vehicles, cargo bikes do not produce tailpipe emissions and they consume less energy than electric vans (Verlinghieri et al., 2021). They also offer several operational advantages: they are more agile in navigating urban road traffic, they can use alternative road infrastructure such as bike lanes and sidewalks to drive and park, they can park closer to their delivery destination, reducing walking distances and parking dwell times (Dalla Chiara et al., 2020).

3. Project instructions

The CBC provided access to anonymous data on the PRP operations for the exclusive use of the 2022 CET 587 course student cohort final projects. Students are asked to individually perform empirical research using the provided data and/or self-collected data on the PRP operations with the following objectives:

  • Empirically analyze and describe PRP operations.
  • Provide recommendations on what actions can be taken to improve PRP operations.

Projects will meet the following two requirements:

  • Use the provided data and/or self-collected and/or publicly sourced data to perform empirical analysis
  • Provide justified and concrete recommendations on how to improve the PRP.
  • Complete deliverables 1 and 2 (see below), which consist of 2 presentations, a project proposal, and a final project report.

Project progress timeline and deliverables:

Weeks Progress & Deliverables
1-2 Become familiar with R language programming; PRP background and data
3 CBC gives a guest lecture about PRP
4-5 Project proposal; 2-minute lightning talk about the project proposal
Deliverable 1: 1-page project proposal
6-10 Implement proposed methodology and perform research
11 Each student will give a 15-minute presentation of the main results of the project
Deliverable 2: Final report
The following are potential project directions:
  • Analyze current routes performed by volunteers. How can they be improved? Get the work done more quickly, or with fewer bikes?
  • Analyze data from little free pantries restocking. Collect additional data on the use of Little Free Pantries by manual observations or by installing sensors in a few of them. Can we model demand and supply for food donations?
  • Collect and analyze GPS data by signing up and performing some of the PRP routes yourself. What type of infrastructure do cargo bikes need and how does street and curb use behavior differ between cargo bikes and vans? What can the city do to better support this type of activity?
  • Analyze volunteers’ behaviors data. Is it possible to model the supply of volunteers? Can you simulate different scenarios of volunteer supply?
  • Develop your own direction with approval.

Students will be provided with a base dataset on PRP operations. Students are encouraged to use other datasets self-collected or from public data sources (e.g. check out the SDOT Open Data Portal), to share ideas in class and among each other, to use as much as possible class time, guest lectures and office hours to ask questions and share ideas.

1: 1-page project proposal and 2-minute lightning talk describing motivation, project objective(s) and research question(s), proposed methodology (data to use/collect, methods to implement), and expected results.

2: Final report and 10-minute presentation describing data used, including sample size and sample statistics, how data collection was performed, empirical analysis performed using data and results from the analysis, and conclusions, key findings, and key recommendations.
