Joint Hearing on:
“Where’s My Stuff? Examining the Economic, Environmental, and Societal Impacts of Freight Transportation”
before the United States House Committee on Transportation and Infrastructure the Subcommittee on Highways and Transit and the Subcommittee on Railroads, Pipelines, and Hazardous Materials.
December 5, 2019
Good morning, Chairs Norton and Lipinski and Ranking Members Davis and Crawford as well as distinguished Members of the Committee. Thank you for the opportunity to speak to you about this important topic. My name is Anne Goodchild and I am a professor and the Director of the Supply Chain Transportation and Logistics Center at the University of Washington. I am an urban freight expert. The freight system, ultimately, allows for economic specialization; it supports city living, provides markets to producers, and strengthens competition. On its own, the transportation and logistics sector represents approximately 10% of the US gross domestic product – a larger sector than either retail, or financial services. The freight system is more than interstates, ports, pipelines and rail facilities. The freight system is city streets, local highways, sidewalks, bike lanes, and front steps – the last mile of where these supply chains is carried out. It is the delivery man walking to your door or mailbox. When we talk about freight infrastructure investment and building a better freight system, we must remember to include the last mile and particularly the Final Fifty Feet to the final delivery destination. Without completing this final step, supply chains fail to deliver the economic and social benefits they promise.
Last mile costs businesses a disproportionate amount of time and money
The last mile is essential, and expensive; the most difficult and costly mile of all. While estimates vary, the cost of the last mile has been estimated at between 25% and 50% of total supply chain transportation costs.
The last mile is costly because:
- It relies more on human labor than the other segments of supply chain transportation with drivers going door-to-door to drop off packages. In cities, drivers can spend 80 or 90% of their time outside the vehicle
- Goods are more fragmented the farther you travel down the supply chain. Upstream, goods are moved in large, consolidated shipments such as single commodities but the closer goods get to the consumer the more they are broken down into shipments for individual customers
- 80% of Americans live in congested regions where travel speeds are slower and less reliable. This increases the number of vehicles and drivers required to do the same work
- There can be high rates of failed deliveries requiring repeated delivery attempts and resulting in ballooning costs. Failed delivery attempts can mean that two or three additional trips are require to accomplish the same task.
While the high cost of the last mile is in part due to the distributed nature of deliveries, the cost is inflated by congestion, a lack of reasonable parking options, and other constraints put on commercial vehicle operations such as specific street or time of day bans.
Online shopping growing and speeding
Online shopping rates are growing and this is increasing demand for last mile delivery. UPS, the world’s largest package delivery company, experienced 23% revenue growth from 2014 to 2018 (5.5% annually ). With one-click shopping and free home delivery it is now often cheaper and easier to order something online than it is to go to the store. Retail e-commerce sales as a percent of total retail sales in United States rose to 9% in 2017 and this figure is expected to reach 12.4% in 2020. With store-based shopping, most Americans use their personal vehicles for shopping trips; driving to the store alone, purchasing a few items, and returning home in their car. With an online purchase, the trip – now a delivery – is made with a commercial vehicle, extending the supply chain from the store or warehouse and bringing increasing numbers of commercial vehicles into towns and neighborhoods. The volume of daily deliveries to homes has soared – from fewer than 360,000 a day in New York City in 2009 to more than 1.5 million today . Households now receive more deliveries than businesses; and this, with online retail representing only 10% of all retail. Imagine how many more trips there will be when online retail hits 20% or 50%.
In addition to growth in the number of deliveries, the pace of delivery of speeding. Amazon, which currently holds about a 50% share of the online market in the US has, in the last 3 years, halved their average click-to-door speed from about 6 days to about 3 days . Other retailers are attempting to keep pace. Just this week I received an email from Amazon notifying me that Amazon Fresh would now deliver at “ultrafast speeds” in my area: “You can schedule same-day deliveries from 6:00am – 10:00pm and get FREE 2-hour scheduled delivery windows on orders over $35”. Free two-hour delivery. This was not in response to a request, rather this is being rolled out to all Prime members. Depending on your location, you can also get 1-hour delivery for a small additional fee. This is also available in DC and Northern VA. There has also been a proliferation of on-demand delivery services, particularly in the food delivery sector, where online platforms now serve close to 30% of the market.
The US leads the world in online shopping activity and speed of delivery . Supply chains have spent decades investing in technology and building the information systems required to deliver on home delivery and service promises. More recently, venture capital has also invested in transportation and logistics, with PitchBook reporting $14.4 billion invested globally in privately owned freight, logistics, shipping, trucking, transportation management system (TMS), and supply chain tracking startups since 2013 . Not only do these changes affect transportation and logistics companies, but these changes affect peripheral sectors as companies reorganize their operations to service these new demands.
As customers are offered, and accept, shorter and shorter click-to-delivery times, delivery companies have less opportunity to make consolidated, efficient deliveries. Instead of waiting for more orders and sending out full trucks, vehicles are sent out to meet their quick delivery promise; reducing vehicle utilization. This increases the number of vehicles on the road, increases the cost per delivery, and increases vehicle emissions.
Significant impact on cities
It is the roads and sidewalks built by American cities and towns that enable this last mile delivery. In Seattle, 87% of buildings in greater downtown rely solely on the curb for freight access. These buildings have no off-street parking or loading bays.
Our cities were not built to handle the nature and volume of current freight activity and are struggling to accommodate growth . At the same time, delivery of goods is just one of the many functions of our transportation networks. The same roads and sidewalks are also used by pedestrians, cyclists, emergency vehicles, taxis, ride hailing services, buses, restaurants, and street vendors, to name a few.
Capacity on our transportation networks is increasingly scarce. Texas Transportation Institute’s 2019 Urban Mobility Report, a summary of congestion in America, is titled “Traffic is Bad and Getting Worse”. Over the past 10 years, the total cost of delay in our nation’s top urban areas has grown by nearly 47%. It is on top of this already congested network, that we add this growing last mile traffic. American cities have yet to make any headway with congestion, and delivery traffic both adds to, and suffers from, this condition.
To address congestion, many state Departments of Transportation are working to provide safe and competitive alternatives to single occupancy vehicle travel such as transit, bicycling, and walking. Other federal agencies are also working on addressing this issue, such as the Department of Energy, which has awarded UW and Seattle an EERE grant. In building dedicated bicycle facilities, one common solution is to convert the curb lane to a bike lane, removing commercial vehicle load and unload space. At the same time, American’s are increasingly using ride-hailing services such as Uber and Lyft . This also increases the demand for curb space as passengers request pickup and drop-off instead of parking their own vehicle off-street.
The result is too much demand for too little space, and there is ample evidence of a poorly functioning system. From a study in Seattle, 52% of vehicles parked in commercial vehicle load zones were passenger cars, and 26% of all commercial vehicles parked in passenger load zones. In New York City, UPS and Fedex received 471,000 parking violations in 2018. Everyone has seen an image of a truck parked in a bike lane, or been stuck behind a delivery truck occupying an entire residential street. While we might expect a small percentage of violations, these levels reflect a failure of planning and design to deliver reasonable alternatives to commercial vehicles, and a city that has not caught-up with the changes in supply chain and shopping patterns.
In addition to these operational challenges, commercial vehicles have impacts on American’s health and safety. Per mile, trucks produce disproportionately more carbon dioxide and local pollutants (NOx, PM) than passenger vehicles so a substitution of delivery trucks for passenger vehicles has the potential to increase emissions. However, delivery services also present an opportunity to reduce emissions per package as they can consolidate many packages into one vehicle; the same way transit or carpooling can be an emissions advantage over single occupancy vehicle trips. Research shows that in most cases a well-run delivery service would provide a carbon dioxide reduction over typical car-based shopping behavior. While there is the opportunity for delivery services to provide this emissions benefit, the move towards very fast delivery erodes that benefit as delivery services are unable to achieve the same level of consolidation and begin to look more like butler services.
Diesel powered vehicles, often used for the movement of freight, produce disproportionately more particular matter and NOx pollution than gasoline engines, so the use of these vehicles in urban areas, where human exposure levels are higher, has significant negative outcomes for human populations in terms of asthma and heart disease. This is particularly true for the very young, elderly, or immunosuppressed.
While it may seem intuitive that replacing a car trip to the store with a truck delivery would be bad for the city, in fact, delivery services can reduce carbon emissions and total vehicle miles travelled. This is because the truck is not just delivering to one home, but to many. In this sense, the truck delivery behaves like a transit vehicle or very large carpool. This can reduce congestion by reducing the number of vehicles on the road. Delivery trucks can be an asset when performing in this efficient manner because they consolidate many goods into a single vehicle reducing per package cost, emissions, and congestion impacts.
Banning trucks and requiring or encouraging the use of smaller vehicles INCREASES the number of vehicles and the vehicle miles travelled; exacerbating traffic and parking problems.
Growth in two and one-hour delivery INCREASES the number of vehicles and vehicle miles travelled; exacerbating traffic and parking problems.
The Urban Freight Lab as a Public and Private Sector Collaboration
Businesses are challenged by the high cost of the last mile, and the increasing time pressure for deliveries. Cities are working to manage congestion, the competing demands of many users, emissions, and intense pressure for curb space. This presents a complex set of problems, where:
- private carriers are struggling to comply with city regulations and remain financially competitive while meeting customer expectations
- customers are benefiting from high levels of convenience but also experiencing high levels of congestion and suffering from the effects of growing emissions
- cities and towns are struggling to meet demands of multiple stakeholders and enforce existing rules
All of this, in a context where there are very limited data regarding truck or commercial vehicle activity, numbers of deliveries, or other measures of efficiency. The Freight Analysis Framework , which compiles the nation’s most significant freight datasets such as the Commodity Flow Survey, breaks the country into 153 zones, so that most states can only see what came into or out of the state, not how vehicles move around within cities and towns. The more recently developed National Performance Management Research Data Set (NPMRDS) , presents truck specific data, and allows for highway speeds to be monitored at a county level, but does not show vehicle volumes, or give any insights into origin-destination patterns. At the national level, mode-specific datasets provide more spatial, temporal, and activity detail. For example, the Carload Waybill sample provides important data on rail cargo movements and the Air Operators Utilization Reports provide important data on airplane activity. Unfortunately, the Vehicle Inventory and Use Survey, which provided detailed data on truck and goods movements, was discontinued in 2002. This leaves cities and towns have no nationally consistent sources of or guidelines for collecting truck activity data.
The most economically efficient solutions to these challenges will be identified through collaboration between cities and private partners. One particularly successful and innovative solution can be found in the Urban Freight Lab at the University of Washington (https://urbanfreightlab.com/urban-freight-lab-0). As the director of the Urban Freight Lab, I have built a coalition of private companies and public agencies who work together to identify and measure problems, and develop and pilot-test solutions that will provide benefits for a diverse group of public and the private sector stakeholders. The goal is to find win-win solutions for businesses and city dwellers, and to avoid short-sighted solutions like blanket truck bans.
The Urban Freight Lab is successful because:
- All participants have skin in the game. Private sector contributions elevate public sector research funding and ensure that all participants fully engage. This is fundamentally different from an advisory board or oversight committee because members must report back to their leadership and justify participation with measurable returns on investment. This participation from the private sector improves relevance and timeliness of public sector support.
- Collaboration amongst the private and public sector ensures that products of the lab are as mutually beneficial as possible.
- Problems, evaluation metrics, and research ideas come from the group and are connected directly to real-world challenges faced, not the research directors, the public, or private sector alone.
- Private- and public-sector participants are senior executives who have the authority to make decisions in quarterly meetings. They do not need to return to the organization for approval.
- Cities need freight planning capacity but currently don’t have any. The work of the Urban Freight Lab fills gaps in problem definition, data collection, solution generation, orchestration and evaluation of pilot tests.
- Robust analysis is conducted by University researchers – they serve an important role in taking an unbiased view and base their analysis on data.
- Quarterly meetings are working meetings with detailed agendas and exit criteria. The focus is on making progress, making decisions, and moving forward, not simply information sharing.
- Private sector partners are operational and technical staff with knowledge of operations.
- Public sector partners represent a breadth of functions including planning, engineering, curb management, mobility, and innovation.
- University research focusses on practical outcomes and does not hide in theoretical concepts.
- Solutions are tested on the ground through pilots and real tests. The slow work of collaboration building and overcoming obstacles to implementation is part of the research.

The Seattle Department of Transportation represents the public-sector.
Seattle is a growing City and has now been ranked in the top 4 for growth among major cities for five consecutive years. It is a geographically constrained city surrounded by water and mountains, and boasts some of the highest rates of bike, walk, and transit commuting in the country ; with less than a quarter of City Center commuters now driving alone to work. It is a technologically oriented City; with the region serving as the home to many technology companies such as Amazon, Convoy, Facebook, Google, Microsoft, and Tableau. The City was one of the first to launch PayByPhone, electronic toll tags, weigh-In-motion, high-occupancy-toll lanes, passive bicycle counters, real-time transit monitoring, bike and car share programs, and most recently, an Open Data Portal . In this sense, the City provides an excellent example for experimentation where the public and private sector face intense pressure to look for new solutions and approaches; and levels of congestion and pressure that other US Cities can anticipate in their future as populations grow and infrastructure construction does not keep pace.
With this private- and public-sector funding the Urban Freight Lab has:
- produced foundational research on the Final Fifty Feet of the supply chain
developed and applied approaches to quantify urban freight infrastructure
developed and applied approaches to measure infrastructure
generated and tested approaches to reducing dwell time and failed deliveries in urban areas including common lockers
developed and implemented an approach to measuring the volume of vehicles entering and exiting the City of Seattle.
Ongoing work is supported in large part by a grant from the Department of Energy U.S. Department of Energy: Energy Efficiency & Renewable Energy (EERE) titled Technology Integration to Gain Commercial Efficiency for the Urban Goods Delivery System, Meet Future Demand for City Passenger and Delivery Load/Unload Spaces, and Reduce Energy Consumption. This project, funded by DOE, provides $1.5 million over 3 years with matching funds from the City of Seattle, Sound Transit, King County Metro, Kroger, the City of Bellevue, and CBRE. The project will evaluate the benefit of integrated technology applications on freight efficiency. Within the scope of this grant, Urban Freight Lab members and the Seattle DOT will be involved in developing and testing applications of technology in the Belltown area of Seattle that will increase commercial efficiency and reduce impact of freight activity on city residents .
Moving Forward
Shopping patterns have evolved, but our infrastructure has not. We need to rethink how we use our streets, curbs, and sidewalks if we want to maintain and grow our current shopping and delivery habits.
By consolidating many goods into a single route, delivery services could be an asset to communities; growing economic activity, reducing total vehicle miles travelled and associated carbon emissions, and supporting communities less dependent on cars. However, the current trend towards faster and faster deliveries; and businesses subsidizing delivery costs means we see lower vehicle utilization, higher numbers of vehicles and congestion, and increased emissions.
While some town and city governments have invested measuring the state of urban freight in their communities and developed improvements, most have limited resources and no guidance from the state or federal level. For example, they do not know how many trucks operate in the region, what they carry, whether the current curb allocation is satisfactory, or what benefit might result from improvements.
New modes, technologies, and operational innovations provide opportunities for win-win solutions. These new conditions may allow new modes such as electric assist cargo bikes to outcompete existing modes. Electric and hybrid vehicles can reduce both global and local pollutants. New technologies such as robotics, artificial intelligence, and electronic curbs may fundamentally shift the existing infrastructure paradigms. Private companies are ready to test these innovations, and the US and state DOTs can play a role in supporting these tests and conducting evaluations.
Investments in the freight system must include the last mile, and in particular the final fifty feet of the delivery route as a consideration to ensure economic vitality and support quality of life. This includes supporting towns and cities in investigating and understanding the current state of goods movement at the municipal scale, identifying and evaluating new solutions for cities and towns to adapt to changing supply chains, integrating freight planning and passenger planning, and ultimately providing healthy environments for businesses to thrive and great places to live.

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 scarce curb, buildings’ internal loading bays, and alley space
- How delivery people move with handcarts through intersections and sidewalks; and
- On the delivery processes inside urban towers.
Analysis of Online Shopping and Shopping Travel Behaviors in West Seattle
The purpose of this research is to explore consumers’ online shopping and in-person shopping travel behaviors and the factors affecting these behaviors within the geographical context of the study area of West Seattle.
West Seattle is a peninsula located southwest of downtown Seattle, Washington State. In March 2020, the West Seattle High Bridge, the main bridge connecting the peninsula to the rest of the city, was closed to traffic due to its increased rate of structural deterioration. The closure resulted in most of the traffic being re-distributed across other bridges, forcing many travelers to re-route their trips in and out of the peninsula. At about the same time, the COVID-19 pandemic caused business-shuttering lockdowns. Both events fundamentally changed the nature of shopping and the urban logistics system of the study area.
The Seattle Department of Transportation (SDOT) engaged the Urban Freight Lab (UFL) at the University of Washington to conduct research to understand current freight movements and goods demands in West Seattle and identify challenges related to the bridge closure to inform data-driven mitigation strategies. The study took place in two phases: the first phase documented the challenges experienced by local businesses and carriers through a series of interviews and quantified the freight trip generated by land use in the case study area1 ; the second phase, described in the current report, performed an online survey to understand online shopping and in-person shopping travel behaviors for West Seattle residents.
The main objectives of the current study are twofold:
- Describe online shopping and shopping travel consumer behaviors for West Seattle residents.
- Understand what factors influence consumer shopping behaviors, from accessibility to local stores, to the characteristics of goods purchased, to socio-economic factors.
Methods
To address these objectives, the research team designed an online questionnaire that was advertised through a West Seattle Bridge Closure-related SDOT newsletter and other local online media outlets during the spring and summer of 2022. The questionnaire asked respondents about their socioeconomic conditions (age, income, education, etc.), where they live and their access to transportation (vehicle ownership and types of vehicles), their online shopping behavior, the impact of the West Seattle High Bridge closure on their shopping habits, and about their most recent purchase for a given category of goods among clothing items, groceries, restaurant food, and household supplies. The questionnaire was collected anonymously, and no personally identifiable information was collected. A total of 1,262 responses were collected, and after data processing, the final sample data consisted of 919 responses, corresponding approximately to 1 percent of the study area population.
Comparing the socioeconomic characteristics of the sample with those of the West Seattle study population it should be noted that individuals identifying themselves as white and female and of older age were oversampled, while individuals with lower than a college degree and with annual income less than $50,000 were under-sampled. Therefore, the sample in general is more representative of a more affluent, older population.
Key Findings
The key findings are summarized as follows:
Online shopping is widespread for clothing items and restaurant food.
Respondents receive on average 5 deliveries per week, across all goods categories. 38.7 percent of the respondents reported performing their most recent shopping activity online, considering all goods categories. However, the frequency of online shopping varied across different goods categories. Most of the respondents that purchased groceries or household supplies reported having shopped in person (89 and 75 percent of the respondents respectively), while, in contrast, for those that purchased restaurant food and clothing items, two-thirds of respondents reported buying online in both categories. Online shopping is widespread in the clothing and restaurant food markets, but less in grocery and household supplies markets. Of the consumers that shopped online for restaurant food, 76 percent of them decided to travel to take out (also referred to as curbside pickup), and only 24 percent of them chose to have the meal delivered directly to their home.
Online shopping is more widespread among mobility-impaired individuals
Participants were asked whether they had a disability that limited physical activities such as carrying, walking, lifting, etc. Of the 918 participants, 98 (11%) responded that they did have a disability that fit this description. The share of respondents that shop online was higher among mobility-impaired individuals (30 percent online for delivery and 19 percent online for pick-up) compared to individuals that did not report any mobility impairment (23 percent online for delivery and 12 percent online for pick-up).
Driving is the predominant shopping travel mode
Of the sample of respondents, 96 percent reported having access to a motorized vehicle within their household. Driving is also the most common shopping mode of in-person travel, with 81.3 percent of respondents reporting that they drove to a store to shop. Walking is a distant second preferred shopping travel mode, with 13.1 percent of respondents reporting having walked to a store. Biking and public transit were rarely adopted as a shopping travel mode, together they were observed 5.6 percent of the time. Though included as a travel option, only 1 participant reported using a rideshare vehicle to shop.
Electrification in West Seattle
Of the respondents that have access to a motorized vehicle in their households, 9.8 percent of them reported owning an electric vehicle. Car ownership is much more widespread than bike ownership, with 51.6 percent of the respondents reporting having access to a bike. Among these, 15.5 percent of them said that at least one of their bikes is electric.
The 10-minute city
The average walking time across all types of goods purchased was 10 minutes. The average driving time, for those respondents that reported driving to a store, was also about 10 minutes, except for those who reported purchasing clothing items, which reported on average of 27-minute trip time (both using a private car or using public transit). The longest travel times are seen mostly for respondents that took public transit as a shopping travel mode.
Living in proximity to stores reduces driving and online deliveries
A higher number of stores within a 10-minute walking distance (0.5 miles) is correlated with a higher number of consumers choosing to walk to a store, compared to those that chose to drive to a store or that shopped online. This is true across all goods types, but it is more significantly seen in grocery shopping. Moreover, accessibility to commercial establishments at a walking distance has a stronger impact on reducing the likelihood of driving, and at a lesser magnitude, reduces the propensity of shopping online.
Delivery to the doorstep is the most common destination for online deliveries
For those that chose to buy online, the most common delivery destination was at the respondents’ home doorstep (84 percent of respondents reported receiving online deliveries at home). The second most frequently used delivery destination was parcel lockers (15 percent of respondents), with 12 percent of respondents making use of private lockers, while only 3 percent made use of public lockers. The remaining one percent received deliveries at other destinations (e.g. office or nearby store).
The West Seattle High Bridge closure incentivized local shopping
When asked about the impacts of the West Seattle Bridge closure on individual online and shopping travel behaviors, more respondents reported buying more locally and online, vs. traveling farther for shopping and buying in person.

Mapping the Challenges to Sustainable Urban Freight
Just as there has been a push for more climate-friendly passenger travel in recent years, that same push is building for freight travel. At the same time ecommerce is booming and goods delivery in cities is rising, sustainability has become a policy focus for city governments and a corporate priority for companies.
Why? Cities report being motivated to be responsive to residents, businesses, and the goals of elected leaders. Companies report being motivated by cost reduction, efficiency, branding and customer loyalty, and corporate responsibility.
For its part, Amazon in 2019 pledged to become a net-zero carbon business by 2040. In the wake of that pledge, Amazon financially supported this Urban Freight Lab research examining two key questions:
- What is the current state of sustainable urban freight planning in the United States?
- What are the challenges to achieving a sustainable urban freight system in the United States and Canada?
Because the research literature reveals that denser, more populous cities are the areas most impacted by climate change, we focused our analysis on the 58 cities representing the largest, densest, and fastest-growing cities in the U.S. found within the nation’s 25 largest, densest, and fastest-growing metro areas. Our population, growth, and density focus resulted in heavy concentration in California, Texas, and Florida and light representation in the Midwest.
Within those 58 cities, we reviewed 243 city planning documents related to transportation and conducted 25 interviews with public and private stakeholders. We intentionally sought out both the public and private sectors because actors in each are setting carbon-reduction goals and drafting plans and taking actions to address climate change in the urban freight space.
In our research, we found that:
- The overwhelming majority of cities currently have no plans to support sustainable urban freight. As of today, ten percent of the cities considered in this research have taken meaningful steps towards decarbonizing the sector.
- Supply chains are complex and the focus on urban supply chain sustainability is relatively new. This reality helps explain the myriad challenges to moving toward a sustainable urban freight system.
- For city governments, those challenges include a need to adapt existing tools and policy levers or create new ones, as well as a lack of resources and leadership to make an impact in the industry.
- For companies, those challenges include concerns about the time, cost, technology, and labor complexity such moves could require.
“Sustainability” can mean many things. In this research, we define sustainable urban freight as that which reduces carbon dioxide emissions, with their elimination—which we refer to as decarbonization—as the ultimate end goal. This definition represents just one environmental impact of urban freight and does not include, for example, noise pollution, NOx or SOx emissions, black carbon, or particulate matter.
We define urban freight as last-mile delivery within cities, including parcel deliveries made by companies like Amazon and UPS and wholesale deliveries made by companies like Costco and Pepsi. We do not include regional or drayage/port freight as those merely transit through cities and face distinct sustainability barriers.

Modeling of Urban Freight Deliveries: Operational Performance at the Final 50 Feet
The demand for goods and services is rapidly increasing in cities, in part due to the rise in online shopping and more varied delivery options. Cities around the world are experiencing an influx of goods pickup and delivery activities. The movement of goods within urban areas can be very constraining with high levels of congestion and insufficient curb spaces. Pick-up and delivery activities, specifically those that are out of vehicle activities, encompass a significant portion of urban goods movement and inefficient operations can negatively impact the already highly congested areas and truck dwell times. This dissertation aims to provide insights and data-driven approaches to support freight plans in various cities around the globe with a focus on urban freight deliveries. To accomplish this goal, this dissertation first proposes to discover the current delivery process at the final 50 feet by creating value stream maps that summarize the flow of delivery activities and times, and time variations between activities. The map will be based on the data collected from five freight-attracting buildings in downtown Seattle. Secondly, this research explores contributing factors associated with dwell time for commercial vehicles by building regression models. Dwell time, in this study, is defined as the time that delivery workers spend performing out-of-vehicle activities while their vehicle is parked. Finally, this dissertation predicts the total time spent at the final 50 feet of delivery, including dwell times and parking-related times through discrete event simulations for various “what if” delivery scenarios. Multi-objective simulation-based optimization algorithms were further used to discover the optimal numbers of parking and building resources (e.g. number of on and off-street parking capacity, number of security guards or receptionists). This aims to better understand how increased deliveries in urban cities can impact the cost distributions between city planners, building managers, and delivery workers. This will also identify the areas for improvement in terms of infrastructure and resources to better prepare for the future delivery demands based on various scenarios.

A Mobile Application for Collecting Task Time Data for Value Stream Mapping of the Final 50 Feet of Urban Goods Delivery Processes
Delivery options have become very diverse with online shoppers demanding faster delivery options (e.g, 2-day delivery, same day delivery options) and more personalized services. For this reason, transportation planners, retailers, and delivery companies are seeking ways to better understand how best to deliver goods and services in urban areas while minimizing disruption to traffic, parking, and building operations. This includes understanding vertical and horizontal goods movements within urban areas.
The goal of this project is to capture the delivery processes within urban buildings in order to minimize these disruptions. This is achieved using a systems approach to understanding the flow of activities and workers as they deliver goods within urban buildings. A mobile application was designed to collect the start and stop times for each task within the delivery process for 31 carriers as they deliver goods within a 62-story office building.
The process flow map helped identify bottlenecks and areas for improvements in the final segment of the delivery operations: the final 50 feet. It also highlighted consistent tasks conducted by all carriers as well as differences with given carrier type. This information is useful to help decision-makers plan appropriately for the design of future cities that encompass a variety of delivery processes.

Deliver it All: In an Age of Expanding Online Commerce, Is Home Delivery Greener Than Sending Full Truckloads of Goods to Stores and Then Customers Driving to Them?
In an age of expanding online commerce, is home delivery greener than sending full truckloads of goods to stores and then customers driving to them? A detailed regional study finds compelling answers.
Readers who were teenagers in the 1980s may remember driving to a Sam Goody store to buy music. You probably also remember your disappointment when sometimes the tape or CD wasn’t in stock when you arrived. Perhaps you returned to your car and headed for Tower Records to try your luck there.
Your kids would probably find this story inconceivable today. The advent of the internet has profoundly altered consumer expectations. Immediate gratification is getting closer by the day; you can now obtain your favorite song in seconds, and order and receive physical goods in as little as a few hours in some urban areas.
Today’s ninth-grader expects to find any product she wants in seconds and order it right away on her smartphone. What’s more, she expects that the order will be accurate, complete, well-packed, and easy to return if desired.
