Research Projects

Summary:
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.

Summary:
The Urban Freight Lab (UFL) at the University of Washington is partnering with ECONorthwest and Cityfi to develop a research product for the National Cooperative Highway Research Program (NCHRP) on the topic of revenue strategies for new mobility options. The team will analyze the public sector’s potential role in using revenue-related strategies to encourage or discourage new mobility options in personal mobility and goods delivery. The objective of this research is to develop a toolkit for transportation agencies that addresses how revenue-related strategies (e.g., taxes, fees, and subsidies) support policy objectives and shape the deployment of new mobility options. The toolkit can assist agencies to develop, evaluate, implement, and administer revenue-related strategies for new mobility options that transport people and goods.

Summary:
In Phase 2 of the West Seattle Bridge Case Study, the research team will shift the focus from business establishments to consumers. In particular, we will explore consumer behavior, defined as how people choose to buy goods and services and where they buy them, to better understand residential demand and accessibility of goods for WS residents.  

Summary:
This study will use a driving simulator to design a simulation experiment to test the behavior of commercial vehicle drivers under various parking and delivery situations and to analyze their reactions. The ability to modify the simulator’s environment will allow the researchers to relatively easily test a range of scenarios that correspond to different delivery and parking situations, such as changing road characteristics (land use, number of travel lanes, nearby signals, traffic in adjacent lanes), curb allocations (paid parking, commercial vehicle loading zones, passenger load zones), and other road users (passenger cars, ridehailing vehicles, bikes). In addition to monitoring behavior and decision-making, the simulator can also monitor distraction (through eye tracking) and the stress level of drivers (through galvanic skin response) when making these decisions and interacting with other road users. Analyzing parking decisions and driver stress levels based on roadway and driver characteristics will provide insights on travel behaviors and the parking decision-making process of commercial vehicle drivers, and will help city planners improve street designs and curb management policies to accommodate safe and efficient operations in a shared urban roadway environment. This study is intended to fill knowledge gaps and serve as a valuable resource for policy makers, transportation engineers, and urban planners.

Summary:
This project aims to develop a city-scale dynamic curb use simulation tool and an open-source curb management platform. The envisioned simulation and management capabilities will include dynamically and concurrently controlling price, number of spaces, allowed parking duration, time of use or reservation, and curb space use type (e.g., dynamic curb space rezoning based on supply and demand). Researchers will design, implement, and test a curbside resource usage platform for fleet vehicles communications at commercial vehicle load zones (CVLZs), passenger load zones (PLZs), and transit stops, and perform demonstrations with stakeholder agencies and provide pathways to practice for promising curb allocation policies.

Summary:
Seattle DOT has engaged the Urban Freight Lab to conduct research to explore strategies to alleviate congestion impacts and minimize the disruption of goods and service delivery to West Seattle during the closure of the West Seattle High Bridge, which connects the West Seattle peninsula to the rest of the city.

Summary:
This research aims to develop innovative methods for managing curb lane function and curb access. The rapid rise of autonomous vehicles (AV), on-demand transportation, and e-commerce goods deliveries, as well as increased cycling rates and transit use, is increasing demand for curb space resulting in competition between modes, failed goods deliveries, roadway and curbside congestion, and illegal parking.

Summary:
The City of Seattle Department of Transportation (SDOT) has engaged the Urban Freight Lab to conduct research on the impacts of a Freight- and Transit-only lane (FAT lane) that was in place in January 2019, during the closure of the Alaskan Way Viaduct (a major thoroughfare) in Seattle and reduction of capacity in an already congested road network. The research findings will be used to understand the FAT Lane's performance towards achieving city goals and to guide development of future FAT Lane projects.

Summary:
The Ballard Cordon Data Collection for Trucks and Cars is an analysis research project to be conducted by the Urban Freight Lab for the City of Seattle Department of Transportation (SDOT).

Summary:
This project aims to improve understanding of how coastal marine transportation systems would be disrupted in natural hazard events, how such disruption would impact coastal communities, and what strategies could effectively address this risk. Focusing on the movement of people and goods in the emergency response phase of a disaster, the study will develop new tools, information, and risk assessments to support preparedness planning by local and provincial governments and the transportation sector. The research will deliver: (1) workshops for engaging government and transport sector stakeholders; (2) a framework for assessing coastal community resilience to shipping disruption; (3) a simulation tool based on this framework; and (4) specific findings and recommendations for two case studies – a detailed analysis of catastrophic earthquake risk in British Columbia and exploratory analysis of hurricane risk in Atlantic Canada.

Summary:
The Urban Freight Lab conducted an alley inventory and truck load/unload occupancy study for the City of Seattle. Researchers collected data identifying the locations and infrastructure characteristics of alleys within Seattle's One Center City planning area, which includes the downtown, uptown, South Lake Union, Capitol Hill, and First Hill urban centers. The resulting alley database includes GIS coordinates for both ends of each alley, geometric and traffic attributes, and photos.

Summary:
The Supply Chain Transportation & Logistics Center and Seattle Department of Transportation worked in collaboration with employers, transit operators, and transportation network companies (TNCs) to test a variety of strategies to mitigate the traffic impacts of TNC pick-ups on the greater transportation network and improve safety for passengers and drivers. Strategies included increasing the number of passenger loading zones in high-traffic pick-up areas and geofenced pick-up or black-out areas.

Summary:
The purpose of this research is to improve our understanding of the interactions between heavy vehicles and other users in an urban environment, in particular, in cases where commercial vehicle activity disrupts the activity of pedestrians and bicyclists. The research approach includes both the observation of current practice and evaluation of infrastructure and simulation of roadway user behavior. This information will support better roadway and load zone design guidelines, which will allow our urban street system to operate more efficiently, safely, and reliably for all users.

Summary:
Part of the Final 50 Feet Research Program, this project contains: a curb occupancy study, a survey of First and Capitol Hill Loading Bays, a pilot test at Seattle Municipal Tower, and the development of a toolkit. Taken together with the Urban Freight Lab's earlier private infrastructure inventory (Seattle Center City Alley Infrastructure Inventory and Occupancy Study 2018) in Downtown Seattle, Uptown, and South Lake Union, this project finalizes the creation of a comprehensive Center City inventory of private loading/unloading infrastructure. The study also provides the city with on-the-ground data on the current use and operational capacity of the curb for commercial vehicles, documenting vehicle parking behavior in a three-by-three city block grid around each of five prototype Center City buildings: a hotel, a high-rise office building, an historical building, a retail center, and a residential tower. Researchers also tested a new urban goods delivery system strategy: Common Carrier Locker Systems. Tools used by the Urban Freight Lab are publicly available in an Urban Goods Delivery Toolkit, a one-stop-shop for planners to replicate this work in other cities.
