Washington State Pedestrian and Bicycle Miles Traveled Project

Principal Investigator: Krista Nordback

Estimates of vehicle miles traveled (VMT) drive policy and planning decisions for surface transportation. No similar metric is computed for cycling and walking. What approaches could be used to compute such a metric on the state level? This report di ... Read More

Shared Space and Bicyclists

Principal Investigator: Allison Duncan

Shared space is a traffic calming technique and design concept. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods study will be international in scope focusing on intersections in E ... Read More

Bicyclists’ Uptake of Traffic-Related Air Pollution: Effects of the Urban Transportation System

Principal Investigator: Alex Bigazzi

While bicyclists and other active travelers obtain health benefits from increased physical activity, they also risk uptake of traffic-related air pollution. But pollution uptake by urban bicyclists is not well understood due to a lack of direct measu ... Read More

Vehicle acquisition and disposal/ Multi-modal Household Vehicle Fleets and Residential Location Choices

Principal Investigator: Roger Chen

Vehicle availability significantly affects household travel behaviors and consequently affects the requirements for modeling and forecasting of household travel decisions under future or alternative scenarios. Household vehicle fleets are not acquire ... Read More

Street Portals: Urban User Interface 'Test Bed' Prototype for Bike Shares

Principal Investigator: Jason Germany

Co-Investigator: Philip Speranza

The objective of this research project is to develop a user interface “test bed” to measure the role of touchscreen kiosks with community connectivity. This interface test bed will apply the knowledge of interface design to the domain of public t ... Read More

Thinking Outside the (Half-Mile) Circle: Using the Real Estate Market to Establish Variations in Light Rail Station Catchment Areas

Principal Investigator: Susan Petheram

Dissertation Summary:This research empirically evaluates the extent of catchment zones for transit-oriented development (TOD) around light rail station areas using hedonic and spatial modeling techniques. Using a longitudinal approach, an asse ... Read More

Understanding Market Segments for Current and Future Residential Location and Travel Choices

Principal Investigator: Kelly Clifton

Co-Investigators: Jenny Liu , Roger Chen

This project aims to examine the connections between residential location choices and travel at the household level with an emphasis on identifying current residents' preferences for their future housing, neighborhood and transportation choices (coll ... Read More

Incorporating Pedestrian Considerations into Signal Timing

Principal Investigator: Sirisha Kothuri

The role of walking in the development of healthy, livable communities is being increasingly recognized. In urban areas, intersections represent locations where different modes converge, and are often viewed as deterrents to walking. This is due to t ... Read More

Travel Mode Choice Framework Incorporating Realistic Bike and Walk Routes

Principal Investigator: Joe Broach

For a number of reasons (congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few), the importance of walking and bicycling as transportation options will likely continue to increase. ... Read More

Pedestrian and Bicyclist Connectivity in the High-Speed Rail Alternatives Analysis

Principal Investigator: Jonathan Mueller

The United States needs to make wise investment choices to ensure the transportation needs of its population are met with the limited funding available. High-speed rail (HSR) is cited as a modern transportation alternative because it has several bene ... Read More

Relating Changes in Body Mass Index (BMI) to Changes in Neighborhood Environments for Relocating Young Adults: Analysis of 1997 National Longitudinal Survey of Youth Data

Principal Investigator: Gail Meakins

This research looks at census tract level characteristics of the built environment in relation to Body Mass Index (BMI) of neighborhood residents in both a cross sectional and longitudinal analyses, specifically asking how do the development density, ... Read More

Activity Spaces, Trajectories, and Agents: Assessing the Built Environment Effects on Walking Routes

Principal Investigator: Calvin Tribby

Dissertation Summary:Understanding the role of the built environment on active transportation is essential for encouraging healthy and active lifestyles and effectively guiding street rehabilitation and other environmental interventions. This ... Read More
