Racial Bias in Drivers' Yielding Behavior at Crosswalks: Understanding the Effect

Kimberly Kahn
This project explores social identity factors (race and gender) that influence drivers’ behavior in interactions with pedestrians at crosswalks. One dangerous potential point of conflict for pedestrians within the transportation system is interacti ... Read More

Evaluation of Roadway Reallocation Projects

Miguel Figliozzi
In the last decade there has been a national trend toward projects that involve roadway space reallocation across modes. Many of these projects may include road diets and are typically very controversial when automobile travel lanes and/or curbside ... Read More

How Do Stressed Workers Make Travel Mode Choices That Are Good For Their Health, Safety, and Productivity?

Liu-Qin Yang
This proposal integrates the perspectives from transportation and psychology research by focusing on the relations between commuting stress, commuting mode choice, and consequences of such choice for commuters' health, travel safety, and work perform ... Read More

Exploring the positive utility of travel and mode choice

Patrick Singleton
Traditionally, travel is considered a disutility to be minimized, and travel demand is derived from activity demand. Recently, scholars have questioned these axioms, noting that some people may like to travel, use travel time productively, find other ... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Sirisha Kothuri
Christopher Monsere , Edward Smaglik
The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle ... Read More

Improving Trip Generation Methods for Livable Communities

Kelly Clifton

Recent efforts to improve trip generation data available for transportation impact analysis of new development include the collection of multimodal trip generation data, development of models that account for the built environment, and new recommend ... Read More

Online Non-motorized Traffic Count Archive

Krista Nordback
Kristin Tufte
Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with ... Read More

Investigation of Bicycle and Pedestrian Continuous and Short Duration Count Technologies in Oregon

Krista Nordback
Miguel Figliozzi
While motorized traffic counts are systematic and comprehensive, bicycle and pedestrian traffic is often unknown, which results in lack of planning or infrastructure for active transportation modes. Although there are many emerging technologies to co ... Read More

Active Travel Behavior and Spatial-Temporal Land Use Mixing

Steven Gehrke
Urban policies have emphasized the importance of land use mixing as an intervention beholding of lasting planning and public health benefits. Transportation planners have identified potential in efficiency gains achieved by increasing land use mix an ... Read More

Development of a Pedestrian Demand Estimation Tool

Kelly Clifton
There is growing support to improve the quality of the walking environment and make investments to promote pedestrian travel. Such efforts often require analytical non-motorized planning tools to estimate levels of pedestrian demand that are sensitiv ... Read More

Transportation Leadership Education

Nathan McNeil
The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors p ... Read More

Washington State Pedestrian and Bicycle Miles Traveled Project

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
