Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies

Sirisha Kothuri
Christopher Monsere , Krista Nordback , Edward Smaglik
Over the last decade there has been increased interest in promoting active and sustainable transportation modes such as bicycling and walking especially in urban areas, as a means to alleviate congestion, lower emission levels and improve personal he ... Read More

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

Narratives of Marginalized Cyclists: Understanding Obstacles to Utilitarian Cycling Among Women and Minorities in Portland, Oregon

Amy Lubitow
Research has demonstrated that everyday or utilitarian forms of cycling are most likely to generate positive population-level health impacts (Garrard et al., 2012), yet significant deterrents to routine cycling remain, particularly for women and min ... Read More

Exploring Drivers’ Attitudes and Behaviors toward Bicyclists: The Effect of Explicit and Implicit Attitudes on Self-Reported Safety Behaviors

Tara Goddard
Bicycling in the United States is disproportionately unsafe as a transportation mode. Despite comprising a smaller share roadway users, bicyclists are twelve times more likely to be killed in a traffic crash with a car than car occupants (Pucher and ... Read More

Impact of Cascadia Subduction Zone Earthquake on the Seismic Evaluation Criteria of Bridges

Peter Dusicka
ODOT project page: http://www.oregon.gov/ODOT/TD/TP_RES/docs/stage1/2014stageone/14_087_Seismic_Evaluation_Criteria.pdf Under our current seismic design code, bridge designers ... Read More

Shared Space and Bicyclists

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

Evaluation of Speed Activated Displays on Curves

Christopher Monsere
This project is a national demonstration project to evaluate the effectiveness of dynamic speed signs on high crash curves on two-lane rural roadways in seven states to decrease speeds and reduce crashes. The team has installed and is monitoring sign ... Read More

Bridge Seismic Retrofit Measures Considering Subduction Zone Earthquakes

Peter Dusicka
Seismic retrofit implementation in the state has been minimal due to a lack of funding, and when retrofitshave occurred, the scopewas typically limited to phase I retrofit by providing restrainers for keeping the superstructure from sliding from the ... Read More

Safety Effectiveness of Pedestrian Crossing Enhancements

Christopher Monsere
Miguel Figliozzi
The objective of this research is to estimate the effectiveness of PCEs on multimodal safety in Oregon design contexts to derive CMFs calibrated to Oregon (i.e. not only pedestrian crashes but also motorized vehicles and bicycle crashes in the vicini ... Read More

Application of Interactive Video Sensing and Management for Pedestrian and Bicycle Safety Studies

Wu-chi Feng
Christopher Monsere , Miguel Figliozzi
As video data collection and storage technologies become ubiquitous and inexpensive, transportation agencies struggle to process and extract "intelligence" or useful information from growing libraries of archived video data. In some cases us ... Read More
