Road User Understanding of Bicycle Signal Faces on Traffic Signals

Christopher Monsere
Sirisha Kothuri
Bicycling is increasing in the United States – the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (NHTS, 2009). With the increase in bicycling rates, there is a critical need for cycling infras ... Read More

Effects of Earthquake-Induced Liquefaction on Bridge Foundations and Transportation Network Using CDSS

Arash Khosravifar
A magnitude 9.0 earthquake by the Cascadia Subduction Zone (CSZ) is believed to be capable of causing widespread soil liquefaction in the Pacific Northwest (PACNW). Affected infrastructures include highway bridges specifically the ones crossing the C ... Read More

Preliminary Analysis of Speed Limit Changes in Eastern Oregon

Christopher Monsere
Sirisha Kothuri
This report is the third in a series of reports examining issues in Oregon related to changes in posted speed limits. In 2004, a comprehensive report, “Impacts and Issues Related to Proposed Changes in Oregon’s Interstate Speed Limits1 ,” was p ... Read More

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies

Sirisha Kothuri
Christopher Monsere , Krista Nordback , Edward Smaglik
There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number ... 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

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
