Statistical Inference for Multimodal Travel Time Reliability

Avinash Unnikrishnan
Miguel Andres Figliozzi , Subhash Kochar
Travel time reliability is a key metric of interest to practitioners and researchers. There are several metrics available for travel time reliability - buffer index, planning index, probability of travel time being higher than a specific value, etc. ... Read More

Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LIDAR Sensors

Taylor Li
Sirisha Kothuri , Xianfeng (Terry) Yang
Pedestrian safety is critical to improving walkability. Although walking trips have increased in the last decade, pedestrian safety remains a top concern. In 2018, 6,283 pedestrians were killed in traffic crashes representing the most deaths since 19 ... Read More

Access to Opportunities: Redefining Planning Methods and Measures for Disadvantaged Populations

Arlie Adkins
Stephen Mattingly
This project will be made up of two separate studies that together will investigate areas where transportation planning and engineering can better serve disadvantaged and underserved communities. An interdisciplinary team of planning and public healt ... Read More

Data-Driven Mobility Strategies for Multi-Modal Transportation

Yao-Jan Wu
Xianfeng (Terry) Yang , Sirisha Kothuri
By using various modes (e.g., walking, cycling, automobile, public transit, etc.), multi-modal transportation systems are effective in increasing people’s travel flexibility and reducing congestion. Hence, it is critical to understand how roadway s ... Read More

Understanding Factors Affecting Arterial Reliability Performance Metrics

Avinash Unnikrishnan
Sirisha Kothuri , Jason Anderson
In recent years, the importance of travel time reliability has become equally important as average travel time. However, the majority focus of travel time research is average travel time or travel time reliability on freeways. In addition, the identi ... Read More

Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development

Kristina Currans
In 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines and methods for evaluating development-level transportation impacts, specifically vehicular impacts (Institute of Transportation Engineers 1976). Dec ... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Sirisha Kothuri
Christopher Monsere
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

Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots

Miguel Andres Figliozzi
Robert Bertini
Most urban vehicle miles traveled take place along arterials and collector streets. Arterials and collector streets are also essential to provide accessibility and provide mobility for public transportation fleets; these roadways constitute the back ... 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

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Andres Figliozzi
Christopher Monsere
Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may le ... Read More

Lessons from the Green Lanes: Evaluating Protected Bike Lanes in the U.S.

Christopher Monsere
Jennifer Dill , Kelly Clifton , Nathan McNeil
This report presents finding from research evaluating U.S. protected bicycle lanes (cycle tracks) in terms of their use, perception, benefits, and impacts. This research examines protected bicycle lanes in five cities: Austin, TX; Chicago, IL; Portla ... Read More

Lightweight Buckling Restrained Brace Prototype Evaluation

Peter Dusicka
Buckling restrained brace (BRB) is a structural component that has been developed to provide known and repeatable strength in both tension and compression. Over the last couple ofdecades, BRBs have seen broad adoption in buildings in areas ofmoderate ... Read More
