Evaluation of Transportation Safety and Security Barriers in Bicyclist Accessibility

Posted by ab3824 on September 29, 2022

Sponsor: U.S. Department of Transportation, Pacific Southwest Region 9 UTC

PI: Steven R. Gehrke

Co-PIs: Brendan J. Russo and Edward J. Smaglik

A continuation of automobile dependence over the past half-century within American cities has resulted in significant public health, environmental, and economic challenges. The further motivation of bicycling as a utilitarian and sustainable travel alternative has been identified as a viable solution to address societal concerns regarding physical inactivity, climate change, and transportation-related inequities. However, to date, a profound… Read more

Automated Identification of Traffic Detector Malfunctions

Posted by sj765 on December 30, 2020

Sponsor: Oregon Department of Transportation (ODOT)

PI: Dr. Edward Smaglik, Co-PI: Dr. Brendan Russo

Start Date: January, 2020

Proper operation of transportation facilities is dependent upon reliable, accurate traffic sensing equipment; faulty detection equipment can result in unsafe and/or inefficient operation. A recent ODOT project, SPR-781 entitled, “Improving Adaptive / Responsive Signal Control Performance: Implications of Non-Invasive Detection and Legacy Timing Practices” uncovered wide spread issues of data quality irrespective of detector technology (within that work,… Read more

Evaluation of Emerging Transportation Technologies: KHA Emergency Vehicle Preemption in the City of Mesa / Maricopa County

Posted by sj765 on

Sponsor: Maricopa Association of Governments

PI: Dr. Edward Smaglik, Co-PI: Dr. Brendan Russo

Start Date: February, 2020

As a member of the Tri-University Task Force (NAU, ASU, and UA), NAU is leading an evaluation of Kimley-Horn and Associates’ Smart Priority technology, funded by the Maricopa Association of Governments and installed at intersections in the City of Mesa, Arizona and Maricopa County.  The product is a software module that interfaces directly between the Fire Department’s Computer Aided… Read more

Development of Cost-Effective Sensing Systems and Analytics (CeSSA) to Monitor Roadway Conditions and Mobility Safety

Posted by sj765 on

Sponsor: PSR9 UTC

PI: Dr. Chun-Hsing Ho

Dates: 01/06/2020-01/05/2021

The project presents a pavement sensing system along with a list of promising computing models that can be used to predict pavement conditions using a vehicle-based sensing technology. The project started with data acquisition obtained from the previous field data collection followed by a series of data computing using machine leaning methods to determine a promising computing algorithm. Subsequently,… Read more

Impacts of Intersection Treatments and Traffic Characteristics on Bicyclist Safety

Posted by nbl42 on November 1, 2019

Sponsor: Oregon Department of Transportation (ODOT)

PI: Brendan J. Russo, Co-PI: Edward J. Smaglik

In urban and suburban locations, intersections are where a variety of transportation modes converge, thus leading to an increased potential for conflicts, including those between bicyclists and motor vehicles. A common crash type involving bicycles at intersections is the “right/left-hook” where a right/left-turning vehicle collides with a through bicyclist. While various geometric treatments and signal control strategies (e.g. bike boxes, mixing zones, leading bike interval (LBI), split… Read more
