Past Research
Arizona Tri-University Transportation Research Collaboration
Sponsor: Arizona Board of Regents – Research Innovation Fund (Prime: U of A)
PI: Edward J. Smaglik
Project Start|End Date: 2016 | 2018-12-31
The purpose of this project is to define and develop a pilot portfolio of transportation projects around a central theme that can be executed within the structure and processes of a transportation research center. Each of the research projects in the portfolio (7 total) is specifically identified and includes research partners from more than one of the state universities… Read more
Analysis of Operational Safety and Efficiency at the Megaregion Scale
Sponsor: Arizona Board of Regents – Research Innovation Fund (Prime: U of A)
PI: Brendan J Russo
Project Start|End Date: 2017 | 2018-12-31
Transportation safety management at the megaregion level is critical for safe and efficient travel across the entire functional region. Even in megaregions contained within a single state, it is important for safety planning officials (at the state, metropolitan planning organization (MPO), county, or municipality level) to consider the safety performance of a megaregion as a whole. This project investigates… Read more
Improving Adaptive / Responsive Signal Control Performance: Implications of Non-Invasive Detection and Legacy Timing Practices
Sponsor: Oregon Department of Transportation (ODOT)
PI: Edward J. Smaglik
Project Start|End Date: 2014 | 2017
In this study, NAU led a team of three universities to determine the impact the use of non-invasive vehicles has on adaptive control. The research team developed a home-grown data collection device that was used to collect event-based detection data at multiple sites across the state of Oregon. This collected data and associated products were then modeled and used to provide guidance for the DOT for… Read more
Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies
Sponsor: National Institute for Transportation and Communities (Prime: PSU)
PI: Edward J. Smaglik
Project Start|End Date: 2015 | 2017
In this project, NAU worked with Portland State University to develop guidance for practitioners for reducing bicycle-motor vehicle conflicts at signalized intersections. The team performed a simulation of various alternate signal control strategies to determine the impact of said strategies on all users (Leading Bike Interval, Split Leading Bike Interval, and Bike Scramble were three of the strategies), reached out to practitioners via… Read more
Analysis of Factors Affecting the Frequency and Severity of Freight-Involved and Non-Freight Crashes on a Major Freight Corridor Freeway
Sponsor: Arizona Board of Regents – Research Innovation Fund (Prime: U of A)
PI: Brendan J Russo
Project Start|End Date: 2016 | 2017
Traffic crashes cost society billions of dollars each year as a result of property damage, injuries, and fatalities. Additionally, traffic crashes have a negative impact on mobility, as they are a primary cause of non-recurring delay. With the Interstate 10 corridor between the ports of Los Angeles and Houston being one of the most vital links for goods movement… Read more
