Arizona Tri-University Transportation Research Collaboration

Posted by nbl42 on

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

Evaluation of Inlaid Pavement Markings in Northern Arizona

Posted by nbl42 on

PI: Brendan J Russo

Sponsor: Arizona Department of Transportation (Prime: CivTech)

Project Start Date: 2016

This project involves an evaluation of the potential safety impacts of inlaid pavement markings on I-40 and I-17 in northern Arizona using the Empirical Bayes (EB) methodology.  Inlaid pavement markings are designed to better withstand snow plow activities and maintain their retroreflectivity better than standard pavement markings. The project entails collecting and analyzing crash, geometric, and environmental data for both treatment sites and control sites. Statistical software… Read more

Analysis of Operational Safety and Efficiency at the Megaregion Scale

Posted by nbl42 on

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

Posted by nbl42 on June 30, 2017

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

Posted by nbl42 on

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
