Analysis of Factors Affecting the Frequency and Severity of Freight-Involved and Non-Freight Crashes on a Major Freight Corridor Freeway

Posted by nbl42 on June 30, 2017

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

Modeling, Analysis, and Implementation of Pedestrian Priority at Signalized Intersections

Posted by nbl42 on

Sponsor: National Institute for Transportation and Communities (Prime: PSU)

PI: Edward J. Smaglik

Project Start|End Date: 2015 | 2016

In this project, NAU worked with Portland State University to develop guidance for practitioners for reducing the delay incurred by pedestrians at signalized intersections.  The team performed a simulation of various pedestrian control strategies to determine the impact of said strategies on all users, developed an algorithm specifically designed to reduce pedestrian delay within the confines of existing field equipment and operations, and… Read more

Investigation and Prototype Development of a Self-powered Bridge Structural Health and/or Traffic Monitoring Sensor Using Magnetic Shape Memory Alloys

Posted by nbl42 on June 30, 2015

Sponsor: Northern Arizona University

PI: Edward J. Smaglik

Project Start|End Date: 2014 | 2015

In this project, researchers investigated the feasibility of using power harvesting technology in a vehicle counting sensor with the overall goal of developing a sustainable traffic sensor.  The team performed laboratory tests to maximize the output of a power harvesting technology such that it would be able to power a device in situ.  A prototype was built and installed in a local street with the end result somewhat… Read more

Pilot Study: A Methodology for Addressing Bicycle / Motor Vehicle Conflict Zones

Posted by nbl42 on June 30, 2014

Sponsor: Northern Arizona University

PI: Edward J. Smaglik

Project Start|End Date: 2013 | 2014

In this project, researchers investigated the impact of using green paint and selected MUTCD signage to highlight bicycle – motor vehicle conflict zones.  The team worked with the City of Flagstaff to identify zones with a high bicycle – motor vehicle conflict.  Green paint was then applied at four locations along with the installation of the corresponding MUTCD sign.  Video data was collected before any improvements, with the… Read more

Development of Intersection Performance Measures for Timing Plan Maintenance Using an Actuated Controller Phase 2

Posted by nbl42 on June 30, 2012

Sponsor: Arizona Department of Transportation (ADOT)

PI: Edward J. Smaglik

Project Start|End Date: 2010 | 2012

In this project, researchers used standard traffic signal equipment and existing infrastructure to design and implement two prototypical devices for developing high-resolution performance measure data at signalized intersections.  The prototype included a hardware module and associated instructions for installation and most existing ADOT signalized intersections as well as a software solution for translating the data collected at the field into common performance measures that could be… Read more
