Past Research
Modeling, Analysis, and Implementation of Pedestrian Priority at Signalized Intersections
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
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
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
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
Development of a Permanent Span Wire Specification for ADOT
Sponsor: Arizona Department of Transportation (ADOT)
PI: Edward J. Smaglik
Project Start|End Date: 2011| 2012
For this project, the research team at NAU worked with ADOT and independent consultants to develop a span wire specification and standard drawing set for the Traffic Signals and Lighting division of ADOT. The team research typical intersection geometries, equipment weights, signal head requirements, and other states’ span wire specification from across the country in developing a standard / specification that is unique in that it can… Read more
