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
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
Reduction of Speed in Work Zones using ITS DMS Instant Feedback to Driver: Vehicle Speed versus Traffic Fine
Sponsor: Arizona Department of Transportation (ADOT)
PI: Craig Roberts (Smaglik Co-PI)
Project Start|End Date: 2010 | 2011
Research was conducted using a changeable message sign with radar (CMSR) at one work zone location on a four-lane, divided highway in Arizona. The CMSR provided feedback to drivers about the amount of their potential traffic fine, which was triggered by the radar captured speed as their vehicles approached the CMSR. This type of feedback has had only limited study according to the authors’ literature… Read more
