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

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

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
