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 a survey to understand the current use of these strategies, and analyzed video from a number of geographically diverse locations employing these strategies to understand the impact the various strategies had on conflicts between bicycles and motor vehicles. The results from the field deployments and simulations were used to develop a practitioner-focused guidance document for guidance on the implementation of alternate control strategies.
