Pima County Speed Management evaluation and Strategic Development: Data-Driven Enforcement

Dec. 2017 - Dec. 2019

PI: Yao-Jan Wu, Ph.D., P.E. & Dean Papajohn, Ph.D.

PM: Stephen Wilson

The purpose of this study is to investigate the impact of deploying speed feedback signs, supported by some pattern of speed enforcement, to impact driver speed behavior in a consistent and predictable manner that will be beneficial to road operations and the utilization of enforcement resources. This project will explore the relationship between speed feedback signs, posted speed limit enforcement, and of speed of travel, and investigate how these features may act as a system to achieve better operations (in terms of number of crashes, reduced severity, and better utilization of capacity).
