Model Evaluation Plan for Work Zone Speed Safety Cameras

A Speed Safety Cameras (SSC) evaluation plan provides a structure for examining the SSC program’s progress toward achieving the program goals. Regular and frequent monitoring of certain performance aspects of the program confirms program reliability (i.e., that the system is functioning appropriately). This document provides foundational materials that agencies may use as a starting point when developing a plan and conducting an evaluation of work zone SSCs. Specifically, this document presents considerations for data collection and analysis with the understanding that the goals, available data, and nature of work zone SSCs are likely to vary for every agency.
