WZPERFOMAT: A User-Friendly Tool for Monitoring Work Zone Performance
Work zones are essential for infrastructure development, but can often compromise safety and mobility. WZPERFOMAT is a free, user-friendly tool that integrates crash and probe data to automatically generate standardized performance metrics. This tool provides charts and reports at both the project and system levels, helping agencies meet federal requirements and improve their decision-making processes.
