Comprehensive Work Zone Mobility Performance Management Across Project Stages

Abstract:

The California Department of Transportation (Caltrans) uses its Performance Measurement System (PeMS) as the key platform for monitoring and managing work zone performance. PeMS is a comprehensive roadway performance monitoring system consisting of roadway sensors for data collection, a web-based data warehouse, and a data analytics suite. Caltrans planners and engineers use PeMS to proactively manage work zone impacts across all project stages by:

  • Estimating work zone impacts as part of pre-closure planning and analysis including lane requirements visualization and delay estimation;
  • Monitoring and managing impacts during construction through dynamic reporting of road closure activity and status, real-time delay assessment, and detour route performance analysis;
  • Analyzing and documenting project impacts and lessons learned including volume, throughput, queue length, delay, and incidents (including impacts on detour routes); and
  • Using data archived in PeMS to better plan and design work zones and to compare real-time performance against historical performance.
