CALIFORNIA'S PERFORMANCE MEASUREMENT SYSTEM: IMPROVING FREEWAY EFFICIENCY THROUGH TRANSPORTATION INTELLIGENCE

California's Performance Measurement System (PeMS) was developed more than three years ago to enhance freeway systems productivity. PeMS collects and stores data from California loop detectors and converts the data into useful information. California plans to deploy the PeMS statewide in July, providing timely reports for decision makers, identifying and resolving traffic bottlenecks, determining travel times and optimal routes, and much more.
