Data are obtained from the Caltrans Performance Measurement System (PeMS). Data are collected in real-time from over 25,000 individual detectors spanning the freeway system across all major metropolitan areas of the State of California.
PeMS is also an Archived Data User Service (ADUS) that provides over ten years of data for historical analysis. It integrates a wide variety of information from Caltrans and other local agency systems including:
- Traffic Detectors
- Lane Closures
- Toll Tags
- Census Traffic Counts
- Vehicle Classification
- Roadway Inventory
To use PeMS, you must apply for an account. Registration is free and takes only a few minutes. Accounts are typically approved within one to two business days.
