Caltrans Performance Measurement System

Status: Existing

Description

California's Performance Measurement System (PeMS) is an Internet–based tool that can be used to monitor conditions on urban freeways. PeMS will allow users to produce congestion monitoring reports using automatically collected data from sensors statewide.

An archive data system, PeMS is both a source and a user of real–time data from nearly 40,000 individual detectors spanning the freeway system across all major metropolitan areas in California. This regional element is provided for users of PeMS outputs. This element exchanges data with the ICMS data hub.
