To help monitor data quality, the Connected Corridors team has developed a web-based visualization tool for tracking sensor health, both on the freeway and surface streets. Additional tools are currently in development to further assist the team with data quality analysis.

PEMS Sensor Availability Tool
For freeway monitoring, team members use the tool shown below to track average weekly loop sensor availability from Caltrans Performance Measurement System (PeMS). Every week, the tool automatically updates the aggregated status of each sensor category along I-210, I-605, and SR-134 within the corridor pilot area, as well as a section of I-10. Each row in the table represents one week; each column represents one sensor category. The values show the percentage of loops providing data for that week, calculated as the number of received detector-days of data divided by total possible detector-days of data.
