Description

The Mobility Performance Report (MPR) is prepared by California Department of Transportation (Caltrans) and district staff providing detailed data about highway system performance related to congestion and mobility. Caltrans collects vehicle counts and calculates speeds at all hours of the day and all days of the week in major metropolitan areas throughout California via the Caltrans Performance Measurement System. This information helps identify congestion bottlenecks and results in more cost-effective investments to improve performance of the State Highway System.
