Mobility Performance Report (MPR)

In 2009, Caltrans began preparing the Mobility Performance Report (MPR), a new congestion report using data collected from every day of the year. This report replaces the Highway Congestion Monitoring Program (HICOMP) Report. The MPR represents the completion of a transition to an improved way of measuring congestion. For a full explanation of this transition, and the differences between the HICOMP Report and the MPR, read the first chapter of the MPR 2009.
