Abstract

The objective of this research study was to support the Traffic Census and Highway Performance Monitoring System (HPMS) Programs in identifying locations for motorized traffic data collection on public roads in California.  

 

The study analyzed the traffic census count locations for each District to determine at which Census count locations the automated and continuously collected Caltrans Performance Measurement System (PeMS) data could be used in lieu of manual traffic counts. 

 

Next, this research identified and evaluated count locations for motorized traffic data collection on non-State Highway System Routes to help meet Federal Highway Administration (FHWA) requirements for the Caltrans Highway Performance Monitoring System (HPMS) program.

 

Lastly, this research reviewed and summarized the emerging traffic data collection technologies and data sources appropriate for Caltrans HPMS and/or Census reporting purposes.
