• Abstract:
  This report documents the research project “Identifying Excessive Vehicle Idling and Opportunities for Off-Road Fuel Tax Credits for
  
  Stationary Operations in the Caltrans Fleet - Phase 1,” performed in response to a California Department of Transportation (Caltrans) Request for
  
  Proposals (RFP). The primary goals of this project were to identify baseline idling statistics for a selected set of test vehicles, identify excessive
  
  idling situations, identify stationary idling during work activities, and approximate fuel use for Caltrans vehicles under the various usage
  
  categories. A commercial-off-the-shelf (COTS) Automated Vehicle Location (AVL) system was used in each vehicle for GPS-based location,
  
  data sensing, and communications. AHMCT developed vehicle- and task-dependent criteria to define conditions for active work, and the needed
  
  trigger inputs to the commercial system to identify periods of active work. AHMCT instrumented a diverse fleet of 30 Caltrans vehicles, and
  
  supported extensive field data collection over at least a year for each instrumented vehicle. In addition, AHMCT developed the necessary backend
  
  database (DB) and front-end user interface (UI) to support researcher and Caltrans visualization and analysis of the resulting data set. This
  
  report includes analysis of the data set, summary reports, and a discussion of the visualization and analysis tools. Based on the quantitative data
  
  and analysis, the report provides recommendations for improvement in equipment and procedures. For example, there are cases where it may be
  
  reasonable to install idle shutdown systems in Caltrans vehicles in order to reduce idle time and fuel consumption without impacting task
  
  execution.
