• 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.
