Identifying Excessive Vehicle Idling and Opportunities for Off-Road Fuel Tax Credits for Stationary Operations in the Caltrans Fleet - Phase 1

The California Department of Transportation (Caltrans) investigated vehicle idling within its fleet. The project aimed to identify: baseline idling statistics for a selected set of test vehicles; excessive idling situations; stationary idling during work activities; and approximate fuel use under the various usage categories. A commercial automated vehicle location (AVL) system was used in each vehicle for GPS-based location, data sensing, and communications. A diverse fleet of 30 Caltrans vehicles was equipped with instruments to support extensive field data collection over at least a year. Based on the quantitative data and analysis, the report provides recommendations for improvement in equipment and procedures such as the installation of idle shutdown systems to reduce idle time and fuel consumption.
