The study quantified the extent of excess travel due to inefficient highway navigation for non-commercial vehicles in the United States in terms of both distance and time. Estimates of the consequences of this excess travel in terms of vehicle operating costs, accident potential and lost time are presented. Potential remedial measures are described and evaluated. It was found that recoverable navigational waste amount to 6.4 percent of all distance traveled by non-commercial vehicles and 12.0 percent of all time spent in such travel. The estimated costs to individuals and to society of this excess travel is estimated at $45.7 billion considering only vehicle operating and accident costs and the value of time. Additional, unquantified but significant costs are incurred due to increased air and noise pollution and increased requirements for highway maintenance and operations. Excess travel due to deliberate waste, i.e. the use on non-optimizing route selection criteria, and excess time due to failures in real-time route selection were not addressed.
