Highway Effects on Vehicle Performance. (Recent Publications).

Publication No. FHWA-RD-00-164

A user-friendly model for personal computers, "Vehicle/Highway Performance" was developed to estimate fuel consumption and exhaust emissions related to modes of vehicle operations on highways of various configurations and traffic controls. It is intended

for highway designers and planners, and strategists optimizing Intelligent Transportation Systems. The model simulates operations of vehicles by evaluation of the vehicle external loads or propulsive demands, which are determined by longitudinal and lateral accelerations, positive and negative road grades, rolling resistance, and aerodynamic drag for various transmission gears. The computations of fuel consumption and air pollutant emissions are then related to the vehicle maps of fuel consumption and air contaminant emission rates as evaluated from large-roll dynamometer measurements for vehicle operations under various loads, speeds, and transmission gears or as may be estimated based on engine maps, speeds, loads, and vehicle drive-train characteristics.

The NTIS publication number is PB2002-100122. The publication is also available in PDF format at TFHRC'S Web site at www.tfhrc.gov/hnr20/00164.htm. It is divided into small files for easier downloading and printing.
