Samenvatting
The objective of this work was to determine the passenger car equivalent value for fourteen different vehicle types under varying traffic and roadway geometry conditions. This was accomplished by analyzing field data collected in several states on both two-lane and four-lane highways. Data included headways, speeds and travel times by vehicle type, traffic volume condition, and roadway section type. An analytical model was developed to estimate passenger car equivalent values based upon speed distributions, traffic volume, and vehicle type. The calibrated model was used to estimate passenger car equivalent values for fourteen vehicle types under the specified typical conditions for two-lane and four-lane rural highways.
