Abstract
The methods contained in the Highway Capacity Manual are based on a traffic composition of local drivers familiar with roadway characteristics. The Manual allows for the incorporation of a driver population factor adjustment into freeway capacity calculations to reflect the influence of unfamiliar drivers. Unfortunately, the Manual offers very little guidance on the appropriate values of the factor.
This project used continuous count traffic data at a number of Florida freeway locations to estimate the appropriate values of the driver population factor. By relating speed-volume characteristics to measures of non-local driver populations, the importance of this factor was demonstrated. Estimates were made of the factor values based on a sample of locations in Florida.
