The study was designed to make an evaluation of freeway traffic flow characteristics for several high standard geometric design features. The study evaluates and compares the effect of different ramp types, spacing and volumes on freeway capacity and operation. Collector-distributor roads, auxiliary lanes and lane drops are included. The primary measure of effectiveness used for this study was density (vehicles per lane-mile). Density was chosen rather than speed because it is a better indication of driving conditions. (Author)
