Abstract
The paper analyzes elevated expressway off-ramp connections to arterial street intersection. Direct left-turns and U-turn left turns were analyzed in terms of travel time and delay. VISSIM 4.1 simulation models for direct left-turn and indirect left-turns were constructed. The simulation tests were executed under two traffic conditions. Delay and travel time of straight movements in the U-turn scenario were reduced by 40–90 percent, while delay and travel time of the direct left-turn increased. Research also showed traffic volume and composition can affect the results of this comparison.
