Congestion problems, especially at intersections, have been on the rise due to increased traffic volumes throughout mainline corridors in Puerto Rico. Although innovative intersection designs have been available for many years, such as the Michigan Left and the Superstreet, these have not been implemented in Puerto Rico. A congested intersection in the municipality of Mayagüez was chosen as the study site for this project. Initially the Michigan Left was the only intersection design considered for analysis. Simulation models indicated that this type of intersection design did not provide an acceptable level of service, thus suggesting that an alternate design was needed for the sex-leg intersection. Hence, a new intersection design that combined both Michigan Left and Superstreet concepts was modeled. The simulation model resulted in acceptable levels of service in most approaches, thus indicating that this intersection design is appropriate for six-leg intersections.
