Abstract

With the increasing population, there is an increasing need for traffic efficiency and road safety. Roadways that were once considered adequate may be unable to accommodate the growing number of vehicles on the road. In this paper, we analyze the I-280/Wolfe Road Interchange to determine its safety and efficiency inadequacies and propose an improved interchange design to fix these issues. Our analysis reveals that there is room for improvement in the safety of drivers, bikers, and pedestrians, as well as opportunities to enhance the efficiency of sections of the road that require it. We identified the lack of protective barriers on Wolfe Road, as well as a high traffic demand in the northern intersection in the southbound direction, to be major issues to address. To address these issues, we designed a new interchange that adds an additional lane to Wolfe Road in the southbound direction and adds barriers between the vehicle lane and the bike lane. With these improvements, the roadway will be safer and more efficient, keeping vulnerable users protected and accounting for future roadway demand.
