Optimizing Operation of Diverging Diamond Interchange with Automated Vehicles
The proposed research introduces an innovative traffic control method to optimize the operation of a diverging diamond interchange (DDI) in an automated driving environment. The DDI design is gradually gaining acceptance in many parts of the country because of its advantages over the conventional diamond interchange design, this research offers a new look into the potential benefits by the emerging automated driving technology in mitigating the drawbacks in DDI operations. This work includes the development of the algorithm through math modeling and computer simulation to control traffic flows through the DDI. The proposed control system is built on the premise that DDIs reduce both crossing and merging conflict points and that there is no longer a need for signal control for the side intersections.
