Step 1Let me solve this problem step by step, focusing on the dilemma zone elimination strategies.
Step 2: Understanding the Dilemma Zone
The dilemma zone is a critical traffic engineering concept where drivers face an uncertain decision at an intersection when the traffic signal changes from green to amber. Drivers must quickly decide whether to stop or proceed through the intersection.
Final Answer
The correct method to eliminate the dilemma zone is (i) selecting an appropriate minimum duration for the amber signal phase. This approach provides drivers with a clear, safe window to decide whether to stop or proceed through the intersection.
