Thank you everyone for sharing your traffic jam quiz answers. Everyone's solutions were great and we all learned a lot of things. We can choose only one winner though...so we selected Tanveer Tausif as the winner of this quiz contest. We selected the winner's answer because it was mostly innovative, but practical too even though it may take a long time to implement it.
