Using the narrow staircase example from the beginning of thi

Using the narrow staircase example from the beginning of this chapter, create a list of actions or tasks that could be implemented by the building manager that would allow people to use the staircase without risking a deadlock or starvation. If a deadlock occurs at a combination of downtown intersections, as shown in the figure below, explain in detail how you would identify that a deadlock has occurred, how you would resolve it after it happens, and how you would act to prevent it from happening again. A classic case of traffic deadlock on four one-way streets. This is \'gridlock, \' where no vehicles can move forward to clear the traffic jam.

Solution

A deadlock has occurred when no one vehicle can proceed forward, and aretherefore all stuck in traffic. In order to resolve this after it occurs, I would have tomake at least 2 of the vehicles in the middle of the intersection move out of the wayby turning right. Then forcing the other vehicles in the same lanes to stop to allowthe traffic from the opposite direction to pass, I would then alternate from lane tolane until the traffic has cleared and all vehicles were able to pass through. In orderto prevent this deadlock from happening again, I would have to create rules on howto allow traffic to move. This is where stop signs or traffic lights would become quiteuseful. Also, rules that do not allow a vehicle to stop in the middle of an intersection,this would prevent vehicles from blocking oncoming traffic from passing through
