At the exit of a toll gate with a single booth, vehicles arrive at random at a rate of 20 vehicles per minute. The service has an average rate of 22 vehicles per minute. However, due to variable toll fees, the service is also random with an average rate of 22 vehicles per minute. If the operator of the toll road in the previous problem wants to improve the current condition at the toll plaza, determine the new queue characteristics if the number of toll booths is increased to 2. Estimate the average waiting time of vehicles

At the exit of a toll gate with a single booth, vehicles arrive at random at a rate of 20 vehicles per minute. The service has an average rate of 22 vehicles per minute. However, due to variable toll fees, the service is also random with an average rate of 22 vehicles per minute. If the operator of the toll road in the previous problem wants to improve the current condition at the toll plaza, determine the new queue characteristics if the number of toll booths is increased to 2.

Vehicles arrive at a toll system at random at an average rate of 12 vehicles per minute. If there are 2 tollbooths each at random at an average of 6 seconds after services are done for every vehicle at the tollsystem, calculate the following:1. Queuing characteristics2. If one toll ticket booth is closed and service time is reduced by 3 seconds, what are theQueuing characteristics?3. Plot the arrival distribution curve for the traffic conditions stated above.
Vehicles arrive at a toll booth with a mean arrival rate of 2 veh/min (the time between arrivals is exponentially distributed). The toll booth operator processes vehicles (collect tolls) at a uniform deterministic rate of one every 20 seconds. What is the average length of queue (in vehicles), time spent in the system and waiting time spent in the queue?
Note: Read the question carefully and give me BOTH right solutions with clear calculations. Vehicles begin to arrive at a toll booth at 5 vehicles per minute from 7 AM to 8 AM. The booth opens at 7:15 AM and services at a rate of 3 vehicles per minute until 7:45 AM. From 7:45 AM until 8 AM the service rate is 6 vehicles per minute. Assuming D/D/1 queuing, (A) have all vehicles that arrived between 7AM and 8AM exited the queue? and (B) what is the total vehicle delay while the queue exists?
Vehicles arrive at a toll system at random at an average rate of 15 vehicles per minute. If there are 2 toll booths each at random at an average of 6 seconds after services are done for every vehicle at the toll system. Calculate the following:1.1 Average length of queue of vehicles1.2. Average waiting time in a queue1.3. Average time spent in a queue1.4. If one toll ticket booth is closed and service time is reduced by 4 seconds, what are the queuing characteristics of the system? And plot the arrival distribution curve for this traffic condition
The average queue length at the intersection of the two roads with a stop signs is 4 vehicles. If the arrival rate of vehicles at the stop sign is 300 vehicles per hour, determine the service rate of the road in vehicles per hour. Assume both arrival and departure rates are exponentially distributed.
2.) Queuing Theory: At a single toll booth, you were able to observe an average vehicle arrival rate of 10 vehicles per minute starting from 7:00 AM. 30 minutes later, average vehicle arrival rate has become 4 vehicles per minute and continues throughout the day at that rate. If the toll booth is able to process one vehicle every 10 seconds, how many minutes after 7:00 AM will the first queue clear up? What is the longest queue length, expressed in number of vehicles? Assume a D/D/1 queuing model.
Question. 2Propagation speed of 45 km/hr and that each toll booth takes 6 seconds to service a car.Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total end to-end delay?
Data on a traffic accident recorded on a certain intersection for the past 5 years has an accident rate of 416 per million entering vehicles. If the average daily traffic entering the intersection is 504 find the total number accidents during the 5 year period.
There are 10 vehicles in a queue when an attendant opens a toll booth. Vehicles arrive at the booth at a rate of 4 per minute. The attendant opens the booth and improves the service rate over time following the function μ(t) = 1.1 + 0.30t, where μ(t) is in vehicles per minute and t is in minutes. When will the queue clear, what is the total delay, and what is the maximum queue length? draw a figure
In this problem, assume a propagation speed of 45 km/hr and that each toll booth takes 6 seconds to service a car. Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total endto-end delay?
