PARKING STUDIES
PROB 1. Data collected at a parking lot indicate that a total of
300 cars park between 8 a.m. and 6 p.m. 10% of these cars
are parked for an average of 2 hr, 30% for an average of 4 hr,
and the remaining cars are parked for an average of 10 hr.
Determine the space-hours of demand at the lot
PROB 2. If 10% of the parking bays are vacant on average
(between 8 a.m. and 6 p.m.) at the parking lot of PROB1,
determine the number of parking bays in the parking lot.
Assume an efficiency factor of 0.85
Data collected at a parking lot indicate that a total of 300 cars park between 8 a.m. and 5 p.m. 5% of these cars are parked for an average of 2 hr, 20% for an average of 3 hr, 10% for an average of 4 hr, and the remaining cars are parked for an average of 9 hr. (a) Determine the space-hours of demand at the lot. (b) If 10% of the parking bays are vacant on average (between 8 a.m. and 5 p.m.) at the parking lot, determine the number of parking bays in the parking lot. Assume an efficiency factor of 0.90. (c) The owner of the parking lot is planning an expansion of her lot to provide adequate demand for the following 10 years. If she has estimated that parking demand for all categories will increase by 3% a year, determine the number of additional parking bays that will be required.
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?

The table below gives the results of the survey. The number of vehicles coming in and out of the parking lot for a time interval of 5 minutes is shown in the table. Find the accumulation, total parking load, average occupancy and efficiency of the parking lot. Note: XY= 100- last two digits of your student number. For example, if your student number is 190786, then XY= 100-86= 14.

The ticketing booth to enter the parking lot can only serve the vehicles at 1000 veh/hour until 7:15 AM, after which the service rate increases to 2000 veh/hour. Assuming D/D/1 queuing, draw a queuing diagram for this situation.

- 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.
