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.
1. Determine the space-hours of demand at the lot.
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.

Problem No.3 Space Requirements for a Parking Garage The owner of a parking garage located in a CBD has observed that 22 percent of those wishing to park are turned back every day during the open hours 8 a.m. to 6 p.m. because of a lack of parking spaces. An analysis of data collected at the garage indicates that 65 percent of those who park are commuters, with an average parking duration of 9 hours, and the remaining percentage are shoppers, whose average parking duration is 2 hours. If 25 percent of those who cannot park are commuters and the rest are shoppers, and a total of 220 vehicles currently park daily in the garage (i.e. parking spaces are 220), determine the number of additional spaces required to meet the excess demand.
