Please solve this question. Subject: Transportation engineering 1 mum safety margin is 15 ft, centerline radius is 150 ft). 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. Assume parking efficiency is 0.90.
