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

Alighting time/passenger = 1.8 sec and boarding time/passenger = 3 sec. Compute the dwell time at each stop and the total dwell time. (Assume the clearance time = 5 sec).
Consider the following data: · Average number of vehicles (overtaking - overtaken) = 1 • Average number of vehicles during trips in opposite direction of traffic flow = 336 · Average journey time when test vehicle is travelling with the stream = 8 min 31 sec. · Average journey time when test vehicle is travelling against the stream = 7 min 24 sec. Average journey time for the above data is min. %3D
