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.
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
1. A total of 5,000 person-trips are made between a commercial district and a residential area during
the PM peak hour. Commuters have two modes available, including private automobile and a light-
rail transit system. The following utility function was calibrated using data from the study area from
users of these two modes:
U 3D -0. 50T1 — 0. 50T, — 2. 00С
Data summarizing the operational characteristics and costs associated with each mode are provided in
the following table.

A bus line operates in mixed traffic and caries 4000 passengers per peak hour at an average speed of 10 mi/h. Typically each bus makes two scheduled stops per mile and is interrupted by the traffic- control system and other vehicles six times per mile.

- Through the Walla Walla Road to the entrance of the E-1 parking lot at the University of Washington, vehicles begin to arrive from 7:40 A.M. at a uniform deterministic rate of 480 vph until 8:20 A.M. and from then on at 120 vph. It takes 10 seconds for a vehicle to go through the paying process at the gate. If the parking lot is open at 8:00 A.M., determine (a) when the queue will dissipate, (b) the total delay, (c) the average delay, (d) the maximum queue length (in vehicles), and (e) the longest vehicle delay under FIFO.
