During morning peak hour, the passenger demand is 600. Assume that passenger demand is evenly distributed within that period and the average load/occupancy is 50 passengers per bus. Calculate the average headway of a city buses? If the passenger demand increases to be 750, calculate the number of bus units need to be added and the headway shorten?
[T] The following table provides hypothetical data regarding the level of service for a certain highway.
Plot vehicles per hour per lane on the x-axis and highway speed on the y-axis.
Compute the average decrease in speed (in miles per hour) per unit increase in congestion (vehicles per hour per lane) as the latter increases from 600 to 1000, from 1000 to 1500, and from 1500 to 2100. Does the decrease in miles per hour depend linearly on the increase in vehicles per hour per lane?
Plot minutes per mile (60 times the reciprocal of miles per hour) as a function of vehicles per hour per lane. Is this function linear?

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.
