The following 3 Travel Demand Forecasting models were created to estimate the number of peak-hour trips in the suburb of Croydon:
T1 = 1.0 + 0.3(household size) + 0.01(household income in thousands of $)
T2 = 1.5 + 0.2(household size) + 0.01(household income in thousands of $)
T3 = 0.5 + 0.5(household size) + 0.01(household income in thousands of $)
The suburb has a total of 3500 households with an average of 4 people per household, an average household income of $90,000 and survey data shows that it generates a total of 11,550 trips in the peak-hour. Which of the above models is the most accurate?
A. T1
B. T2
C. T3
D. Can't say as 2 or more models are equally accurate.
hree routes connect an origin and a destination with performance functions: ?1=8+0.5?1; ?2=1+2?2; and ?3=3+0.75?3; with the x’s being the traffic volume expressed in thousands of vehicles per hour and t’s being the travel time expressed in minutes. If the peak hour traffic demand is 3400 vehicles, determine user equilibrium traffic flows. [Hint: Note that one of the paths will not be used under the equilibrium condition
