The following table shows the the data collected from a household survey for 3 zones A, B and C. Income Zone No. of Households No of Workers No of Residents 2.0 Low A 3.0 Low B C 2.5 High 10,000 20,000 40,000 Assume that household trip generation model was estimated using a linear regression model as follows Where Trip rate no. of trips per household for a given zone NWORK = no. of workers per household Number of workers 1 or less 2 or more 1.0 2.0 2.0 Trip rate = 0.2 + 0.5 xNWORK + 1.1× INC INC = a dummy variable for income level (1 = high, 0 = low) Assume also that a crossing classification model was developed, which classified households based on household income (low and high) and number of workers in household (1 or less and 2 or more workers per household). The trip rates are shown as follows Low 0.8 1.2 Income High 1.0 2.3 (a) Calculate number of trips for Zone B using the linear regression model (b) Calculate number of trips for Zone B using cross-classification model (c) Calculate number of trips for Zone A using the linear regression model (d) Calculate number of trips for Zone A using cross-classification model (e) Calculate number of trips for Zone C using cross-classification model
