1. Consider a Poisson regression model for the number of social/recreational trips generated during a peak-hour period that is estimated by BZi = −0.75 + 0.025(household size) + 0.008(annual household income, in thousands of dollars) + 0.10(number of nonworking household members). Suppose a household has five members (three of whom work) and an annual income of $100,000. What is the expected number of peak-hour social/recreational trips, and what is the probability that the household will not make a peak-hour social/recreational trip?
2. If small express buses leave the origin described above and all are filled to their capacity of 20 travelers, how many work-trip vehicles leave from origin to destination above during the peak hour?
