1. A city has a utility function for use in a logit model of the form U = -0.075A-0.05W-0.04R -0.02C where A is the access time in minutes, W is the waiting time in minutes, R is the riding time in minutes, and C is the out-of-pocket cost in cents. (a) What modal distribution would you expect, using the following values for A, W, R, and C, for the four modes used in the city.

1. A city has a utility function for use in a logit model of the form
U = -0.075A -0.05W-0.04R -0.02C
where A is the access time in minutes, W is the waiting time in minutes, R is the riding
time in minutes, and C is the out-of-pocket cost in cents.
(a) What modal distribution would you expect, using the following values for A, W, R, and
C, for the four modes used in the city.

(b) The city is seriously thinking of subsidizing rail and bus by 50%, encouraged biking
by constructing bike paths and thus reducing biking time by 20%, and increasing auto
costs (through higher parking charges) by 10%. What is likely to be the new modal
distribution with these charges?
