Question

A calibrated utility function for travel in a medium sized city by automobile, bus, and light rail is:

Ua = a - 0.002 X1 – 0.05 X

Where X1 is cost of travel (cents) and X2 is the travel time (min). Calculate the modal split for the given values:

Mode	a	X1	X2
Automobile	-0.30	125	27
Bus	-0.35	71	31
Light rail	-0.40	85	38

If a parking fee of $1.50 per trip is imposed, what would be the split to the other two modes?
