Fundamentals of Transportation/Mode Choice/Problem

TProblem
Problem:

You are given the following mode choice model.

U_{ijm} = -1 C_{ijm} + 5 D_T\,\!

Where:

  • C_{ijm} = travel cost between i and j by mode m
  • D_T = dummy variable (alternative specific constant) for transit

and Travel Times

Auto Travel Times
Origin\Destination Dakotopolis New Fargo
Dakotopolis 5 7
New Fargo 7 5
Transit Travel Times
Origin\Destination Dakotopolis New Fargo
Dakotopolis 10 15
New Fargo 15 8

A. Using a logit model, determine the probability of a traveler driving.

B. Using the results from the previous problem (#2), how many car trips will there be?
