Fundamentals of Transportation/Mode Choice/Homework

Homework 1. Identify five independent variables that you believe affect mode choice. Pose hypotheses about how each variable affects share of travel by each mode. 2. Explain Independence from Irrelevant Alternatives 3. You are given the following mode choice model. Where: travel time between i and j by mode m dummy variable (alternative specific constant) for transit dummy variable (alternative specific constant) for walking Here auto is assumed the baseline mode. The auto travel time between zones (in minutes) is given by the following matrix: Origin \ Destination To Dakotopolis To New Fargo From Dakotopolis 5 9 From New Fargo 9 4 The transit travel time between zones (in minutes) is given by the following matrix: Origin \ Destination To Dakotopolis To New Fargo From Dakotopolis 10 15 From New Fargo 15 8 The walk travel time between zones (in minutes) is given by the following matrix: Origin \ Destination To Dakotopolis To New Fargo From Dakotopolis 10 30 From New Fargo 30 10 Using a logit model, what is the probability of a traveler taking transit? /Homework
