Modal Choice

Question 1

is the process where the means of traveling is determined. The means of travel automobiles, include private public transportation, walking, bicycling, etc.

Answer 1

• Mode choice

Question 2

In most travel models, it is applied to travel that has already been estimated, where the origin and destination are already known (e.g. tours, group of tours).

Answer 2

mode choice

Question 3

plays a crucial role in various transportation analysis models, (i.e., for evaluating the impact of major transportation investments).

Answer 3

mode choice

Question 4

vital in pricing policy analyses, where fare adjustments may deter the use of certain modes.

Answer 4

mode choice

Question 5

Types of mode choice models

Answer 5

• direct generation models
• trip end models
• trip interchange models

Question 6

• transit trips can be estimated directly by calculating either the total number of person trips or the number of trips made by car drivers

Answer 6

Direct Generation Model

Question 7

• This approach assumes that system attributes, like travel time, cost, and convenience, are not relevant factors.

Answer 7

Direct Generation Model

Question 8

• These “pretrip” distribution models is when transit service is either the clear “choice” or very poor that riders have no other choice.
• When various modes compete for drivers, system factors are then taken into account.

Answer 8

Direct Generation Model

Question 9

• to estimate the percentage of total person or auto trips that will use transit, calculations are made before the trip distribution phase, relying on the land-use or socioeconomic characteristics of the area.

Answer 9

Trip End Model

Question 10

• Takes into account system level-of-service variables like relative travel time, travel cost, the economic status, and the quality of travel service.

Answer 10

Trip Interchange Model

Question 11

An example of Trip Interchange Model is the ___

Answer 11

(QUICK RESPONSE SYSTEM) QRS method

Question 12

• The data required for estimating mode choice include:

Answer 12

o Distance between zones by auto and transit
o Transit fare
o Out-of-pocket auto cost
o Parking cost
o Highway and transit speed
o Exponent values, b
o Median income
o Excess time

Question 13

represents the logarithmic ratio of the probability of selecting a particular mode to the probability of not selecting it.

Answer 13

Logit Model

Question 14

This choice model is used to explain the proportion of travelers using a specific mode, or the probability that an individual traveler chooses that mode, multiplied by the total number of travelers.

Answer 14

Logit Model

Question 15

a method that incorporates service factors to estimate mode choice

Answer 15
