8 Mode Choice Flashcards
Is that aspect of the demand analysis process that determines the number (or percentage) of trips between zones that are made by automobile and by transit.
mode choice
_____ attempt to replicate the relevant characteristics of the traveler, the transportation system, and the trip itself, such that a realistic estimate of the number of trips by each mode for each zonal pair is obtained.
mode choice models
The reason for the trip (e.g., commuting, leisure, shopping) can significantly affect the chosen mode.
trip purpose
The perceived time required to use a specific mode plays a vital role in decision-making.
travel time
Financial considerations, including fuel, fares, and parking fees, heavily influence mode choice
cost
The ease of accessing a mode, including its factors like proximity to stops or availability of services, impacts the selection process.
convenience
Attributes such as income, age, car ownership, and personal preferences shape how individuals choose their travel modes.
travel characteristics
4 types of mode choice models
- direct general models
- trip end models
- trip interchange models
- logit models
This method assumes that the attributes of the system are not relevant. Factors such as time, cost, and convenience are not considered.
direct generation models
They do not rely on trip generation or distribution steps
direct generation models
Mode shares are determined from these variables without detailed interaction between zones or trips.
direct generation models
They are simpler and often used for quick analysis in small-scale projects.
direct generation models
These models consider the characteristics of the trip’s origin or destination.
trip end models
They evaluate factors like land use, population density, or employment at the ends of a trip.
trip end models
Mode choice is determined based on the trip purpose and characteristics of the zones but does not directly consider the interaction between the origin and destination.
trip end models
System level-of-service variables are considered, including relative travel time, relative travel cost, economic status of the trip maker, and relative travel service.
trip interchange models
An example of this procedure is illustrated using the QRS method which takes account of service parameters in estimating mode choice.
trip interchange models
This form considers the relative utility of each mode as a summation of each modal attribute. Then the choice of a mode is expressed as a probability distribution.
logit models
