Which of the following is NOT a component of traditional travel demand modeling?

Traditional travel demand modeling is a structured approach used to forecast future travel patterns and is generally composed of several distinct components. These components typically include trip generation, mode split, and trip assignment.

Trip generation estimates the number of trips originating from different locations based on land use characteristics. Mode split refers to the distribution of travel among different modes of transportation, such as driving, public transit, or walking. Trip assignment allocates the expected trips onto the transportation network, illustrating how many trips will use particular routes.

Route optimization, while crucial in transportation planning, is not a component of traditional travel demand modeling. Instead, it focuses on finding the most efficient routes for vehicles based on various criteria, such as travel time or distance, rather than on predicting travel patterns. Therefore, it does not fit within the conventional framework of travel demand forecasting methods.
