Weather conditions may affect the demand for transportation in certain situations, but they are not a primary factor that influences demand.

Modal demand refers to the demand for a specific mode of transportation, such as cars, buses, or trains.

Travel surveys, economic models, and historical data analysis are all methods used to estimate the demand for transportation.

In general, the demand for transportation is negatively related to the price of transportation, meaning that as the price increases, demand decreases.

Induced demand refers to the increase in demand for transportation that results from the expansion of transportation infrastructure.

Elasticity of demand measures the responsiveness of demand to changes in price.

Higher parking fees may discourage people from driving, but they are not likely to increase the demand for public transportation.

Peak demand refers to the demand for transportation during periods of high traffic volume, typically during rush hour.

Pricing strategies, land use planning, and transportation infrastructure investment are all strategies used to manage demand for transportation.

In general, the demand for transportation is positively related to economic growth, meaning that as the economy grows, demand for transportation increases.

Neural network models are not typically used as transportation demand models.

Long-term demand refers to the demand for transportation over a period of several years or decades.

Consumer preferences are not a primary factor that influences the demand for freight transportation.

Off-peak demand refers to the demand for transportation during periods of low traffic volume, typically during non-rush hour periods.

Building more roads is not a strategy for reducing the demand for transportation, as it can lead to induced demand.
